The Jamf Enrollment process is having issues on macOS Big Sur Beta 1
Time to Start Testing Big Sur Beta Against Your MDM Workflows!
By now, you have already heard the news, the annual macOS release is here! The new OS is called Big Sur and is now macOS 11! That’s neat and all, but it’s time to start testing workflows. Time is of the essence, we only have about 10 or so beta releases before Big Sur is production ready.
Every year I put together a “Need to Know” article on all the latest macOS Beta changes. You can check out the post below, I will keep it updated new information comes out.
Big Sur enrollment using Jamf Pro is currently Broken. If you attempt to take Big Sur Beta 1 through DEP/Automated Enrollment it will fail. Behind the scenes, the jamf binary is not installing properly. A quick workaround is to build out a 10.15.5 Mac, then enroll it in to Jamf Pro. Run the Big Sur Upgrade and your Mac will be fully working with Jamf Pro.
As far as I can tell, the enrollment process is InstallApplication a zero payload pkg which then curls down the jamf binary. The binary is then trying to install the JSS communication certificate via the profiles command and this doesn’t work with Big Sur. The end result is I have a mac with the binary but no way for it to “phone home”.

Fresh Big Sur Install Workaround
You just finished installing Big Sur, and don’t want to waste time erasing the drive + reinstalling the OS two times! There has to be a better way.
The workaround is pretty simple if your Mac serial number is in DEP.
1. Build out fresh Big Sur Beta 1 Mac
2. You are now at the Setup Assistant
2. Do not connect the Mac to WiFi or Ethernet
4. Create Local Account
5. Connect to network
6. Run sudo profiles renew -type enrollment
7. You will see an enrollment notification in the upper right corner.
10. Copy QuickAdd.pkg to Target Mac & Install Or run QuickAdd.pkg from downloads.
That’s it! You are now enrolled into Jamf Pro. Tomorrow I will try with the https://casperserverhere.domain.com:8443/enroll method to see if can figure out . This would be for any mac that is not enrolled into DEP.
Hat Tip goes out to MacAdmin @kennyb for testing this method. I was able to verify the method this afternoon.
Jamf fix Coming in the Next Beta Release
Jamf said just today, that they found the enrollment issue last week and a fix is coming in the next beta release!
Non DEP Mac Enrollment
MacAdmin @aaronpolley put together instructions for enrolling a device that is not in DEP. In his example, he is pulling directly from his Jamf Cloud instance and manually creating a Jamf configuration file.
Aaron’s instructions start below.
If anyone is testing macOS 11 Beta and using Jamf Pro as your MDM, the jamf binary fails to install and complete the enrolment (as some mentioned here already)I am putting together some notes to submit in the correct places….. however for the short term here are the steps to get the Binary installed and complete the enrolment (for either DEP or UIE)
sudo -i
mkdir -p /usr/local/bin/ mkdir -p /usr/local/jamf/bin/ cd /usr/local/jamf/bin/
You will need to trust the CA cert using your admin password via UI password prompt rather than it passing through via CLI when rootas in the pastAlso as shared previously this gives some greate debugging feedback WHILE the initial MDM enrolment is occuring, so best run whilst doing a DEP Nag enrolment (profiles renew -type enrollment) or via UIE:
Install macOS Big Sur 11 on VMware Fusion & Parallels Desktop
How To Install macOS Big Sur on VMware Fusion and Parallels Desktop.
Like clockwork, Apple delivers a new macOS every year. MacAdmins need to start testing the new OS right way. Running the new os in a virtualized environment is the way to go. The only problem is, sometimes the new OS will not install on the current version of VMware Fusion or Parallels Desktop.
Many MacAdmins have already jumped in to find out if macOS Big Sur will install on Fusion or Parallels. The initial report is that a straight install will NOT work. The macOS Big Sur installer presents this error to you.
The operation couldn't be completed. (BIErrorDomain error 3.)

Updates – 7/08/20
VMware Fusion Tech Preview 20H2 is now available!!
VM Tools – Even though Big Sur to works on Parallels and Fusion, do not install VM tools yet. Some reports say that after installing VM tools the system boots fine YMMV.
Parallels Tools – VM can get stuck on a black screen after the reboot. Would recommend not installing the tools.
Parallels – VRAM seems suck at 3mb, causing slow response.
Keyboard & Login Issues – Getting reports that VM’s are not accepting certain keys. 1, 2, t and y keys. You need to hold FN key to make them work.
3. Creating a bootable Big Sur ISO
The instructions below will create a bootable Big Sur ISO.
hdiutil create -size 12G -fs hfs+ -volname macOSInstaller -type SPARSEBUNDLE /Users/Shared/macOSInstaller
hdiutil attach /Users/Shared/macOSInstaller.sparsebundle
"[path to]/createinstallmedia" --volume /Volumes/macOSInstaller --nointeraction
hdiutil detach /Volumes/Install\ macOS\ Beta
hdiutil makehybrid -o /Users/Shared/macOSInstaller /Users/Shared/macOSInstaller.sparsebundle
# Now create a macOS 10.15 VM with a 50 GB disk i Fusion
# Connect the virtual optical drive to /Users/Shared/macOSInstaller.iso
# Boot and install (you may need to "adjust" the disk Disk Utility to recognize the full capacity)

5. How To Install Big Sur 11 on VMware Fusion
Requirements
Disk Size – 50-60GB+ Virtual disk size required (40GB Standard size does not seem to work)
Clean install vs Upgrade – A Big Sur Upgrade from Mojave or Catalina is the easiest path. Usually all the values that I mention below are already set, so you have a clear path.
Mac Compatibility – Note if the hw.model is not supported for Big Sur the install will fail. You can fake it by setting a different hw.model and board-id. Be sure to check the compatibility list here.
Install Instructions
If you would like to use the same values from your Mac you can set this attribute. HT @lamw for the simplification!
smbios.reflectHost = "TRUE"
You can also manually set the the required values. The example below = 16-inch MacBook Pro.
hw.model = "MacBookPro16,1"
board-id = "Mac-E1008331FDC96864"
serialNumber = "serialnumberhere" (For DEP Enrollment testing)
To get the values you can run the following commands
Error message – “Not enough physical memory is available to power on this virtual machine with its configured settings.” – communities.vmware.com/thread/638385
Using Fusion 11.5.5 on Mojave 10.14.6, modifying the vmx file was unnecessary. I did a fresh install of Catalina 10.15.4 in a new VM, copied the macOS Beta installer to the VM, and ran the installer. It installed and booted fine. Note that I did not install the VMware Tools to the VM prior to installing macOS Beta. I had a prior Catalina VM with the Tools installed, and upgrading to the macOS Beta resulted in failures at the login screen after the Beta upgrade. So do the Beta upgrade on a fresh Catalina install and it should work fine (at least from 10.15.4).
Please note, if I added ‘board-id.reflectHost = “TRUE”‘ to the .vmx, the Fusion refused to boot the VM with an error that the vmx file is corrupted.

6. How To Install Big Sur 11 on Parallels Desktop
1. Create a new VM by installing a fresh copy of 10.15 Catalina
2. Do not install Parallels Tools
3. The install requires at least 80gb or more
4. Install beta profile
5. Download Beta
6. Set the following values set under Hardware > Boot Order > Advanced Settings > Boot Flags.
7. Create a 2nd admin account. (this can help with login problems after the Big Sur install. Some users are saying that they can’t login with the original account. If that happens, login with the 2nd account.)
devices.mac_hw_model="MacBookPro16,1"
devices.smbios.board_id="Mac-E1008331FDC96864"
Keep in mind, both examples above are from a 2019 16-inch MacBook Pro. You can get the correct hardware values by running the following commands.
sysctl hw.model = Model
ioreg -l | grep board-id = BoardID
Try to install Big Sur. If that doesn’t work, try the instructions below.
MacOS Big Sur 11.0 -10.16 (20A4299v) Beta 1 was released today on June 22nd, 2020 at 2:00 CST right after the keynote.
macOS Big Sur 11.0 Patch Notes
Just like last year, the 11.0 beta 1 patch notes list is huge! The amount of detail is just what MacAdmins are looking for! Let me give you some stats from the 11.0 Beta 1 Patch notes document.
Updating to macOS Big Sur 11 beta from previous versions of macOS might take significantly longer than expected. Data loss could occur if the update is interrupted. (59101197)
If macOS Big Sur 11 beta is installed into the same APFS container as previous versions of macOS, system software updates can no longer be installed on the previous versions of macOS. (64411484)
Installing a new kernel extension requires signing in as an Admin user. During kernel extension development, every time a kernel extension is changed, it must be signed and notarized. In both cases, your Mac must be restarted to load the extension. (55068348)
If you updated to macOS Big Sur 11 beta from a previous version of macOS, Software Update might show “Unable to check for updates – Failed to download the documentation for the minor update. Please try again later”. (63158434)Workaround Below
Kernel extensions using certain deprecated KPIs no longer load. Refer to the support page. While macOS Big Sur remains in development, you can temporarily disable System Integrity Protection to allow these deprecated extensions to load. (55068348)
macOS Big Sur 11 beta improves system security by requiring an administrator password when a certificate trust settings change is made in the admin trust domain. Running as the root user alone is no longer sufficient to modify certificate trust. User trust domain settings continue to require confirmation by entering the password for the user’s account.
Now that macOS Big Sur 11.0 Beta is live, start testing as soon as you can! You will want to submit any bugs that you find into Apple ASAP. If you get bugs in quickly, they could be fixed in the current beta cycle instead of waiting until after the public release. If not, you could be waiting months before the fix is put into a dot release combo update.
macOS Big Sur 11.0 (20A4299v) Beta 1 Release Notes
I always post the full patch notes to this page to document them for you. The reason behind that is that Apple will usually just replace over the old patch notes so you are then unable to see what was fixed in the previous release.
Overview
The macOS 11 SDK provides support to develop apps for Macs running macOS Big Sur 11. The SDK comes bundled with Xcode 12 beta. For information on the compatibility requirements for Xcode 12 beta, see Xcode 12 Beta Release Notes.

Known Issues
If the desktop picture was never changed from the default macOS Catalina 10.15 image, it will persist after updating to macOS Big Sur 11 beta, even though the new default desktop picture is displayed in Desktop and Screen Saver preferences. (64390185)
Installer and Software Update
Known Issues
If you updated to macOS Big Sur 11 beta from a previous version of macOS, Software Update might show “Unable to check for updates – Failed to download the documentation for the minor update. Please try again later”. (63158434)Workaround:
Start up from macOS Recovery.
If your data volume is encrypted, use Disk Utility to mount it.
In Terminal type rm -rf "/Volumes/Macintosh HD - Data/private/var/folders/zz/zyxvpxvq6csfxvn_n00000y800007k".
Restart your Mac.
You might need to adjust Energy Saver settings so your Mac doesn’t go to sleep while preparing to install macOS Big Sur 11 beta. (63166401)
APFS containers with non-default allocation block sizes aren’t currently supported for installation. (64312561)
Update iMac Pro to macOS High Sierra 10.13.6 or later before installing macOS Big Sur 11 beta. (64314272)
Installation might pause on Macs that don’t have input devices connected. (64348347)Workaround: Connect an input device and dismiss the alerts to continue installation.
You might be unable to install macOS Big Sur 11 beta onto additional volumes. (63677460, 64445236)Workaround: Create a bootable installer using the createinstallmedia command.
Software Update might unexpectedly indicate updates for your Mac are being managed by swscan.apple.com, instead of indicating your Mac is enrolled in the Apple Beta Software Program. This doesn’t impact your ability to update macOS Big Sur 11 beta. (64407436)
If macOS Big Sur 11 beta is installed into the same APFS container as previous versions of macOS, system software updates can no longer be installed on the previous versions of macOS. (64411484)
Installation on Core Storage Fusion volumes with FileVault encryption enabled isn’t currently supported. (64472080)
Kernel
New Features
The kern.argmax limit has been increased, allowing programs to receive longer argument lists. (48661669)
Darwin kevent now allows non-parent processes to register for NOTE_EXITSTATUS, which delivers the same values as the wait() family of functions in the event data. Refer to the wait4() man page for more information. This event is subject to the following security checks:
The requesting process is allowed to send signals by sandbox restrictions.
The requesting process and the target process are running as the same user or the requesting process has root privileges. (58134463)
Known Issues
Installing a new kernel extension requires signing in as an Admin user. During kernel extension development, every time a kernel extension is changed, it must be signed and notarized. In both cases, your Mac must be restarted to load the extension. (55068348)
Remote panic dumps aren’t currently available. (57915324)
New in macOS Big Sur 11 beta, the system ships with a built-in dynamic linker cache of all system-provided libraries. As part of this change, copies of dynamic libraries are no longer present on the filesystem. Code that attempts to check for dynamic library presence by looking for a file at a path or enumerating a directory will fail. Instead, check for library presence by attempting to dlopen() the path, which will correctly check for the library in the cache. (62986286)
kmutil install might fail to build a development kextcache. (63772702)Workaround: Copy the release .elides to the locations of the development .elides:sudo cp /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.development.elidessudo cp /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.kasan.elides sudo cp /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.debug.elidessudo cp /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.development.elidessudo cp /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.kasan.elidessudo cp /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.debug.elides
Use only absolute paths with the --volume-root option of kmutil, and don’t use a trailing /. (63773848)
After removing a DriverKit extension, restart your Mac to complete uninstallation. (63995046)
Adhoc signed kernel extensions are displayed with a developer name of unknown in update dialogs and in Security preferences. (64215260)
Symbols exported by both xnu and Apple kernel extensions will change. Recompile your kernel extension with each update to macOS Big Sur 11 beta to ensure compatibility. (64262563)
Moving a kernel extension bundle out of /Library/Extensions might not completely uninstall it. (64331929)Workaround:
Remove the extension from /Library/Extensions.
Boot to macOS Recovery.
Run Terminal.
Enter the command kmutil invoke-panic-medic.
Restart your Mac.
Follow the prompt to open System Preferences and navigate to Security & Privacy.
Follow the prompt to restart.
An unexpected System Extension Updated alert for third-party kernel extensions which are included in macOS might appear. These include: Accusys, Inc., ATTO Technology, Inc., Areca Technology Corporation, CalDigit, Inc., HighPoint Technologies, Inc., Promise Technology Mobile Apps, and Other World Computing. (64337113)
Deprecations
Kernel extensions using certain deprecated KPIs no longer load. Refer to the support page. While macOS Big Sur remains in development, you can temporarily disable System Integrity Protection to allow these deprecated extensions to load. (55068348)
Localization
Known Issues
Certain languages might exhibit clipped or misaligned layout. (63105445)
Certain languages might display unlocalized text. (63105674, 64040564, 64045718)
Some keyboard shortcuts might not work when running macOS Big Sur 11 beta in a language other than English. (63834383)
Location
Known Issues
Widgets have access to location information even if the NSWidgetWantsLocation key isn’t in their Info.plist. (61953645)
New APIs are available for using os_log from Swift as part of the os framework:
A new type Logger can be instantiated using a subsystem and category and provides methods for logging at different levels (debug(_:), error(_:), fault(_:)).
The Logger APIs support specifying most formatting and privacy options supported by legacy os_log APIs.
The new APIs provide significant performance improvements over the legacy APIs.
You can now pass Swift string interpolation to the os_log function.
Note: The new APIs can’t be back deployed; however, the existing os_log API remains available for back deployment. (22539144)
Mac Catalyst
Known Issues
Content Extensions require a temporary workaround. (57442394)Workaround: Add the following key/value pair to the NSExtension dictionary in the Info.plist: "NSExtensionContainingViewControllerClass" = "_UNNotificationContentExtensionViewController".
If Messages is launched immediately after logging into iCloud, a login window might be displayed unexpectedly. (56309057)Workaround: Relaunch Messages after a few minutes or try restarting your Mac.
You might be unable to type in the photo picker search field when attaching a photo. (60011306)Workaround: Click the search field, press the tab key, then click the search field again.
You might receive an alert that indicates the maximum number of pinned conversations has been reached. (62919406)Workaround: Pin the conversation using drag and drop instead of using a swipe action or quick action with Haptic Touch.
Keyboard navigation to move focus between controls isn’t currently available. (63987810)
Messages Preferences are inaccessible until at least one message has been sent or received. (64122975)

Message outlines might be missing when printing or exporting a conversation as a PDF. (64181169)
The first and last name fields in Messages Preferences might be misaligned. (64346872)Workaround: Set up your name in Messages Preferences by following the placeholder text then close and reopen Messages Preferences.
Metal
Known Issues
The logs property isn’t currently available from Swift while using Shader Validation. (64055248)
Migration Assistant
Known Issues
You might need to reset the password for a Standard account after migration, if the previous password doesn’t work. (63878129)Workaround: Log into an Admin account and change the Standard account’s password in the Users & Groups system preference.
Motion
Known Issues
Many elements of the user interface are currently missing when running Motion on macOS Big Sur 11 beta. (62531765)
Music
Known Issues
Music might quit unexpectedly while using the search field. (64183834)
Networking
New Features
Experimental HTTP/3 support can be enabled in Safari via Experimental Features in the Developer menu, and enabled system-wide using the Terminal command defaults write -g CFNetworkHTTP3Override -int 3. (62969220)
Known Issues

Known Issues
Safari might quit unexpectedly when opening the Start Page if Frequently Visited Sites are visible as thumbnails. (63945984)Workaround: Make the window wider, hide the sidebar, or Control-click on Frequently Visited Sites and choose View as Icons.
Security
New Features
macOS Big Sur 11 beta improves system security by requiring an administrator password when a certificate trust settings change is made in the admin trust domain. Running as the root user alone is no longer sufficient to modify certificate trust. User trust domain settings continue to require confirmation by entering the password for the user’s account. This change may affect you if one of the following is true:
You have written scripts which call /usr/bin/security add-trusted-cert -d ... as root.
Your process runs as root and calls the SecTrustSettingsSetTrustSettings function to trust a certificate.
Workflows that add trust settings in the admin trust domain, such as for an enterprise root certificate, may require modification if the user can’t authenticate as an administrator at the time settings are changed. (21855995)Workaround: Use Apple Configurator 2 to create and install a configuration profile containing your root certificate.
Spotlight
Known Issues
When quickly typing a search query in Spotlight, the result from a previous search might appear, then pressing return may create a wrong launch shortcut for subsequent queries. (64428836)Workaround: Type your query and click the desired result from the list that appears.
If you can’t find an application using Spotlight, launch the application at least once using Finder. (64463806)
SwiftUI
Known Issues
Disclosure groups in Forms might produce unexpected results. (64079102)
Nested disclosure groups generated by OutlineGroup might produce unexpected results. (64097731)
The SceneStorage property wrapper isn’t yet supported. (64414712)
A label used with a symbol image might appear misaligned. (60193698)
SystemExtensions
Known Issues
Driver extensions might not launch on-demand after installation. (51229724)Workaround: Disable System Integrity Protection, then launch Terminal and execute the following command before approving the newly installed driver: sudo touch /Library/DriverExtensions.
Touch ID
Known Issues
Touch ID might become unexpectedly disabled on Macs with a T2 Security Chip after installing multiple operating systems. (62608379)Workaround: Reset the SMC of your Mac.
Rebuilding against the iOS 14, macOS 11, watchOS 7, and tvOS 14 SDKs changes uses of GeometryReader to reliably top-leading align the views inside the GeometryReader. This was the previous behavior, except when it wasn’t possible to detect a single static view inside the GeometryReader. (59722992) (FB7597816)
MacOS Big Sur 11.0 – Updated Index of Need to Know Changes & Links
WWDC 2020 – macOS Big Sur 11.0
WWDC is here again! For the first time ever, Apple’s Worldwide Developers Conference will be 100% Virtual. MacAdmins everywhere are wondering what changes macOS Big Sur will bring and how deployment workflows will be affected. I hope to help you answer multiple question with this article. This year I will follow the same format as my previous MacOS 10.15 Catalina – Updated Index of Need to Know Changes & Links post. Be sure to check back frequently, I will keep you up to date with the latest macOS Big Sur 11.0 changes!
macOS Big Sur brings a refined new design, powerful controls, and intuitive customization options to the most advanced desktop operating system in the world.
Faster updates – Once macOS Big Sur is installed, software updates begin in the background and complete faster than before — so it’s easier than ever to keep your Mac up to date and secure.
Updated menu bar – The menu bar is now taller and more translucent, allowing your desktop picture to extend from edge to edge. Words lighten or darken based on the color of your desktop picture. And pull-down menus are larger, with more space between the lines to make everything easier to read.
Floating Dock – The redesigned Dock is lifted from the bottom of your display and is more translucent, allowing your desktop wallpaper to shine through. And app icons are all-new and even easier to recognize.
Updated Notification Center – A redesigned Notification Center puts all your notifications and widgets into a single, dedicated column. Notifications are automatically sorted by most recent, and redesigned Today widgets deliver information at a glance.
New icons for apps – App icons have been redesigned to feel both familiar and fresh. Icons have a uniform shape but retain the stylistic touches and details that give Mac its character.
New and updated sounds – System sounds are all-new and even more pleasing to the ear. The new system alerts were created using snippets of the originals, so they sound familiar.
New Control Center – Designed just for Mac, the new Control Center consolidates your favorite menu bar items into a single place to give you instant access to the controls you use most. Just click the Control Center icon in the menu bar and adjust Wi-Fi, Bluetooth, AirDrop, and other settings — without opening System Preferences.
Signed system volume – macOS Big Sur introduces a cryptographically signed system volume that protects against malicious tampering. It also means that your Mac knows the exact layout of your system volume, allowing it to begin software updates in the background while you work.
Safari extensions on the App Store – An all-new extensions category on the App Store showcases Safari extensions with editorial spotlights and top charts, making it easier to discover great extensions from developers. All extensions are reviewed, signed, and hosted by Apple for your security.
Privacy information on the App Store – A new section on each app’s page on the App Store will help you understand the privacy practices of the app before you download it.9 It’s similar to the way nutrition labels help you understand what’s in food before you buy it.
Self-reported privacy practices – Developers self-report their app privacy practices on the App Store.9 See the types of data their app might collect — like usage data, contact information, or location — and whether that data is shared with third parties.
App Privacy is Displayed in a simple format – Just as nutrition labels are convenient and easy to read, an app’s privacy information on the App Store is displayed in a consistent, simple format.9 This lets you quickly and easily understand the app’s privacy practices.

Software Update For increased security, major releases of macOS are not hidden when using the --ignore flag and the softwareupdate command starting with macOS 10.15.5. A major release is defined as one which receives a name, such as macOS Catalina. Starting with macOS 10.15.4, major releases of macOS can be deferred for up to 90 days using MDM.
networksetup Command Starting with macOS 10.15.5, the networksetup command behaves differently when run as a standard user versus an admin user. Standard users can do the following: • 1. Read various network settings • 2. Turn Wi-Fi power on or off (networksetup -setairportpower en0 on) • 3. Change the Wi-Fi access point (networksetup -setairportnetwork en0 ExampleWiFiAP) Other network settings can no longer be modified by standard users via networksetup. For admin users, networksetup will continue to behave as it has in previous releases of macOS, provided System Preferences > Security & Privacy > Advanced… > “Require an administrator password to access system-wide preferences” is unchecked (which is the default state). If it is checked, admins will be bound by the same constraints as standard users when using networksetup.
How To reissue a FileVault 2 Personal Recovery Key
It’s good practice to have a backup of important things in your life. You wouldn’t only keep one set of keys to your house or car. The same goes for your FV2 Encrypted Mac. The FileVault Personal Recovery Key is your backup key to your Mac. If your account password is not working or if you can’t remember the password, the Recovery Key will be the only way to get to your data.
Two Different Types of FileVault 2 Recovery Keys
When encrypting your Mac, you have two different types recovery key options.
(PRK) Personal Recovery Key – Every Mac has a unique Recovery Key.
(IRK) Institutional Recovery Key – One Recovery Key for every Mac
While it may be convenient to have one key for every Mac, having a Institutional Recovery Key is like having a Master Key to an Apartment Complex. If that key is stolen or lost, the bad guy has a key to every single apartment unit. The same thing goes for the (IRK) if one user has the key, it’s known for every single Mac.
The PRK is the way to go, as each Mac has a unique key.
I previously wrote about how to use the PRK to recover data from a Mac using Target Disk Mode.
Reissue the FileVault 2 Recovery Key with FV2 Enabled Username and Password
To generate a new FileVault 2 Personal Recovery Key we will be using the fdesetup binary.
First you can check to see if your Mac is using a PRK or IRK.
sudo fdesetup haspersonalrecoverykey = true or false
sudo fdesetup hasinstitutionalrecoverykey= true or false
Now we can change the recovery key using username and password.
sudo fdesetup changerecovery -personal
Enter the user name:mrmacintosh
Enter the password for user 'mrmacintosh':
New personal recovery key = 'Z5V7-K464-PEVT-09OX-Q2EW-8FO8'
This works for 10.13 – 10.15
Reissue the FileVault 2 Recovery Key using the Current Personal Recovery Key (PRK)
Staring in 10.14, you can now use the current Personal Recovery Key to generate a new PRK.
You will be using the UUID of the Personal Recovery User and the current PRK as the password.
Find the UUID of the Personal Recovery Key User
sudo fdesetup list -extended
ESCROW UUID TYPE USER
0A1BCDC3-49BD-4E00-B741-813E143AD1E2OS User mrmacintosh
EBC6C064-0000-11AA-AA11-00306543ECAC Personal Recovery Record
Note: The UUID of the Personal Recovery User is the same very every FV2 Encrypted Mac.
Let’s change it.
sudo fdesetup changerecovery -personal
Enter the user name:EBC6C064-0000-11AA-AA11-00306543ECAC
Enter the password for user 'EBC6C064-0000-11AA-AA11-00306543ECAC':
New personal recovery key = 'Z5V7-K464-PEVT-09OX-Q2EW-8FO8'
For the password field, all we need to do is enter in the current FV2 PRK.
NOTE: If you want to send the Recovery Key to Jamf Pro, you need to run Recon twice.
Running commands are great for 1 or 2 Macs, but what if I have to fix more than that?
The guys at HCS Technology Group wrote up an excellent article showing us how to create a policy for this. The policy will search for all Macs that do not have a valid recovery key and will remediate with a script kicked off by a Jamf Policy.
Hat Tip goes out to Johan McGwire aka yohan on #MacAdmins. He brought up the 2nd way to reissue the Personal Recovery Key with the current PRK. Johan the expert behind the following projects. Check them out!
What is the minimum and maximum macOS Version my Mac can run?
Do you need to downgrade or upgrade macOS on your Mac? This page will show you the oldest and newest version of macOS that you can install on your Mac.
Can I upgrade or downgrade macOS? How many times has this question come up over the years? Probably hundreds if not thousands of times. Mac Hardware has a minimum and maximum version of macOS that can be installed. MacOS versions that come before or after the minimum and maximum listed OS do not have the correct drivers required. At a certain point Apple will decide that a Mac is no longer supported and will not include drivers.
Internet Recovery Version
If your Mac supports Internet Recovery, you can use this guide to find out which version of macOS you will get using the following options.
Newest OS – Option-⌘-R
This option will be the newest or latest version of macOS that can be installed on your Mac.
Shipping OS (Oldest OS Available) – Shift-Option-⌘-R
The “Shipping OS Version” is the macOS version that your Mac originally shipped with from the factory. This is the IR Version that you will see if you use Shift-Option-⌘-R.
NOTE! The “Shipping OS can change to a newer OS release as the hardware gets older. An example of this is a MacBook Pro released with 10.13 but later is shipped with 10.14.
