Internet Recovery, Recovery Partition or HW Diag from macOS

MrMacintosh.com - Boot to Internet Recovery, Recovery Partition or Diagnostics from macOS using nvram or Recovery Selector.app — Boot to Internet Recovery, Recovery Partition or Diagnostics from macOS using nvram or Recovery Selector.app

How to Boot to Internet Recovery, Recovery Partition or Diagnostics from inside macOS.

UPDATE 01/25/21 – Martin Nobel @martinnobel_ – If you want to make an Intel Mac boot into the Startup Manager automatically, type into terminal: “Sudo nvram manufacturing-enter-picker=true”

This means that we can boot to almost every single recovery mode EXCEPT for Internet Recovery!

When an undocumented macOS command or option is discovered, the MacAdmin community gets pretty excited. This is one of those times, as a new nvram key and value was uncovered over the weekend.

If you need to boot to Internet Recovery, you first need to remember the Mac Boot Up Keyboard Combination. Can you remember all of them? I can’t and I work on this stuff every day! Below is the complete list Mac Startup Key Combinations. The second article adds two additional keyboard combinations bringing the total to twelve! The first one will “Reinstall the macOS that came with your Mac, or the closest version still available.” The second command will “Upgrade to the latest macOS that is compatible with your Mac.”

Apple Document – Mac startup key combinations https://support.apple.com/en-us/HT201255

Apple Document – macOS Recovery installs different versions of macOS https://support.apple.com/en-us/HT204904

Undocumented command found that allows you to boot almost all available recovery options from macOS.

Over the weekend Tim Perfitt (founder and CEO of Twocanoes Software, Inc) tweeted this out to his followers.

I made a free & open source macOS app to select your recovery partition on next reboot. Download here: https://t.co/GSSkQgl8c7 #macadmins pic.twitter.com/DgHYrzR4ZS
— timo (@tperfitt) January 25, 2020

Tim, announcing the first version of Recovery Selector.app that could boot to the Recovery Partition from macOS.

Tim found an undocumented nvram command that you could use to boot your Mac to the Recovery Partition from macOS! From there, he had an idea to create an open source app that would allow you to boot to the Recovery Partition without knowing the exact command.

Someone found additional nvram keys and values!

I replied to Tim’s tweet letting him know that I put in an Apple Enterprise Support ticket to see if we could uncover if an Internet Recovery key existed. Before I could hear back from support, someone found and sent the new key internet-recovery-mode over to Tim. He then improved the app allowing you to boot into four different modes!

Nvram Keys and Values

The commands that we needed are set with two different keys and four different values.

The new values and keys are

recovery-boot-mode = Local Recovery Partition Value
unused Boot to Recovery Partition

internet-recovery-mode = Internet Recovery Value
RecoveryModeNetwork Internet Recovery (Shift-Option-⌘-R)
RecoveryModeDisk Recovery Partition (⌘- R)
DiagsModeDisk Boot to Local Apple Hardware Diagnostic (D)
DiagsModeNetwork Boot to Internet/AST Diagnostic (Option-D)

Let’s put it all together, keep in mind you must run the nvram as an administrator.

sudo nvram internet-recovery-mode=RecoveryModeNetwork

sudo reboot

MrMacintosh.com - All four different nvram internet-recovery-mode values and keys — All four different nvram internet-recovery-mode values and keys

Your Mac will immediately reboot and start up in Internet Recovery Mode.

Compatibility, Caveats and Requirements

UPDATE 01/27/20

I tested the above commands with the following hardware and OS versions.

2018 T2 15″ MacBook Pro = 10.15.3 Beta 2
2016 13″ MacBook Pro = 10.14.6
2010 13″ MacBook Air = 10.13.6

This should confirm that the command works from 10.13.6-10.15.3 and on Mac Hardware from 2010-2019.

Network Requirements (For Internet Boot Options)

Wired Ethernet Connection
Wifi = Any WPA2 saved connection.
WPA2 Enterprise WIFI is NOT Supported

The WiFi network Internet Recovery will the Top “Preferred Network” listed to boot to Internet Recovery. If for some reason the Mac can’t connect to that network you will be prompted in firmware to connect to a different WiFi network or ethernet network.

Boot Security Requirements

Firmware Password Protection – can be ON or OFF. If ON then you will be required to enter in the firmware password.
Secure Boot – can enabled , the commands works fine.
FileVault – can be enabled, you do not have to enter in your FV2 password.

Restart Requirements

You do not have to reset the boot disk, clear out nvram commands or reset anything. When you restart the Mac, it will boot right back into macOS.

Twocanoes Recovery Selector.app = Easy Mode!!!

Are you going to remember all of the different nvram keys and values?

Probably not

Why not use one simple open source application to do this for you?

In comes the Recovery Selector.app

MrMacintosh.com - Recovery Selector.app — Recovery Selector.app menu = easy mode for your test Mac or VM!

Tim had the great idea to take all the above command options and put them into one application. Two clicks gets your Mac rebooted to the Recovery Partition, Internet Recovery, Local HW Diagnostics or Internet HW Diagnostics.

Note: Admin access to reboot is not required, the app uses a LaunchDaemon.

You can download and try Recovery Selector.App below.

https://bitbucket.org/twocanoes/recovery-selector/downloads/

UPDATE 01/27/20

Tim put together a nice youtube video showing the process.

https://www.youtube.com/watch?v=fS2s8TY1mrQ

We are only missing one critical nvram Internet Recovery Value.

We are only one nvram value away from perfect.

Option-⌘-R

“Upgrade to the latest macOS that is compatible with your Mac.“

I am going to change my Apple Enterprise Support ticket into an Enhancement Request. If this final value is added we will have all 5 boot modes available in macOS.

List of Mac BoardID, DeviceID, Model Identifiers & Machine Models

MrMacintosh.com - List of Mac BoardIDs, Model Identifiers & Machine Models. Every Mac from 2006-2020 — *List of Mac BoardIDs, Model Identifiers & Machine Models.*

Every Single Mac Board ID from 2006-2021 + M1 Apple Silicon DeviceIDs

This page will be updated with the latest list of Mac BoardIDs, Model IDs and Machine Models. Apple started to document attributes like ModelID on the page below but stopped after 2017.

https://support.apple.com/en-us/HT201608

Most BoardID’s are scattered all over the web but are not all in one updated page. I started with the version Intel based version and will update when new BoardID’s are introduced.

Can I upgrade or downgrade macOS on my Mac?

I wrote an article including every Intel Mac since 2006. The list includes the lowest and highest macOS version that you can install on your Mac.

mrmacintosh.com/can-i-upgrade-or-downgrade-macos-every-mac-from-2006-2020/

What is the BoardID used for?

The macOS installer.app uses the boardID value to figure out if the Mac Model is supported when the user starts the install.

You can find this list inside the macOS installer.app. Look for the InstallESD.dmg After you mount the DMG navigate to /System/Library/CoreServices/PlatformSupport.plist

Inside this plist you will find the list of logic board ID’s that installer supports.

How do I find the Mac BoardID?

To find your BoardID use this command.

ioreg -l | grep -i board-id

The output should read like this

"board-id" = <"Mac-942C5DF58193131B">

How do I find the Mac DeviceID?

To find your T2 DeviceID use this command. HT @eholtam for the command.

/usr/libexec/remotectl get-property localbridge HWModel

10.15.1 Update breaks “Update Keychain Password” Again! + Workaround

MrMacintosh.com - Here we go again, the Update Keychain Password Function is broken again in 10.15.1. 10.15.1 Update Keychain Password — Here we go again, the Update Keychain Password Function is broken again in 10.15.1.

The AD “Update Keychain Bug” was fixed in 10.15.0, only to be Broken again in 10.15.1.

UPDATE: 03/26/20 – The bug is fixed after installing the Catalina 10.15.4 Combo Update!

UPDATE: 02/03/20 – This bug is still not fixed in 10.15.3! Please contact Apple about this if you haven’t already.

When the issue was first reported to me, I really didn’t believe the bug could be back right after it was fixed. You have to understand my frustration here, I first reported this bug back in 10.14.4!!!

mrmacintosh.com/10-14-4-update-breaks-update-keychain-password/

I was disappointed that Apple didn’t fix this bug before the final release of Mojave. Near the end of Mojave, Apple did confirm the issue was fixed in a Beta Build of 10.15.

For Mojave users the fix for the issue would be

Upgrade to macOS Catalina

The bug is back.

During the 10.15 Beta period, I confirmed the bug was fixed in and figured that would be the end of it.

Yesterday, I confirmed the bug is back in 10.15.1.

The Bug is Exactly the same as the 10.14.4 bug.

The 10.15.1 Update Keychain Password bug is the same exact problem as the 10.14.4 issue.

If you change your Active Directory Password off the Mac, you will see the Update Keychain Password Dialog. If you click the 2nd button to UPDATE your login keychain password, the dialog box disappears and a new keychain is created for you. The old Login Keychain is still there but is renamed!

This is what you SHOULD see happen. Once you click the Update Keychain Password button a password box shows up. From here you need to type in your OLD keychain password. Once you do this, your Login Keychain Password is synced up and you are good to go.

Workaround

The good news is, you can remove the “New” keychain and rename your previous login keychain so you can access it again. You can follow the same instructions listed in my 10.14.4 article.

10.15.1 Update Keychain Issue Workaround

Please report this issue to Apple.

I will submit an Enterprise Support ticket tomorrow morning. If you use Mobile Accounts, I would ask that you do the same to build an impact statement. Please reach out to your SE or if you are a regular user support.apple.com/

I’d like to give special thanks to Mr. Macintosh reader Cesar who first reported this issue.

2019 16″ MacBook Pro Catalina 10.15.1 Supplemental Update (19B2106)

UPDATE: 11/14/19

macOS Catalina 10.15.1 Supplemental Update (19B2106) & Forked Full Installer.

The much-awaited MacBook Pro (16-inch, 2019) was just released this morning! You can’t get it just yet, but very soon. (November 15th)

To accompany the new 16″ MacBook Pro, we have a forked Build Version of macOS Catalina 10.15.1 (19B2106) Installer.app. We also have a macOS Catalina 10.15.1 supplemental update.

The macOS Catalina 10.15.1 supplemental update improves the stability and reliability of displays and peripherals with MacBook Pro (16-inch, 2019).
Catalina 10.15.1 supplemental update notes

Supplemental Update ? (UPDATE)

I am not sure what’s going on with this update. You would think that all the new 16″ MacBook Pro’s would just ship with (19B2106). If not then what is the Supplemental update for ?

I am downloading the Supplemental Update now so I can investigate.

UPDATE!

I found the MacBook Pro (16-inch, 2019) shipping 10.15.1 Build Version.

10.15.1 (19B2093)

This means that as soon as you receive the new 16″ MacBook Pro, the 10.15.1 Supplemental Update (19B2106) will show as available.

Model Name

The model name for the new is

MacBookPro16,1

Product ID

macOS Catalina 10.15.1 Supplemental Update = 061-32959

MacOS Catalina 10.15.1 Full Forked Installer.app = 061-45871

BridgeOS Update

This update brings BridgeOS up to 17.16.11600

Update Size

10.15.1 Full Installer.app (19B2106) = 8.65gb

macOS Catalina 10.15.1 Supplemental Update = 8.16gb

This does not really make any sense. Again the Supplemental Update is 8.16gb!!!! only about 500mb smaller than the full install!

UPDATE: 01/22/20 – This problem was reported as FIXED in the latest Mojave 10.14.6 Security Update 2019-002 (18G2022) & Catalina 10.15.2 Update. The fixed T2 BridgeOS version is 17.16.12551. Apple did not list the fix in the 10.15.2 or 2019-002 Security Update notes but DID put them in the AppleSeed 10.15.2 Beta 2 Update Notes. I can’t post them here, but you can check the AppleSeed Patch Notes portal or you can contact Apple Support to confirm if you need further information.

Final Verdict – After further investigation, the problem was NOT the user’s fault. After more users reported what happened during the update I found that the update stalled out during the BridgeOS update phase. The black screen is only supposed to last 2-5 minutes. In reality, the update stopped and the Mac would be on the same black screen for up to 1 hour. The user had NO CHOICE but to shut down the Mac. By that time it was already too late.

Users are Unable to Unlock FileVault 2 if the Mojave 2019-001 Security Update is Interrupted.

This issue was first reported about one month ago on the MacAdmins Slack. It was reported that after some users installed the Mojave 10.14.6 Supplemental Update #3, they were unable unlock their Mac with the FV2 Password or PRK. The issue was not widely reported though so it was thought to be a fluke.

Mojave 2019-001 Security Update

All this changed when the Mojave 2019-001 Security Update was released. MacAdmins started to report the problem again.

I have a Mac that just finished installing the 2019-001 Security Update. I can’t get past the FileVault 2 screen with the password or Personal Recovery Key.

1. Affected Mac Hardware = T2 Machines

I have looked over many reports on the Apple Discussion Forums and MacAdmins Slack Chat and Jamf Nation Posts. It looks like only T2 Equipped Machines.

2019 MacBook Air
2018 MacBook Air
2019 15″& 13″ MacBook Pro
2018 15″ & 13″MacBook Pro
2018 Mac Mini
2017 iMac Pro

2. Affected macOS Build Versions

This issue affects the following macOS Updates.

(18G103) Mojave Supplemental Update #3 – 9/26/19
(18G1012) Mojave Security Update Released on 10/29/19
(17G9016) High Sierra Security Update 2019-006 – 10/29/19
(17G9016) High Sierra Security Update 2019-005 – 9/26/19

3. FileVault 2 Encrypted Machines Only. UPDATE!*

UPDATE! – We now have two separate reports of this happening when the Mac is NOT FV2 Encrypted.

If your Mac is unencrypted you should be fine.

* I have not seen any reports as of 11/09/19, that include a T2 Mac that was not encrypted.

4. Evidence? Reports of a Black Screen Followed by User Power Off

After the reports started to roll in, we started to investigate. One of the common threads is that users reported a problem with the update during the install.

Black Screen – Users reported that the Mac looked like it powered down. They would try to power it back on, interrupting the install process.
Black Screen with Apple Logo & Progress Bar Stuck – While the Update was installing, some users have reported that the update hung or stalled out. This was followed by a power down.

5. Can’t login with FV2 Password or PRK?

After the user powered down the Mac, they reported the following.

Can’t login past FileVault 2 with my Password.
Can’t boot the Mac up with the PRK.

In this situation the Mac is unable to boot up at all. The only thing that the user can do is boot to the Recovery Partition or Internet Recovery.

6. Investigation – Encrypted: ERROR -69808 Confirmation?

After booting to the Recovery Partition we tried to first mount the disk.

This did NOT work!

You can confirm the issue by typing in diskutil ap list

Volume disk4s1
    |   ---------------------------------------------------
    |   APFS Volume Disk (Role):   disk4s1 (No specific role)
    |   Name:                      Macintosh HD (Case-insensitive)
    |   Mount Point:               Not Mounted
    |   Capacity Consumed:         171872342016 B (171.9 GB)
    |   Encrypted:                 ERROR -69808

We would expect that the Encrypted status line should be:

FileVault:                 Yes (Unlocked) 
or
FileVault:                 Yes (locked)

Note the Encrypted line. It should say LOCKED or UNLOCKED. Instead you get ERROR -69808

xartutil CLI Binary

You can also use the xartutil binary to check for the Encryption Keys.

xartutil --list

You should see 2 entries listed = This is a normal output

Total Session Count: 2

If you see

xartutil: ERROR: No supported link to the SEP Present = Not a T2 Mac

If you see

Total session count: 0 = The Encryption Keys are Lost.

7. Workarounds?

Currently no known workaround is available.

We have tried multiple things.

Mounting the disk in the Recovery Terminal
Mounting the disk in Disk utility
Target Disk Mode

8. Should I block this update?

After Reviewing Multiple Reports, the issue only looks to have affected a small number of users. One MacAdmin said out of 150 machines, the issue only affected 2 of them.

I tested this issue out on a 2018 MacBook Pro.

Powered Off during the first Black Screen.
Powered Off during the second Black Screen
Powered Off during the first Security Update Progress Bar
Powered Off during the second Security Update Progress Bar

The BridgeOS Update and the 2019-001 Security Update installed successfully!

If you move forward with the update you can ask users not to interrupt the install process.

9. Will Apple fix this issue?

The black screen BridgeOS update process has been around since 2018. Something must have changed in the 2019-001 Security Update.

If you have this issue please report it to Apple ASAP.
