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)

If I deployed/cached the old 10.15 (19A602) Installer.app for OS Upgrades, do I need to redeploy?
Do I have to replace my deployable 10.15 Installer.app?– Probably Not
If you deployed the old version of the 10.15 (19A602) Installer, you most likely do not need the new (19A603) Version. As noted above, Apple did not change the patch notes and did not mention any changes to this Build Version. The Update most likely has only very minor changes.

Photos is organized by day, month, and year views so it’s easy to find photos or relive your memories. Animations and transitions keep your spot in the timeline so you can switch between views without losing your place.

Developer support
Developers don’t need to do anything for Sidecar support — it just works. Apps with advanced stylus support can use Tablet Events in AppKit to enable pressure and tilt for Apple Pencil. Additionally, developers can specify custom behavior for double-tap on the side of Apple Pencil through a changeMode event.
Continuity Markup and Sketch
Continuity Markup
Write and sketch on PDFs or mark up your documents with Apple Pencil. See the updates live on your Mac as you mark them up on your iPad.
Continuity Sketch
Create a sketch on your iPad using Apple Pencil and easily insert it into any document on your Mac.
Screen Time
Usage reports
Screen Time creates usage reports that show you how much time is being spent on your Mac, which apps are used most, and how many notifications are received. With iCloud, Screen Time combines all your usage information and syncs Downtime settings and App Limits across iPhone, iPad, and Mac.
Downtime
With Screen Time, you can schedule downtime so you (or your child) can only use specific apps you’ve approved.
App Limits
With App Limits, you can set the amount of time you want to use your apps and websites. Set App Limits for total time, categories, or specific apps.
Combined Limits
Create combined limits with a combination of app categories, specific apps, or websites.
One More Minute
When a limit is met, you can tap “One more minute” to give you time to quickly save your work or wrap up a conversation.
Communication Limits let you control who your children can communicate with and who can communicate with them throughout the day and during downtime.
Managed contact list for children
Parents can use Screen Time to manage the contacts that appear on their children’s devices.
Family Sharing
Parents can configure Screen Time from any device — iPhone, iPad, or Mac — and have everything set up for their kids on all their devices.
Security
Enhanced Gatekeeper
Gatekeeper will ensure that all new apps you install — from the App Store or the internet — have been checked for known security issues by Apple before you run them the first time and periodically thereafter. This extends the protection from the app’s source to include automated checks for what’s in the app.
Data protections
macOS Catalina checks with you before allowing an app to access your data in your Documents, Desktop, and Downloads folders; iCloud Drive; the folders of third-party cloud storage providers; removable media; and external volumes. In addition, you’re asked before an app can perform key logging or capture a still or video recording of your screen.
Activation Lock
All Mac models with the Apple T2 Security Chip now support Activation Lock — just like your iPhone or iPad. So if your Mac is ever misplaced or lost, the only person who can erase and reactivate it is you.
Dedicated system volume
macOS Catalina runs in a dedicated, read-only system volume — which means it is completely separate from all other data and helps improve the reliability of macOS.
DriverKit and user space system extensions
Previously many hardware peripherals and sophisticated features needed to run their code directly within macOS using kernel extensions, or kexts. Now these programs run separately from the operating system, just like any other app, so they can’t affect macOS if something goes wrong.
Find My
Two great apps in one
Find My iPhone and Find My Friends are now combined in a single, easy-to-use app to help you locate the people and devices that are important to you.
Find offline devices
Locate a missing device even if it’s not connected to Wi-Fi using crowd-sourced location. When you mark your device as missing and another Apple user’s device is nearby, it can detect your device’s Bluetooth signal and report its location to you. It’s completely anonymous and encrypted end-to-end, so everyone’s privacy is protected.
Enhanced location notifications
Location notifications include the ability to schedule notifications for different days of the week, more useful place names, and enhanced privacy controls.
Approve with Apple Watch
View passwords
Anywhere you need to type your Mac password, such as viewing passwords in Safari preferences, you can now double-click the side button on your Apple Watch to authenticate on your Mac.
Approving app installations
Unlock a locked note, approve app installations, unlock settings in System Preferences, and modify root files, all with your Apple Watch.
Accessibility
Voice Control
Voice Control is a new way to fully control your Mac, iOS, and iPadOS devices entirely with your voice.
Voice Control improves on the existing Enhanced Dictation feature using the Siri speech recognition engine, so you get the latest advances in machine learning for audio-to-text transcription.
Add custom words
Whether you’re writing a biology report, filling out a legal document, or emailing about a favorite topic, you can add custom words to ensure that Voice Control recognizes the words you commonly use.
On-device processing
All audio processing for Voice Control happens on your device, ensuring that your personal data is kept private.
Rich text editing
Thanks to rich text editing commands, you don’t have to rehearse before you speak. Making corrections is quick and easy. You can replace phrases by name. Try saying “Replace I’m almost there with I just arrived.” Fine-grained selection also makes it simple to select text. Try saying “Move up two lines. Select previous word. Capitalize that.”
Word and emoji suggestions
If you need to correct a word, there’s a new interface just for that. Simply ask to correct a word, and you’ll be presented with a list of suggested replacements.
Seamless transitions from dictation to commands
Voice Control understands contextual cues, so you can seamlessly transition between text dictation and commands. For example, say “Happy Birthday. Tap send.” in Messages, and Voice Control sends “Happy Birthday” — just as you intended. You can also say “delete that”, and Voice Control knows to delete what you just typed.
Comprehensive app navigation
You can rely entirely on your voice to navigate an app. Comprehensive navigation is provided by navigation commands, names of accessibility labels, numbers, and grids.
Navigation commands
Navigation commands give you quick ways to interact with macOS and apps. You can open apps, search the web, open Spotlight, and more.
Names
You can easily navigate by telling Voice Control to select the name of an accessibility label for buttons, links, and more.
Numbers
Say “show numbers” to see numbers appear next to all clickable items onscreen. Use this to quickly navigate complex or unfamiliar apps. Numbers automatically appear in menus and whenever you need to disambiguate between items with the same name. Just say a number to click it.
Grids
If you ever need to touch a part of the screen that doesn’t have a control, use Grid overlays. Saying “show grid” superimposes a grid on your screen and allows you to precisely do things, like select, zoom, drag, and more.
Hover Text
Hover Text displays high-resolution zoom of text, text fields, menu items, buttons, and more in a dedicated window. Just press the Control key when hovering over text with your cursor, and a window with zoomed text appears alongside the standard interface — helping you stay contextually aware. Text is crisply displayed in a font and color of your choice. And you can interact with buttons and type right in the zoomed window.
Zoom Display
While using a second display, you can see the same screen up close and at a distance simultaneously. You can keep one monitor zoomed in and another at a standard resolution. Or keep a personal Mac zoomed in while giving a presentation.
Simplified tab navigation
VoiceOver users will enjoy simplified keyboard navigation that requires less drilling into unique focus groups. The Tab key more simply advances through selection of elements — such as window stoplights, toolbar buttons, and scroll bars.
Punctuation in iCloud
VoiceOver users often customize the way punctuation marks are spoken. These customizations are now stored in iCloud, giving you a consistent experience across macOS, iOS, and iPadOS.
Additional international braille tables
macOS Catalina adds more international braille tables and lets you quickly switch between them.
Improved VoiceOver support in Xcode
VoiceOver now reads aloud warnings, line numbers, and breakpoints in the Xcode text editor.
Display color filters
Users with color vision deficiencies can adjust display colors using new color filter options. Your Mac shifts the colors onscreen, helping you easily differentiate areas of confusion. And you can turn this preference on and off through the Accessibility Options pane using Command-Option-F5.
Tint your entire display
A new display option lets you tint your entire screen using a color of your choice. Some users may find that certain color tints help make text easier to read.
Apple ID Account Information
One place for your Apple ID account details
Now you can access all your important Apple ID account information right from System Preferences on your Mac.
Overview and helpful notifications
A new overview pane allows you to quickly review important tips and notifications to help ensure that your account is properly signed in and secure, and that all the features you expect are set up and working correctly.
Basic account and security details
Easily review account details such as your name, contact info, password, security details, payment and shipping info, and email newsletter preferences.
iCloud settings
Review and update your iCloud settings and manage or upgrade your storage plan anytime.
Media and purchases
Get easy access to your current subscriptions, past purchases, and account settings related to the App Store, iTunes Store, Apple Music, Apple Books, Apple News, Apple TV, and more.
Family Sharing
View which subscriptions you’re sharing, which services are enabled, who has Ask to Buy turned on, and more.
View all your devices
View a list of all the devices you’re signed in to with your account. Review device details such as last backup completed, Find My status, and more.
QuickTime Player
Picture in Picture (PiP)
With a single click in the navigation controller, you can play video in a resizable window that isn’t blocked by other windows, allowing you to watch while working on other things.
Enhanced Movie Inspector
The Movie Inspector pane shows you even more in-depth technical information about the currently open media file. See key details such as video color space, HDR format, bit depth, scale, and aspect ratio.
Open Image Sequence
Create an H.264, HEVC, or ProRes-encoded movie file by navigating to a folder of sequentially numbered images, then choosing your desired resolution, frame rate, and encoding quality.
Timecode support
When QuickTime Player opens a media file with embedded timecode, it shows the time information in the onscreen navigation controller.
Transparent video support
Transparency in ProRes 4444 files can optionally be preserved when exporting to the HEVC format.
Home
HomeKit Secure Video
With a home hub such as an Apple TV or HomePod, securely record video to iCloud when activity by a person, animal, or vehicle is detected by your HomeKit-enabled cameras. Choose to receive notifications when clips are recorded and view them in the Home app on your Mac. In the Home app, a timeline of recordings is available to play from iCloud. You can also share a recording, delete it, or save it to your Photos library.
Audio in scenes and automations
HomePod and AirPlay 2–enabled speakers can now play songs, playlists, and radio stations from Apple Music in scenes and automations with your other HomeKit accessories.
International Features
New multilingual setup for macOS
Choose your languages, including those for keyboard and dictation, in Setup Assistant, and customize your language preferences from the start.
New relationship labels in Contacts
Contacts now includes hundreds of new, more specific relationship labels to help you manage your contact list. Examples include “younger cousin” and “elder cousin.”
Cantonese keyboard predictions
The new Cantonese predictions for Traditional Chinese Cangjie, Sucheng, Stroke, and Handwriting keyboards bring more relevant character and emoji predictions to Cantonese users.
Improved Japanese predictions
A new neural language model takes words typed earlier in the sentence into account, so predictions are more grammatically consistent and relevant to the subject matter.
New fonts for Indian languages
Get 34 new fonts, including four system fonts and 30 document fonts, for languages like Gujarati, Hindi, Kannada, Odia, Punjabi, and many more.
New Indian English Siri voices
All-new Indian English male and female Siri voices allow Siri to be more natural and expressive.
New dictionaries
New dictionaries include Thai-English and Vietnamese-English.
You can now share folders with a private link. Anyone who has access can see the folder in iCloud Drive, add new files, and get the latest versions of files.
Restore from snapshot
If your third-party software is incompatible with an update you just installed, use macOS Recovery to restore from a snapshot of your computer taken right before the installation. macOS and all your apps will work just as they did before you installed the update.
Today Apple released macOS Mojave 10.14.6 Supplemental Update #3 and Security Updates 2019-005 for High Sierra 10.13 and Sierra 10.12.

The second one, which was released today is called macOS Mojave 10.14.6 Supplemental Update #2 (18G95). Apple does not call the updates #1 or #2 but I am so you can understand that two different Build Versions are out there.

MacOS Mojave 10.14.6 Supplemental Update was released today.
On the heels of the 2019-004 Security update rereleases, today Apple released one new update (Supplemental Update) and rereleased 10.14.6 updates.
1. 10.14.6 Supplemental Update – New
2. 10.14.6 Full Installer.app – Rereleased & Fixed
3. 10.14.6 Combo Update – Rereleased & Fixed
4. 10.14.6 Delta Update – Rereleased & Fixed
I say Rereleased & Fixed because the OS version is still 10.14.6, but the Build Version changed and now has the Supplemental update fixes built-in.
“Fixes an issue that may prevent certain Macs from waking from sleep properly.”
When the 2019-004 Security Update wake from sleep Kernel Panics started to happen, most of the reports were from 10.13 High Sierra. I did see a few from 10.12 Sierra and a few from 10.14 Mojave. The issue was coming mostly from users reports on Apple’s Discussion Forum, Reddit, MacRumors & Emails / Comments to me.
Is this issue the same as the 2019-004 Sleep/Wake issue?
I’m not sure if Mojave had the same issue, but it sure looks like it. I tried many times to reproduce this issue but couldn’t on multiple Mac models. Most likely, this means that a very particular software setup caused the problem.
New and Previous Build Versions of 10.14.6
July 22nd version of 10.14.6 = (18G84)
August 1st version of 10.14.6 = (18G87)
Download Links for the new 10.14.6 Updates
10.14.6 Delta Update – Still old July 22nd version do not downloadfrom apple.com/downloads until the page is updated!!!
10.14.6 Combo Update – Still old July 22nd version do not downloadfrom apple.com/downloads until the page is updated!!!
Do I need to reinstall the new 10.14.6 update? & Which update do I need if I’m on a previous version of 10.14?
1. Do I need to reinstall the new 10.14.6 update? – The answer is it depends!
10.14.6 = New Supplemental Update
10.14.5 = New Delta Update
10.14.0 – 10.14.4 =New Combo Update
2. Which update do I need if I’m on a previous version? – The above chart now answers this one ^
If I deployed/cached the old 10.14.6 Installer.app for upgrades, do I need to redeploy?
Do I have to replace my deployable 10.14.6 Installer.app? – YES!!!
If you deployed the old version of the 10.14.6 (18G84) Installer, you should update it to the new (18G87). If you don’t your users may be stuck with a sleep-wake issue and have to install the Supplemental Update to fix it!
What if I cached the old 10.14.6 Update to all my systems?
What will happen if I already cached the old version of 10.14.6 to my users?
My guess was once the Mac reached out to software update it would find the new version of 10.14.6 and download it. Pcrandom ran this test and found that this is, in fact, true with one catch. The old version was still in /Library/Updates.
“I am seeing some Macs that have both copies when running du -hd1 /Library/Updates:“
2.8G /Library/Updates/041-88928
2.8G /Library/Updates/041-94407
202M /Library/Updates/041-86543
5.9G /Library/Updates
I wanted to test installing the new update to see if the old one was removed, but we did not get a chance to test.
Keep in mind that in 10.14 /Library/Updates is SIP protected, so you will not be able to delete the old update if it remains!
Softwareupdate knows all.
If you are using softwareupdate to deploy updates to your Macs, you will be fine. It will let you know which update you need to install. If you want to check just run a quick softwareupdate -l and you will see what’s available for your particular situation.
No, we didn’t time travel 3 weeks into the past. A new version of macOS Mojave 10.14.5 (18F2059) was released yesterday.
Today for some reason and maybe for the first time, Apple released an update to a previous full installer release. The previous build version macOS 10.14.5 (18F2058) was released on July 9th and covered the new 2019 13″ MacBook Pro and 2019 MacBook Air. Apple released MacOS Mojave 10.14.6 (18G84) on July 22 and unified all builds. That means you can install 10.14.6 on any Mac.
I honestly have no clue! Again since 10.14.6 is a unified build we should have no need for a updated installer of a previous build. A user in MacAdmins Slack mentioned that this might be an update to 2058 for the factory restores. If that was the case why was it just now released and not 3 weeks ago? Or maybe this build version was for Internet recovery or something, again though this does not make any sense since agin 10.14.6 is unified.
This page will be updated when new 10.15 new information or links come in.
WWDC 2019
WWDC is here again! On Monday, June 3rd, 2019 Apple Released macOS 10.15 Catalina. The first question MacAdmins have is, what changes do I need to know about and how will they affect my macOS deployments? Hopefully, I will help you answer that question with this article. I am following the same format as my previous Notarization Index post. MacAdmins have told me they really liked having all the important information on a topic in one place. MacAdmins like Robert Hammem, Charles Edge and Rich Trouton are already crushing it by gathering information on all the latest changes. In this post, I will keep an updated index of changes and links to keep you informed of the latest public information regarding macOS 10.15 Catalina.
zsh is now the default shell instead of Bash – Starting with the macOS Catalina beta, your Mac uses zsh as the default login shell and interactive shell. You can make zsh the default in earlier versions of macOS as well. https://support.apple.com/en-us/HT208050
Python 2.7 is deprecated.
Scripting language runtimes such as Python, Ruby, and Perl are included in macOS for compatibility with legacy software. Future versions of macOS won’t include scripting
language runtimes by default, and might require you to install additional packages. If your software depends on scripting languages, it’s recommended that you bundle the runtime within the app.
Use of Python 2.7 isn’t recommended as this version is included in macOS for compatibility with legacy software. Future versions of macOS won’t include Python 2.7. Instead, it’s recommended that you run python3 from within Terminal.
32 Bit applications are now deprecated
If you still have older software that is 32bit they will NOT load.
Profile installation using the profiles command-line tool will be deprecated in future releases of macOS.
New Activation Lock Option for T2 Macs. – All Mac models with the Apple T2 Security Chip now support Activation Lock — just like your iPhone or iPad. So if your Mac is ever misplaced or lost, the only person who can erase and reactivate it is you. More info: forums.developer.apple.com/message/363374
New Read-Only Filesystem Partition. User data is stored on the 2nd partition “Macintosh HD — Data”. MacOS Catalina runs in a dedicated, read-only system volume — which means it is completely separate from all other data, and nothing can overwrite your critical operating system files.
NOTE: Beta 1 – The Macintosh HD Read Only Partition is writeable
If you want to enable read only you have to place a file in the root of the drive.
sudo touch /.rootro
Then reboot to enable read-only mode.
Verify by trying to create /.rootro2
sudo touch /.rootro2
You should get touch /.rootro2: Read-Only file system
NOTE #2: Beta 2 – The Macintosh HD Read Only Partition is now protected by default
When checking on beta 2 you should get touch /.rootro2: Read-Only file system from running sudo touch /.rootro
TCC now covers the users Desktop & Documents Folder, cloud and external drives. – macOS Catalina checks with you before allowing an app to access your data in your Documents, Desktop, and Downloads folders; iCloud Drive; the folders of third-party cloud storage providers; removable media; and external volumes. In addition, you’re asked before an app can perform key logging or capture a still or video recording of your screen.
User Space System Extensions and SDriverKit. – Previously many hardware peripherals and sophisticated features needed to run their code directly within macOS using kernel extensions, or kexts. Now these programs run separately from the operating system, just like any other app, so they can’t affect macOS if something goes wrong.
Marzipan is now Project Catalyst – Allowing iOS apps to be ported over to macOS using Xcode.
lpadmin: Printer drivers are deprecated and will stop working in a future version of CUPS. CUPS printer drivers and backends are deprecated and will no longer be supported in a future feature release of CUPS. Printers that do not support IPP can be supported using applications such as ippeveprinter.
Enterprise Connect is transforming from an app into a new Apple first-party Single Sign-On macOS extension. This new extension delivers improved Kerberos support on macOS. Developers can now build SSO extensions that integrate with websites or native apps and support identity providers like Microsoft Azure AD, Okta and Ping. 10.14 and under will still support the old application for 1 year.
SecureToken BootStrap or Active Directory BootStrap Tokens will be a new way for Active Directory Accounts to get a SecureToken. This will need to be applied from a UAMDM via profile. This new feature will be for the 2nd 3rd or 4th Active Directory SecureToken User only, NOT the first user to log into the system.
4. Security Changes
Notarization is now enforced for all packages, applications and installers built or after June 1st 2019EDIT: See Update Below.
This includes Kexts, but enforcement was already put into place on macOS Mojave 10.14.5.
Gatekeeper Improvements – Gatekeeper will ensure that all new apps you install — from the App Store or the internet — have been checked for known security issues by Apple before you run them the first time and periodically thereafter. This extends the protection from the app’s source to include automated checks for what’s in the app.
UPDATE: 10/03/19 – Apple has changed this and Kexts will NOT require a reboot! – Kernel Extensions (Kexts) now require a reboot to load – Installing third party kernel extensions now requires that you restart your Mac before they’re permitted to load.

FileVault & fdesetup changes – FileVault FV2 now requires User-Approved MDM Enrollment or UAMDM. You also can’t pass username/password authentication to fdesetup enable. These changes may break existing scripts, workflows or MDM agents. Be sure to check man fdesetup in 10.15 beta to read more about the new Authorization policy. You will need to follow at least one path to use fdesetup to enable FileVault Encryption.

7. MacAdmins Blog Links
This list is specifically for MacAdmins. This will be an ongoing list of articles and posts that will help you learn the latest 10.15 changes.
The macOS 10.15 SDK provides support for developing apps for Macs running macOS Catalina 10.15. The SDK comes bundled with Xcode 11 beta available from Beta Software Downloads. For information on the compatibility requirements for Xcode 11, see Xcode 11 Beta Release Notes.
Installing third party kernel extensions now requires that you restart your Mac before they’re permitted to load.
Deprecations
macOS frameworks are now thinned for the x86-64 architecture. Apps that execute i386 code now fail with the EBADARCH error code. The remaining stub frameworks are nonfunctional and exist only for compatibility purposes.
9. macOS Catalina 10.15 Beta 1 Known Issues
Migration Assistant is currently unable to correctly migrate data from a Mac running macOS 10.15 to another Mac running macOS 10.15.
WarningYour Secure Token might be lost if FileVault is enabled on a non-APFS formatted volume while upgrading to macOS 10.15. You might be able to work around this by disabling FileVault before upgrading to macOS 10.15, then reenabling FileVault once the upgrade has completed.
During installation of macOS 10.15 you might be prompted to enter your administrator password multiple times to allow installation to proceed.
macOS 10.15 cannot be installed onto an encrypted volume unless it is already in the APFS format.
During upgrades to macOS 10.15, files and folders stored at the root-level of a volume are moved aside to /Library/SystemMigration/History/Migration-UUID/QuarantineRoot/.
If your Mac currently has macOS 10.10 or earlier installed, you must first upgrade to macOS Mojave 10.14 before upgrading to macOS 10.15.
The Install macOS 10.15 app might quit unexpectedly when run on macOS 10.9.
On Macs with the Apple T2 Security Chip, if you’ve used Startup Security Utility to lower Secure Boot to Medium Security or No Security, you’re currently unable to modify Secure Boot settings after upgrading to macOS 10.15.
Workaround: Set Secure Boot to Full Security before upgrading to macOS 10.15. Alternatively, disabling and reenabling FileVault might resolve the issue.
Some apps might not automatically relaunch after installation or updating and must be manually relaunched.
On Macs with the Apple T2 Security Chip, VoiceOver is currently unavailable while in macOS Recovery.
When using the SecureEnclave API with access control set on keys, users might not be prompted to authenticate. This might cause subsequent operations requiring authentication to fail.
Volume replication shouldn’t be used with Fusion volumes, either as a source or destination.
