Today Apple released macOS Big Sur 11 – 10.16 Beta 2 (20A4300b) to Developers

MacOS Big Sur 11 Beta 2 (20A4300b) was released today, two weeks after the WWDC20 Keynote introduction. During the Big Sur beta release cycle, only the current beta patch notes are available. When a new beta is released the previous patch notes are overwritten. I compare both sets of release notes so I find the changes.

UPDATE 7/08/20 – Apple has not yet released a Beta 2 version for the DTK Apple Silicon Mac Mini yet.

UPDATE 7/08/20 – I’m starting to see issues with getting Beta 2 to show up in Software Update. – mrmacintosh.com/big-sur-11-beta-not-showing-up-in-software-update-troubleshooting/

UPDATE 7/07/20 – Keep an eye on my Big Sur Need to Know changes article. I will be constantly updating it as new info comes in. mrmacintosh.com/macos-big-sur-11-0-updated-index-of-need-to-know-changes-links/

Report Bugs NOW!

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 Beta 2 (20A4300b) 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.

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

  • 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:
    1. Remove the extension from /Library/Extensions.
    2. Boot to macOS Recovery.
    3. Run Terminal.
    4. Enter the command kmutil trigger-panic-medic --volume-root /Volumes/<YourVolumeName>.

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

Vision

Known Issues

  • The NSSecureCoding implementation of VNRecognizedPointsObservation currently causes initWithCoder: to fail. (63681919)

Deprecations

  • The VNIdentifiedPointsObservation class is deprecated. Use VNRecognizedPointsObservation instances instead. (63690311)

Weather

Known Issues

  • The Weather widget may unexpectedly display weather for Cupertino instead of your current location. (64118168)

Xcode Previews

Resolved Issues

  • 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)
