What’s New in macOS Big Sur 11.1 Beta (20C5048k)?

Today Apple released macOS Big Sur Beta 11.1 Beta (20C5048k) to Developers

MacOS Big Sur 11.1 Beta was released on November 17th, 2020. The release comes on Apple Silicon M1 Mac Day! One big change is the version number.

macOS 11.1

This means that instead of getting 11.0.2, we will get 11.1. Next year it seems we will get macOS 12. This is a big change and it looks like Apple is trying to follow the iOS and iPad version system.

macOS Big Sur 11.0.1 Beta 2 Release Candidate (20B5022a) Release Notes

Overview

The macOS 11.1 SDK provides support to develop apps for Macs running macOS Big Sur 11.1 beta. The SDK comes bundled with Xcode 12.3 beta, available from Beta Software Downloads. For information on the compatibility requirements for Xcode 12.3 beta, see Xcode 12.3 Beta Release Notes.

Accessibility

Known Issues

• InfoVox voices from AcapellaGroup aren’t currently supported by VoiceOver. (64880915)Workaround: Choose an alternate voice such as Alex or Siri.

Mac Catalyst

Known Issues

• Full-screen mode might zoom content beyond the borders of your display. (70103920)
• The zoom-to-fit state isn’t currently preserved across app launches. (70885745)
• When you present a view controller with page sheet or form sheet presentation style, the size of the view controller’s root view is, by default, determined by the value returned from the presented view controller’s preferredContentSize method and the view is not resizable. You can arrange for the presented view controller to be resizable by using Auto Layout to specify the maximum and minimum sizes of its root view. To enable this, set the canResizeToFitContent property of the application’s main window to YES. One way to do this is to override the willMove(toWindow:) or didMoveToWindow() methods of a view in the main view controller. (65254666)For example:- (void)willMoveToWindow:(UIWindow *)newWindow { [super willMoveToWindow:newWindow]; newWindow.canResizeToFitContent = YES;}

Software Update

Known Issues

• A known issue prevents booting back into macOS Big Sur 11.0.1 after installing macOS Big Sur 11.1 beta onto a separate volume on Macs with Apple silicon. (71353899)
• Using either macOS Recovery or a bootable installer to reinstall macOS Big Sur 11.1 beta on Macs with Apple silicon isn’t currently supported. (71353899)Workaround: Use the Restore option in the latest version of Apple Configurator 2 running on a secondary Mac. Note that this will erase all content from the storage media on the Mac you’re restoring.
