macOS Big Sur 11.1 Beta 2 (20C5061b)

Today Apple released macOS Big Sur Beta 11.1 Beta 2 (20C5061b) to Developers

MacOS Big Sur 11.1 Beta was released on December 3rd, 2020. The release comes about two weeks after Big Sur 11.1 Beta 1.

NOTE: The 2013-14 13″ MacBook Pro BoardID (Mac-189A3D4F975D5FFC) is not in 11.1 Beta 2. This means that Apple could be still working on a fix for this issue. You can read more about it in the link below.

macOS Big Sur 11.1 Beta 2 (20C5061b) Release Notes

Overview

The macOS 11.1 SDK provides support to develop apps for Macs running macOS Big Sur 11.1 beta 2. 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

Resolved in macOS Big Sur 11.1 beta 2

  • VoiceOver now supports InfoVox voices from AcapellaGroup. (64880915)

AppKit

Known Issues

  • Certain NSToolbar controls unexpectedly draw a background highlight when you click or roll over them. (71592628)

Mac Catalyst

Known Issues

  • 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;}

Resolved in macOS Big Sur 11.1 beta 2

  • Full-screen mode in a non-resizable iOS & iPadOS app now works as expected. (71440982)
  • The zoom-to-fit state is now preserved across app launches. (70885745)

Software Update

Resolved in macOS Big Sur 11.1 beta 2

  • 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 is now supported. (71353899)
  • Using either macOS Recovery or a bootable installer to reinstall macOS Big Sur 11.1 beta on Macs with Apple silicon is now supported. (71221267)
