13. macOS Monterey Release Notes

https://developer.apple.com/documentation/macos-release-notes/macos-12-beta-release-notes

Overview

The macOS 12 SDK provides support to develop apps for Mac computers running macOS Monterey 12. The SDK comes bundled with Xcode 13 beta 5, available from Beta Software Downloads. For information on the compatibility requirements for Xcode 13, see Xcode 13 Release Notes.

AppKit

• See AppKit Release Notes for macOS Monterey 12 Beta.

Displays Preferences

Known Issues

• There might be issues with wakeup when dual monitors are connected. (79839446)Workaround: Connect the power adapter that came with the Mac.

CoreData

Known Issues

• NSExpression immediately forbids certain operations that have significant side effects, like creating and destroying objects. Additionally, casting string class names into Class objects with NSConstantValueExpression is deprecated. (84017178)Workaround: Pass temporary objects to NSExpression in the context parameter of expressionValueWithObject:context:, or with NSPredicate as the substitutionVariables parameter of evaluateWithObject:substitutionVariables:. You can create a derived predicate with all the substitution variables replaced (bound), using withSubstitutionVariables(_:) on an existing NSPredicate so that code using the object can continue to use a simple evaluate(with object: Any?) invocation.

iCloud

Known Issues

• Legacy Contacts has been removed from macOS Monterey 12 beta 5 and will return in a future release. (81292890)
• Custom Email Domain addresses that are associated with a separate iTunes account can’t be configured. (82358431)

Mac Catalyst

Known Issues

• Setting the title color of a UIButton doesn’t work regardless of whether you use baseForegroundColor or titleColorForState:. (76566253)

Maps

Deprecations

• MKPinAnnotationView and MapPin are deprecated in this beta. (78536295)

Known Issues

• Rounded building corners might disappear. (80468151)

Networking

Deprecations

• Support for cleartext HTTP URL schemes for Proxy Automatic Configuration (PAC) is now deprecated. Use only HTTPS URL schemes for PAC. This affects all PAC configurations, including, but not limited to, configurations set via Settings, System Preferences, profiles, and URLSession APIs such as connectionProxyDictionary and CFNetworkExecuteProxyAutoConfigurationURL(_:_:_:_:). If you configure a cleartext HTTP PAC URL, the system may upgrade it to HTTPS during PAC file loads. Web Proxy Auto-Discovery (WPAD) Protocol via DNS isn’t affected. Dynamic Host Configuration Protocol (DHCP) Option 252 WPAD may attempt to upgrade cleartext HTTP URLs to HTTPS during PAC file loads. (61981845)

Python

Deprecations

• If an app uses Python 2.7, macOS now triggers an alert indicating that the developer must update the app to ensure it will work in future versions of macOS. (80221011)

RealityKit

Known Issues

• The StreamingInput init on PhotogrammetrySession isn’t supported. (78838906)

SharePlay

Deprecations

• SharePlay development in macOS Monterey beta 6 and upcoming beta releases requires the installation of an updated SharePlay Development Profile. This profile enables successful creation and reception of GroupSessions via the Group Activities API in iOS 15, iPadOS 15, and tvOS 15 beta 7, as well as macOS Monterey beta 6. (81900143)

Swift

Known Issues

• Applications linking to RealityKit with the iOS 15 or macOS 12 SDKs will fail to launch on a previous OS. (79584511)Workaround: Add OTHER_LD_FLAGS = -weak_framework RealityFoundation to your Xcode Project settings to allow running RealityKit apps on an older OS.

SwiftUI

Deprecations

• controlProminence is deprecated. Use the new .borderedProminent ButtonStyle instead. (78908460)
• Fn (Function) shortcut modifier is deprecated and reserved for system usage. (78627099)
