macOS Recovery​

Deprecations​

Maps​

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​

Safari​

Known Issues​

  • Safari toolbar vibrancy and background color might adversely affect the legibility of tab buttons in the tab bar. (80417925)

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​

    Workaround: Update to Xcode 13 to continue developing on macOS Monterey.
 
I've been using MacOS Monterei beta 6 and it has been a blast! Works flawlessly with iOS 15 and AirPlay to Mac is awesome though Netflix doesn't work on Airplay to Mac for some reason but all other streaming services work fine!
