If you’re running Universal Control, make sure your macOS and iOS versions jive.
After a quiet few weeks, Apple on Tuesday released the first developer and public betas for macOS Monterey 12.4. It likely mostly includes bug fixes and security updates, though it’s possible that it also includes hidden references to new hardware releasing at WWDC in early June.
Developers can get the update through the Apple Developer website, or, if you are running the betas, by performing a Software Update.
Version 12.4 includes an important note for Universal Control. If you install 12.4, all devices that you want to use with Universal Control must also be updated to the latest betas. Apple also released the iPadOS 15.4 beta this week, so any iPad needs to use that version and other Macs you want to use with Universal Control must be running 12.4. According to Apple, Universal Control in 12.4 is not compatible with macOS 12.3 and iOS 15.4. It wasn’t immediately clear why or whether there are any visible changes.
