As of iPadOS 27, if you have multiple windows open while AirPlaying (whether or not Stage Manager is on), tapping on anything other than the presenting app will snap the external display into showing your whole iPad screen. This means that my students see all my notes on who I want to call on, or poll results that should be hidden from them. They also get distracted from what we’re learning by all these jarring windows popping up and disappearing. If you’re presenting at a big conference, it’s extremely embarrassing.

As for what the behavior should be, I’m not a developer, but here’s a proposal: if you’re using an app that is in presenter mode (e.g., PowerPoint playing a presentation, or a GoodNotes document open), it should always get precedence on the external display, until that presentation gets stopped, the document is closed, or the app is quit.

Apple recently updated its tablet operating system, but the new version is causing some headaches for teachers and professionals.

According to Apple’s release notes, iOS 27.0.1 addresses an issue that could cause Face ID not to work properly on the iPhone 18 Pro.

Some iPhone 18 Pro users have complained that authentication can fail to work for things like unlocking a locked app. In some cases, the device freezes up and then reboots. Other users have seen a “ Face ID is Not Available” message when attempting Face ID setup, and others have experienced issues with the Require Attention for Face ID setting.

Juli Clover:

Apple’s security support pages say there was a CoreGraphics out-of-bounds write issue that could be exploited with a maliciously crafted file, allowing for arbitrary code execution. […] Apple says the flaw was exploited in an “extremely sophisticated attack” on targeted individuals running older versions of iOS.

Absolutely shocking to me how this is always my experience with Apple’s search functionalities

Just a matter of days after iOS 27 has been released to the public, people have already discovered a way to temporarily brick your phone with a quick series of swipes on the home screen. And it’s starting to going viral on social media as some kind of iPhone prank to do on your friends.

Luckily, it is only a software soft-lock and you can easily get out of this temporarily bricked state by force rebooting your phone.

It will apparently be fixed in iOS 27.2.
