Don’t Update MacOS 10.13.4 If Using Duet Display

With all the excitement caused by yesterday ‘s iOS 11.3 release , you may not have noticed that Apple has also released macOS 10.13.4 globally. The latest Mac update includes a number of small fixes with a focus on “ stability, performance, and security, ” but if you’re using Duet Display, you should avoid the newest version of macOS at all costs.

Duet Display, the popular app that turns your iPad into a second screen for your Mac, announced this week that a bug in Apple’s update is blocking the software. The company has no solution at this point, instead suggesting sticking to macOS 10.13.3 until a fix is ​​available.

If you’ve never heard of Duet Display, the app is definitely worth a try – assuming you have an iPad handy and haven’t updated to macOS 10.13.4 yet. All you need is a wired connection and you can turn your tablet into a fully functional macOS secondary screen. The app also adds a MacBook Pro-style touchbar to your iPad when it’s connected, and if your iPad supports Apple Pencil, it works in Duet Display as well.
