One of the features of macOS Catalina is a new one called Sidecar. It basically allows macOS users to take an iPad and turn it into a secondary display for their MacBook laptops. It sounds pretty useful, especially for users who have had to rely on third-party alternatives for this.
However, there will be some limitations. The Verge found an Apple white paper that reveals that Sidecar won’t work on all MacBook laptops. It looks like only the newer MacBook models will be compatible.
If you own a MacBook from 2016 or later, a MacBook Air from 2018 or later, or a MacBook Pro from 2016 or later it’s all good. This could be due to a hardware limitation where it will require Intel’s Skylake CPUs or newer in order for it to function properly. It cannot be confirmed if that is truly the case here, but it does sound correct.
Sidecar will also work on non-MacBook computers as well, as long as they are iMac Pros, the 2019 Mac Pro, iMacs from 2015 or later, or Mac minis from 2018 or later, all of which coincidentally enough are powered by Skylake chipsets. So it is a very cool feature, but it has some sad limitations.
