64-bit apps

Mac|Life - - FEATURE -

If you spend a lot of time us­ing an iPhone or iPad, and you hap­pen to have a large col­lec­tion of apps and games, chances are iOS 11 thinned your col­lec­tion some­what. This was due to Ap­ple end­ing sup­port for 32-bit apps. Sadly, it’s not vi­able for ev­ery de­vel­oper to up­date their apps, so some sim­ply don’t work on iOS 11.

It looks like a sim­i­lar sit­u­a­tion will af­fect the Mac at some point. At WWDC 2017, Ap­ple said all apps and games submitted to the Mac App Store from Jan­uary 2018 will have to be 64-bit. Up­dates to ex­ist­ing apps must com­ply by July.

To check your apps, go to  > About This Mac, click Sys­tem Re­port, and se­lect Ap­pli­ca­tions in the side­bar. Click the “64-bit” header to sort the list so 32-bit apps are at the top, take notes, then con­tact rel­e­vant de­vel­op­ers to see if they plan to in­tro­duce 64-bit ver­sions for the next macOS.
