Apple To Mac Users: We Will End Support For 32-bit Apps

The company has now started informing Mac users that 32-bit app support is going to end in the near future. "They say "[app name] is not optimized for Mac" and they only appear once so as not to be a pest, but it's a gentle nudge for users and developers alike that the future for Apple is very much going to be based on 64-bits.

macOS High Sierra doesn't actually change anything about the way 32-bit apps run on the Mac, but Apple is encouraging users of 32-bit apps to seek out 64-bit versions or contact developers before the transition is completed. Apple chose to ditch support for 32-bit devices with iOS 11 and it promised to make a similar move for Mac apps as well. Clicking on the former will load a support document that details the long process of shifting from 32-bit to 64-bit computing.

While Apple hasn't detailed exactly what "without compromise" means, it's my understanding that 32-bit apps will run on the successor to High Sierra due this fall... just with some sort of undefined compromise. This may take the form of a "compatibility mode" which will be enough to send shivers down the spine of anyone who used Windows Vista.

Further, the support page also explains to the users the advantages of using the 64-bit apps.

All modern Macs include powerful 64-bit processors, and macOS runs advanced 64-bit apps, which can access dramatically more memory and enable faster system performance. However, High Sierra is indeed the last update to support 32-bit. That, together with security concerns, are the two most likely reasons for cutting off support for apps made to run on an operating system only a few years old. At the same time, it'll be easier for Apple to maintain the apps. "The developer of this app needs to update it to improve its compatibility." . The same support page linked to above states that "all future Mac software will eventually be required to be 64-bit".

Nevertheless, one thing is sure, that Apple is serious about phasing out the 32-bit apps soon.

OS X Leopard (10.5), released in October 2007, was the first version to introduce full support for 64-bit apps.
