Apple Begins Notifying macOS Users That 32-bit App Support Is Ending

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.

Apple's warnings for the Mac users will pop-up once a user opens a 32-bit app on the macOS High Sierra 10.13.4. Also, even Apple hasn't moved all its apps to 64-bit. The statement that High Sierra is the last version to support 32-bit "without compromise" suggests some stop-gap measure in the next version of macOS.

Apple has launched a campaign to inform users of the imminent cessation of support for 32-bit programs. Make sure future releases of your app are 64-bit compatible by using new diagnostic tools in Xcode 9.3 beta and testing on macOS 10.13.4 beta.

For now, it can be assumed that the 32-bit apps will run for the Mac users. Still, when the big day finally rolls around, there will nearly certainly be complaints nonetheless.

If you're concerned about all this and want to know exactly which apps you're running now deliver 64-bit support, the folks over at AppleMust have made a handy guide to find out. "The alert box's message reads: "'App' is not optimized for your Mac.

Apple is now pushing out notifications warning users that 32-bit app support will be dropped in an upcoming version of macOS.

Launching a 32-bit app will obviously trigger Apple's warning, but there's a much easier way to get a full list of all the 32-bit apps you have.

Today Apple started its push of 64-bit apps. That difference in stance is largely the result of Redmond having a vastly larger legacy installation base than Cupertino, but it means Mac users need to keep a slightly closer eye on apps they use. For business users, the Blue Jeans and Cisco WebEx teleconferencing clients are still only available as 32-bit apps.

Similar to Microsoft and Windows 10, Apple has been slowly transitioning to 64-bit hardware and software over the course of the last decade. For this, one needs to go to the Apple menu and select This Mac, and then click the System Report button. "When you select an individual application, you will see a field titled "64-bit (Intel)".

Apple started that process in 2013 with its first 64-bit mobile processor, the A7. "Yes" indicates 64-bit; "No" indicates 32-bit. Presently, the App Store does not accept submissions of 32-bit apps for macOS.
