Apple Now Informing Mac Users About 32-Bit App Support Ending

Apple has begun notifying macOS users of coming 32-bit app incompatibility

Apple has begun notifying macOS users that 32-bit applications will not work on future versions of the operating system.

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. Apple included a similar alert dialogue on 32-bit iOS apps with iOS 10.3 before requiring 64-bit support to launch on iOS 11 past year. Last summer, the company was users that 32-bit apps would be disabled in a post-High Sierra update. Apple has warned developers that macOS High Sierra will be the last version to support 32-bit at all. The alert will appear once per app when a user launches 32-bit software for the first when running the current macOS version. However, High Sierra is indeed the last update to support 32-bit.

Once this transition is completed, MacOS will join iOS which is already pure 64-bit.

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.

"To ensure that the apps you purchase are as advanced as the Mac you run them on, all future Mac software will eventually be required to be 64-bit", the support page says. Then scroll down to Software and select Applications. Clicking on the former will load a support document that details the long process of shifting from 32-bit to 64-bit computing. However, it is believed that the 32-bit apps won't work as well as they use to before. If this listing says Yes, then the app is a 64-bit app. Apple usually unveils the next major versions of its operating systems at that event, so it makes sense that Apple could provide more details then.

Nevertheless, one thing is sure, that Apple is serious about phasing out the 32-bit apps soon. There could be one on the developer's website, or in Apple's App Store.

If you're using an old Apple Watch app that hasn't been updated in a while, you might run into some problems when watchOS 5 lands (likely sometime this autumn). In case of macOS, the company already stopped accepting similar apps to Mac App Store.

Making the shift on the desktop is much more cumbersome than on the mobile devices for two reasons, according to TechCrunch.

This break with compatibility for the very first version of watchOS is an indication that Apple intends to keep rushing forward with Apple Watch, and that watchOS 5 will be more than just a minor upgrade.
