Apple Warns Users macOS Will End Support for 32-Bit Apps

Apple has made clear for years now that its future fits squarely in the 64-bit realm.

There's no harm in using 32-bit apps, but Apple wants developers to utilize modern hardware features that only work with 64-bit apps.

Apple has not said exactly when it will stop supporting 32-bit apps, and it's likely to still be some way off in the future - but that day is still drawing closer. A one-time alert has been pushed out to those running macOS 10.13.4 which will trigger once users launch a 32-bit app. This was the statement it released for the goal: "The last macOS release to support 32-bit apps without compromise is macOS High Sierra". But for those who have been using Macs for years, download software from outside the Mac App Store, or perhaps have built their own apps, there's a chance that at least some of the programs on their computers are running in 32-bit.

Starting on April 12th, macOS users will begin receiving messages indicating that apps installed on their system are 32-bit, and will require an update.

"The 64-bit transition for macOS and macOS apps is still underway, so final transition dates have not yet been established".

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).

Apple warned developers back in June that a future update to macOS after the current High Sierra update would not run 32-bit apps "without compromise", and 64-bit has been required for both app submissions and app updates to the Mac App Store since January 1. When comparing the two, 64-bit is more efficient for it can access more memory and harness the power of newer technologies.

Users can check which apps are 32-bit or 64-bit by going to About this Mac and pressing System Report, scrolling down to Software and then selecting Applications.

Nevertheless, one thing is sure, that Apple is serious about phasing out the 32-bit apps soon. Also, the company is already through the same transition to 64-bit in the iOS.

If the processor is an Intel Core Solo or Intel Core Duo, it's 32-bit only. Thereafter, the company made 64-bit mandatory with the iOS 11. There could be one on the developer's website, or in Apple's App Store. The pop-up says that the app needs to be updated. As for macOS, it is optimized to work with 64-bit applications.
