Mac 32-bit Support Ending, Users Being Warned

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. 64-bit apps are also capable of utilizing more memory than 32-bit ones, meaning they are able to perform faster, and much more smoothly. "This gives users advance notice that they are running 32-bit software, which will not be compatible with macOS in the future", Apple says in a new support note. To help explain what is going on, the message features a Learn More button. The same support page linked to above states that "all future Mac software will eventually be required to be 64-bit". Still, when the big day finally rolls around, there will nearly certainly be complaints nonetheless. Though the company hasn't been equally aggressive with the Mac users yet, given the warnings have already started it, won't be long before 32-bit takes its last breath on the Mac's as well.

Apple hasn't announced a cut-off date for 32-bit apps but High Sierra will be the last version of macOS to support the 32-bit apps "without compromise".

Developers first got word that 32-bit support would be phased out back in June 2017.

Apple's support document also includes a new "frequently asked questions" section that addresses concerns like potential data loss and 32-bit app support on macOS High Sierra, according to the website 9to5 Mac. From the system report, scroll down to Software, then select Applications. 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. The technologies that define today's Mac experience-such as Metal graphics acceleration-work only with 64-bit apps. If an app shows "No", that means it's 32-bit and needs to be updated.

Similar to Microsoft and Windows 10, Apple has been slowly transitioning to 64-bit hardware and software over the course of the last decade. "When you select an individual application, you will see a field titled "64-bit (Intel)".

What it isn't doing, however, is telling anyone when the 32-bit/64-bit split will actually arrive. The A7 chip, which powered the 2013 iPhone 5S, was the first 64-bit mobile processor. The latest beta of watchOS 4.3.1, which is sort of the watchOS equivalent of iOS 11.4, warns you when you try to launch an out-of-date app.
