How to Find Out Which Mac Software Needs Updating

Q. If Apple is ditching 32-bit apps for its iOS system this fall, are they doing the same thing for 32-bit apps on OS X? How can I tell if I have any 32-bit apps on my Mac?

A. Apple has been building operating systems and Mac hardware with 64-bit processors for years now, and is indeed moving away from 32-bit desktop software too. (The terms “32-bit” and “64-bit” refer to the more technical side of computing; a basic thing to remember is that 64-bit systems are newer and can process more data faster.)

At this year’s World Wide Developers Conference in June, the company announced that all new programs submitted to the Mac App Store starting in January 2018 must have 64-bit support.

With all apps in its store written for 64-bit systems, Apple will begin to phase out its own support of 32-bit programs.

Apple also announced the macOS High Sierra operating system previewed at the conference this summer will be the last system to run 32-bit apps “without compromise.” The final release of High Sierra is expected this fall.

In the System Information area of your Mac, you can see which of your installed apps are 32-bit versions and which ones are 64-bit. To get there, go to the Apple Menu in the top-left corner of the screen, select About This Mac and click the System Report button in the box. (As an alternative shortcut, hold down the Option key when you click the Apple Menu and choose System Information.)

On the left side of the box, find Software and click Applications. The Mac may take a few minutes, but it eventually rounds up a list of programs…
