Use it to scan your system and then when it’s finished, in the results window, click Minor Issues at the left, and select the Review button alongside the 32-Bit Apps heading. For this you can use the latest version of the Etrecheck system information tool. A better method would be to scan the system for 32-bit apps and produce a list. This takes time, though, and it’s not always easy to understand which app is being talked about. Look at the heading 64-Bit (Intel) beneath. In the app window that appears, click the Applications heading under the Software heading at the left, and then select any app you’re interested in within the list at the top right.

Just hold down the Option key and click the Apple menu at the top left of the screen, then select the app’s entry at top of the menu. One way to check is to open System Information, which is one of the macOS built-in diagnostic tools. A new column will be added at the right of the column listed, but you should now be able to use it to order the list by 32- and 64-bit apps.īut what about finding what 32-but apps lurk on your system? Surely you don’t have to run each and every one to find out which are 32-bit? Then right-click on the column headings and select Kind from the list. You can see what apps currently running on your system are 32-bit by opening Activity Monitor (you’ll find it in the Utilities folder of the Applications list in Finder), and then ensuring the CPU tab is selected. This also means that apps have to be 64-bit to run in the next version of macOS. Much has been written about the up-coming switch to a 64-bit-only macOS (see Apple’s support document here).
