Introduction
In June 2018, Apple announced that macOS Mojave (10.14) will likely be the last release to support 32-bit software applications. In anticipation of this move by Apple, in August 2016 Microsoft created a 64-bit version of its Office apps for Mac, but depending on where the client downloaded Office for Mac from, it’s possible that they installed the 32-bit version. Clients may continue running their 32-bit applications as long as they do not upgrade their OS to anything newer than Mojave.
The following on-screen 32-bit alert, which run only once for each eligible application, will pop up when a client attempts to open a 32-bit application on a Mac that no longer supports 32-bit software.
To check which applications on a Mac are still running 32-bit versions, see the following procedure.
Procedure
- Click on the Apple Logo on the top left side of the screen
- Click on “About This Mac” from the Apple menu
- Click on the button marked “System Report” on the bottom left of that window
- Scroll down to the “Software” section in the left-hand pane
- Click on “Applications”
-
Locate the column headed “64-Bit (Intel)” in right-hand pane on the top right. You may need to widen the System Reports window and/or drag some column dividers toward the left to make the 64-Bit (Intel) column visible.
-
Click on the 64-Bit (Intel) heading to put the list of applications into ascending order. The 32-bit applications (if there are any) will be at the top of the list. Each will be marked “No” in the 64-Bit (Intel) column.
