How to Find All Your 32-Bit Mac Apps at Once Before Apple Makes Them Obsolete
After downloading 32-bit apps from iPhone and iPad in iOS 11, Apple prepares to provide the same for your Mac. If you’re worried about losing access to some of your favorite applications, here’s how to check if all the software running on your computer is 64-bit or not.
The latest macOS High Sierra 10.13.4 will tell you which apps are still running 32-bit automatically. The next time you start, you will receive a warning that it is “not optimized” for macOS. After doing this, the app will still work, but future Mac updates may create problems .
If you don’t want to open each application individually, there is an easier and faster way to check them all at once (via iMore ). All you have to do is open Spotlight (type Command + Spacebar or just click the magnifying glass in the upper right corner of the screen) and search for “System Information.” Then open the program and scroll to Applications under the Software section on the left side of the window. It will take a few seconds for all your apps to load information, but then you can check the rightmost column to see which apps are 32-bit and which are 64-bit.
If you notice that the application you use all the time is 32-bit only, there are several things you can do. First, check to see if you missed a recent update that fixes the problem. If that doesn’t work, you can try contacting the developer directly and ask them to update the app to 64-bit before it’s too late. Finally, you can look for alternatives to be prepared for when Apple officially drops support for 32-bit Mac apps.
