On June 28, 2017, Apple announced that
macOS High Sierra will be the last macOS release to support 32-bit apps without compromise.
How can I find out which apps on my Mac are 32-bit so that I can see if I need to upgrade them?

Best Answer
One way to identify what 32-bit apps you're still using is to use the System Information option under About This Mac. The exact steps differ depending on the version of macOS you're running, but below are the broad steps you should be able to follow to suit your circumstances:
64-Bit (Intel)
Click on this column heading to sort apps by whether or not they're 64-Bit (i.e. they'll have either a Yes or No listed against each app).Refer to the image below as an example:
NOTE: In the above image I've deliberately not sorted the last column so you can see entries with both a Yes and No listed against them. So, in the example above you'll see that iMovie v10.1.6 is a 64-Bit app while iMovie 9.0.9 is not 64-Bit.
Edit - If the above steps result in an error
I have seen reports that a small number of users are getting a "The plug-in did not respond quickly enough while gathering this information" error message while waiting for the list to populate.
If this happens, quit the System Information app (or System Profiler app in older versions of macOS) and start again, but this time skip steps 1 to 4 and go directly to your Applications/Utilities folder and open the System Information app (or System Profiler app) directly from there. Once it opens, follow Steps 5 to 8 above.
