macOS 32bit Application Warnings

Apr - 14 2018 | By

Starting on April 12, 2018 macOS 10.13.4 will start alerting you when you open a 32-bit application.  The purpose of this alert is to have people contact the company or programmer who wrote the App to have them update their program.  macOS 10.13 High Sierra is the last version of macOS that will run 32-bit applications without compromise.

App is not optimized for your Mac. This app needs to be updated by its developer to improve compatibility.

The goal is to have all applications be 64-bit for the next version of the macOS to be released.

Apple’s article on this alert –

How do I find the 32-bit apps on my Mac?

If you are wondering what 32-bit applications you have on your Mac you can use the Mac Check 32bit application I have written.  It will provide you with a web based report of all 32-bit software that is detected on your Mac.
