32-bit application alert message in macOS 10.13.4

April 12, 2018 Leave a comment Go to comments

Starting on April 12, 2018, Macs running macOS 10.13.4 will display a one-time alert when 32-bit applications are opened. This alert will appear once per user account on the Mac, when a relevant 32-bit application is opened.

When the Learn More… button in the alert window is clicked, the following Apple KBase article opens in your default web browser:

32-bit app compatibility with macOS High Sierra 10.13.4

For those who need to stop this alert from being displayed in their environments, I’ve built a management profile to suppress the warning. It is available on GitHub via the link below:

    Thanks for making this. What is the Preference domain do you recommend if I am making a custom config profile in JAMF? I see both .GlobalPreferences and com.apple.ManagedClient.preferences listed in the plist.

    This seems to not work anymore on 10.14.4 (and assuming onwards). Was working fine on everything up to 10.14.3.
