    I recently upgraded my system to Mojave and still have a lot of 32bit apps which presently I have no intention of replacing (MS Office).

    Has anyone found a way of totally disabling the "This app is not optimized" message for 32 bit apps. The pop-ups keep occurring about every 30 days.

    I found this setting but appears to work in High Sierra, but not in Mojave.
    defaults write -g CSUIDisable32BitWarning -boolean TRUE

    Yeah, it's annoying. I don't think there's an "off" button.

    Try using this command:
    defaults write com.apple.coreservices.uiagent CSUIDisable32BitWarning -bool TRUE
    See here: https://support.apple.com/HT209028. It might be required to enforce this at a system level and/or via a configuration profile.

    This looks promising. I haven't had a chance to try it just from terminal (and then I guess I have to wait 30 days and see if I get another pop-up...).

    I have no experience with "custom configuration profiles payloads" that the link speaks about. Haven't done any googling on it yet, but do you know about this, or can explain it in a nutshell?
