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.
Code:
defaults write -g CSUIDisable32BitWarning -boolean TRUE
 
Try using this command:
Code:
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?
 
So I tried this last month from terminal (not sure how to enforce it at a system level) and 30 days later I am getting the "not optimized" message again.
Code:
defaults write com.apple.coreservices.uiagent CSUIDisable32BitWarning -bool TRUE

On my system (macPro3,1- Mojave) I've only ever seen this message the first time I run an older 32bit app, after acknowledging it I've never had it return again for that same app.
