<< Solved >> Problem Deleting Apps on Mojave 10.14.6 Downgraded from Big Sur

[wstrohm]

After downgrading from Big Sur to Mojave successfully, there are apps in Applications folder which I am not allowed to delete since they are "required by MacOS," even though they display an error message if I try to open them. Examples are "News.app" and "Voice Memos.app." Also their preference.plists cannot be deleted for the same displayed reason.

Is there a way to get rid of these non-functional "required by MacOS" apps apparently carried over from Big Sur?

Did you try disabling SIP and then delete them ? Just a guess.

I'll try that; thanks for your suggestion.
[Edit: That worked; thanks much!]
