If you tried to delete an IntelliJ IDEA from your mac station you know that problem is not simple, so, I’ve decided to write short note “how to clean your mac after deleting IntelliJ IDEA app from Application folder”.
Generally check all next folders and clean/change what you want:
~/Library/Saved Application State/com.jetbrains.intellij.savedState
Where it can be used ?
If you have some problems in update;
If you have problems with license;
If you have problems with old (incorrect) prefereces;
You just want clean installation of new version of IntelliJ IDEA.
