Reset IntelliJ settings to default?

You can simply delete the whole configuration folder ${user.home}/.IntelliJIdea60/config while IntelliJ IDEA is not running. On next restart everything is restored from the default settings.

How do I reset IntelliJ for osx?

$ ls ~/.IntelliJ*
ls: /Users/apple/.IntelliJ*: No such file or directory

Well, the original post is nine years old, there have been minor changes since then... :)

The new location is ~/Library/Preferences/IntelliJIdeaXX

Be aware that the Library folder may be hidden in the finder.

Sometimes that 9 year old post is one of the top hits on google.
Thank you, your suggestion worked ... I simply shutdown IntelliJ, and then did the following:

$ rm -rf ~/Library/Caches/IntelliJIdea15
$ rm -rf ~/Library/Preferences/IntelliJIdea15

And that reset IntelliJ to where I wanted it ... i did have to re-enter my license activation code, but that was expected.
How do I mark your answer as the solution?

I think the routes are again different.

These commands worked for me.

rm -rf  ~/Library/Preferences/IdeaIC2017.2/

rm -rf  ~/Library/Caches/IdeaIC2017.2/

And now the paths are -

▶ rm -rf ~/Library/Preferences/IntelliJIdea2019.3

▶ rm -rf ~/Library/Caches/IntelliJIdea2019.3

I just wanted to reset Intellij's default settings then i found it :

Menu: File > Manage IDE Settings > Restore default settings...

And you just need to confirm then
No need to delete and re-install etc...

In IDEA 2023.2.3 go in hamburguer  menu  FILE > MANAGE IDE SETTINGS > RESTORE DEFAULT SETTINGS…
