Apple - How to delete a locked app, Karabiner?
It should be done in the app itself.
In “Misc” tab, press the "Uninstall Karabiner-Elements" button.
You can also uninstall Karabiner-Elements from command line.
$ sudo '/Library/Application Support/org.pqrs/Karabiner-Elements/uninstall_core.sh'
Documentation
For any other app/file which are locked, try to unlock it by unchecking the "locked" box in "Get Info" first.
If the box is greyed out, run the following in Terminal:
cd "/Applications"
sudo chflags noschg "Karabiner-Elements.app"
Then delete it by right click > "Move to Trash"
Read more about noschg at man chflags.
I had forgotten I had installed this app, but accidentally deleted the kernel extension and uninstaller script. I was left with an app that could not be trashed or removed or moved in any way.
Solved it like this:
- Download Karabiner-Elements
- Install
- Launch the app
- Go to "misc" and uninstall with the uninstall button.
- reboot
And then never install it again.
Really very annoying, I spent a lot of time trying out different suggestions but none of them worked. Changing the flags, changing the user, etc.
