Cursor not working anymore after Update

[tobiashaas]

Hey everyone,

I recently updated Cursor on my MacBook — unfortunately, I don’t remember which version I was upgrading from — and replaced the old app with the new one. Since then, macOS keeps showing an error message saying that Cursor.dmg is damaged.

I’ve tried downloading versions 2.2 and 2.3, but I’m getting the same issue with both.

Does anyone have an idea how to fix this?

Hey, thanks for the report.

This is a known issue with Gatekeeper on macOS. Please try these steps in order:

1. Remove the quarantine attributes:

sudo xattr -rd com.apple.quarantine /Applications/Cursor.app
sudo xattr -cr /Applications/Cursor.app

2. If that didn’t help, add it to the exceptions list:

sudo spctl --add /Applications/Cursor.app

3. Check ~/.cursor (make a backup first):
   Sometimes the issue is that ~/.cursor is a file instead of a directory:

rm -f ~/.cursor

4. Full reinstall (make a backup first):

• Remove Cursor from Applications
• Remove ~/Library/Application Support/Cursor
• Download it again from Download · Cursor
• Restart your Mac before installing

Let me know if any of this works.
