Hey, this is a known macOS Gatekeeper issue. 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
  1. If that didn’t help, add it to exceptions:
sudo spctl --add /Applications/Cursor.app
  1. Check ~/.cursor (make a backup first):
    Sometimes the issue is that ~/.cursor is a file, not a folder:
rm -f ~/.cursor
  1. Full reinstall (if nothing helped):
  • Delete Cursor from Applications
  • Delete ~/Library/Application Support/Cursor
  • Download again from https://cursor.com/downloads
  • Restart your Mac before installing

Usually the first command fixes it. Let me know if it still doesn’t work.
