Hey, this is a known macOS issue. It’s related to how Gatekeeper handles quarantine attributes on downloaded files.
Try one of these workarounds:
-
Copy the .app to your Desktop first, then move it to Applications. Don’t drag it straight from the DMG to Applications. This fixed it for most users with the same error.
-
If that doesn’t help, open Terminal and run:
xattr -cr /path/to/Cursor.appReplace the path with the right one, like
~/Desktop/Cursor.app. -
Or install it via Homebrew:
brew install --cask cursor

Let me know if none of these work.
