I’m unable to launch the application—I’m on macOS 26.5.2 and Cursor version 3.9. Can anyone help me?

Hey, let’s try this. Most of the time on macOS 26.x the app won’t launch because the code signature got corrupted after an auto-update, and a clean reinstall fixes it:

  1. Fully quit Cursor.
  2. Drag /Applications/Cursor.app to the Trash.
  3. Download the latest version from Cursor · Download and install it again, or run brew install --cask cursor --force.

If macOS says the app is damaged and can’t be opened, after installing run this in Terminal:

xattr -dr com.apple.quarantine /Applications/Cursor.app

To narrow down the cause, please share the exact error text you see on launch, or the macOS crash report from Console.app > Crash Reports, or the Report dialog when it crashes. Let me know if the reinstall helped.
