Does this stop you from using Cursor

Yes - Cursor is unusable

6

This is a known issue: on macOS, the in-app updater can leave the app bundle’s code signature in a broken state after an update, and macOS then refuses to launch the app. That matches your crash log exactly (Library not loaded: @rpath/Electron Framework.framework... different Team IDs). It’s the broken signature from the partial update, not the version itself.

The fix is a clean reinstall:

  1. Fully quit Cursor Nightly.
  2. Delete /Applications/Cursor Nightly.app. This only removes the app itself. Your settings and chat history live in ~/Library/Application Support/Cursor Nightly/ and are left untouched.
  3. Download a fresh copy of Cursor Nightly from the Cursor downloads page and reinstall.

If you want to confirm the broken state first, run codesign -v "/Applications/Cursor Nightly.app" - it’ll report the signature as invalid before the reinstall and pass after.

Our team is aware of this and is tracking it. The reinstall restores a valid signature and gets you back up and running.
