Waiting for extension host (MacOS)

Hey, this is a known issue. The team is aware and tracking it. I’ll need a bit more data to understand the exact cause in your case.

Try these steps in order:

  1. Run Cursor from Terminal with cursor --disable-extensions. If it works, the issue is caused by an extension.

  2. If that didn’t help, try cursor --profile-temp. This will rule out your profile settings and state.

  3. Check what’s inside the cursor-socket directory:

ls -la "/Applications/Cursor.app/Contents/Resources/app/extensions/cursor-socket/"

If there’s no out/ folder, that’s the cause. Reinstalling Cursor should fix it.

  1. If none of the above helps, open Developer Tools via Help > Toggle Developer Tools, go to the Console tab, wait for the error, then paste here all red entries.
