What's Wrong?

There was previously a bug where Claude desktop for Mac would not close properly - one was forced to quit using the tray icon. This bug was fixed. But one bug remains, and that is when shutting down the Mac, then Claude desktop does not quit and causes the Mac shutdown to stop/abort.

What Should Happen?

When shutting down the Mac then Claude desktop should quit automatically.
