On my Macbook, I currently get:
- A request to log in to Facetime every time I restart it (I've never used Facetime, and don't intend to, and have lost access to my AppleId)
- A daily recurring notification to update my OS, which again I can't do without my AppleId
- A notification that comes every ~10mins reminding me that I'm low on disk space (like I don't know it)
