It seems that I am the least fortunate with my Mini M1. I am using Mac mini M1 for a week now and waiting also for air M1. But now thinking about cancelling air and returning mini.
1. Bluetooth drops almost all the time, mice, speakers, everything except Magic keyboard
2. Getting a lot of app issue, even Apple ones, Safari sometimes takes 80% of cpu with one-two tabs, Spotify stops playing music for no reason. Once everything hang that I couldn't even do a force quit (which I never experienced on my old MBP). It seems that in many apps, there is some kind of 1 second lag when doing sth.
3. After every restart getting "Your Mac restarted because of a problem"
4. Very often I have problem waking mini from sleep.
5. After several days I started getting some weird purple tint issue in both light and dark theme (I found that there was a similar issue several years back and it was some software bug).
Generally it seems very unpredictable, one day is fine, another day it seems that it's barely useable for any normal work. Not really sure if I should wait a week or two for some update, or just return it and buy it maybe in half a year.
