Mac Mini M1 - Bluetooth Drops & Wake Thunderbolt Display

Hi All,


I have a 2020 M1 Mac Mini. It hooked up to my Apple Thunderbolt Display 27" via an Apple Thunderbolt to Mini Display Adaptor. (This worked great with my old MacBook Pro 2019) I am also using the Black Apple Magic Keyboard and the Black Magic Mouse 2


Since getting the M1 Mac Mini I have noticed a couple of hardware issues.


First, 2 flashing pixels at the top of my screen. It might have been coincidence, but they appeared as soon as I changed from MBP to Mac Mini - I don' have the MBP anymore so I can test the thory.


Second, I get a lot of Mouse and Keyboard dropouts. I have reset the bluetooth module and factory reset the keyboard and mouse but it still happens.


Third, often the screen does not wake up out of sleep. I thought it was because the keyboard and mouse had lost connection, but I can still control them via VLC, this should also wake the screen, so this is now how I reboot the Mac for the screen to work again.


Just thought I'd put these issues out there incase I'm not alone.


Thanks

I use a wired keyboard and a bt mouse and have the same issues. I've been able to get the screen back by unlugging the monitor cable from the mini and plugging it back in. Sometimes it works, sometimes it doesn't. What's weird is that if I unplug it and flip the cable over, it's worked every time. I took it into Apple and they think it's an OS bug and will get fixed eventually.
