4th Gen 2020 M1 Mac mini bluetooth issues with Magic Mouse2

I agree; I've gone 24 hours now since the last upgrade (and upgraded both iphone and Apple Watch), and no issues so far. First time I've been able to use the computer for a full day since I received it!

I also received the Asus BT500 dongle today, but will hold off on trying it since things are working so far (and don't want to mess it up).

Keeping my fingers crossed, but so far so good!

Has anyone else noticed bluetooth devices being removed from user accounts when a second user signs in? My wife and I both have our own user accounts and iCloud accounts. When she signs in to her user account on the Mac her AirPods go on to my account and delete my Beats Solo Pro headphones from my iCloud account. I am going mad trying to figure it out.

I have the same bluetooth issue. I have the new Apple Trackpad and this drops connection at the same time as my Logitech mouse and keyboard.

Only started in last 24 hours (30 Jan 2021 and no issues since I bought in December 2020.

Will Apple accept return and refund under warranty?

No. I bought two Mac mini M ones in December and brought one to the Genius Bar. They kept it for 24 hours and called me to say that the hardware appeared to be fine. So they would not refund me. I sold the two minis at a substantial loss and purchased two PowerBook pros.

Apple engineering just emailed me this morning to ask for additional feedback regarding the BT connection issue. I am guessing that even after 11.2 RC3, the engineers either are still receiving BT bug feedback, or want to be confident that 11.2 RC3 and iOS 14.4 have fixed the issues. I did report some Apple Community members encountering mouse & keyboard lag even after updating to 11.2 RC3, iOS 14.4, and WatchOS.

Thanks for doing this.

Even though I’m experiencing this less frequently, it’s still troubling when it occurs. It can be hard to get the BT connections established quickly and it interferes with work.

Well, two days without any mouse disconnect/connect/disconnect/connect, and keyboard seems to be working reliably as well.

Maybe this last upgrade helped, along with upgrading to the latest Apple Watch and iOS software.

I'm getting optimistic that they may have fixed this. How is everyone else doing? Have you upgraded to the latest beta, as well as watch and iphone software if applicable?

What version of macOS are you using? I am on 11.1 and just experienced a complete bluetooth connection shutdown (all my bluetooth devices connected to Mac mini lost connections). Have to restart to get it fixed.

I have a similar issue with my 3 week old M1 Mini. My bluetooth will sometimes stop working when the mini goes to sleep. The only resolution was too reboot. This morning it couldn't get it to wake so I tried the reboot. Still no luck. I had a spare wireless mouse that I could get to work however when it came time to type my password into the login screen my Apple bluetooth keyboard (it's a seven year old model) would not respond so I was stuck. I tried rebooting, resetting SMC, unplugging all the peripherals, all of the known troubleshooting procedures and still no luck. I then called Apple support and they too could not help to troubleshoot because I needed a keyboard to get beyond the login screen.

I went to plan B and went to my local Target and bought a $10 Logitech USB keyboard. I plugged it in and was finally able to enter my password. I then was able to re-establish my bluetooth connections to my mouse and keyboard. I will be keeping the $10 keyboard just in case this happens again. Bluetooth issues with Big Sur appears to be an issue according the the research I did. APPLE, THIS UNACCEPTABLE! FIX IT!

I have been using the Asus BT-400 adapter for weeks with very good results. Everything worked except for the watch unlock, which I don't care about. I have now installed the 14.2 release that just became available and will monitor for any issues. Hopefully I do not have to go back to the external adapter. Will monitor for a few days and report back.

Several glitches on the install, My LG 4K monitor went berserk during the installation, but I just let it cook for awhile and eventually came back to show the install status. Also after removing my BT-400 and restarting, none of my Apple BT devices connected until I plugged them into the mac mini. Once that was done they connected just fine. Probably an artifact from running not he external adapter. No big deal as several restarts confirmed they would connect each time after that.

I just installed macOS 11.2.

First thing I noticed is I was able to enter my password over Bluetooth, without having to plug in a USB cable to the Magic Keyboard 2. THIS ONE ISSUE IS FIXED — I was never able to do this before.

Everything else is working well, including my BT Magic Trackpad 2 to BT speaker. But it has only been 2 hours, so as you all know from experience, I'll need to keep on watching this and report back after some time has passed.

Note: The Bluetooth Explorer app seems to have been further degraded, as the only part that seems to (possibly) work is the log window. The graphs, etc. are not functional. And even the (only) entry in the log is reported in UTC, not local time.

So far so good, having installed Big Sur 11.2 this evening, with no Bluetooth disconnects yet - and already having installed iOS 14.4. Don't want to tempt fate though, but overall reports seem positive so far... 🤞🏻

I just installed BS 11.2 on M1 Mini. The disconnecting of bluetooth mouse and keyboard (which was really erratic yesterday) seems to have stopped after the install. However, both key board and mouse are laggy ... in reality not enough of an improvement for me to stop using the USB mouse. Unfortunately.

Installed BS 11.2 today (installed iOS/iPadOS 14.4 on all devices yesterday) and sad to say it doesn't make any difference. Still experience a lagging Apple Magic Mouse (to the extent it makes editing a picture, for example, when I need precise positioning, virtually impossible).

What I also noticed is that Bluetooth Explorer only reports link quality for my Apple Keyboard and not for my trackpad and mouse. Very strange.

Just updated mine to 11.2, and have turned the "wake on" back on. Let's see how that goes and if it works well, I may put the BT keyboard back on as well. Fingers crossed we are good to go, as you say outside of this issue, the Mac Mini M1 is awesome!
