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

I have the issue with disconnect, erratic behavior with Mousepad 2 and new 2020 Mac Mini which does not have the M1 chip; it has an intel chip. I think this is not related to the M1 but rather a bluetooth problem or a Big Sur problem.

OK, I've updated Apple Watch, iphone, and Mac mini to all of the latest available versions (beta or release). No problems so far, but do you want to see something funny? Look at the Bluetooth Explorer Link Quality Graph below (lower left corner). The red line is the link quality from my Magic Mouse 2. Notice how it starts at 100, and 3 times it drops and then returns to 100. The 100 level represents not using the mouse at all, the 3 drops are when I put my hand on the mouse like I'm going to use it, but NOT USING IT. Just my hand on the mouse reproducibly reduces the link quality. I didn't get any disconnect-connect-disconnect-connect issues, and I have no idea if it part of the connection issue, but it is pretty funny (and yes, I have been told I have a weird sense of humor). Same thing happens with the trackpad, not illustrated below.

Yes, it did autogenerate the reports, but they just emailed me asking for some logs from my iphone the next time it happened? That's confusing, in that it isn't an iphone issue that I am aware of, so I thought it was just a mistake.

I've updated the Apple Watch to the latest software, the iphone to the latest software, and the latest big sur update 20D64. I haven't used the M1 heavily, but no disconnect/connect/disconnect/connect issues so far, so I'm hoping that something changed for the better (the mouse does get a little laggy, though, but stays functional).

So, time will tell. I'll try to use the machine heavily today and see if it happens.

I've been using an ASUS USB-BT400 dingle happily with very little issues until I started backing up and updating to iOS/iPADOS 14.4 2 iPhones (6S and 11) and 2 iPads (Pro 2016 and Air 2018) when the Trackpad, Mouse and keyboard Bluetooth connection went absolutely crazy. Continuous reconnects/disconnects but even even the Bluetooth pref panel said the keyboard was connected it was unusable (no response from any key pressed). Resetting the bluetooth module (using a wired keyboard which I keep at hand) did not remedy it. In the end I restarted the mini m1 and reconnected all devices.

Another thing I noticed since the beginning of this week was that, after a shutdown/restart, the bluetooth devices would no longer reconnect when the dongle was in my monitor USB connector. I have now placed the dongle directly in the back of the mini m1.

I’ve had no Magic Mouse 2 disconnections since the iPad Pro and iPhone were updated to IOS v14.4. No changes at all made to the M1 MacBook Pro and have been using it constantly through each day since the updates.

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?

I have upgraded to OS X 11.2, my iPhones are all updated as are my MacBooks and iPads along with Apple watches. I removed my ASUS BT 4 dongle and have been using my Magic Keyboard and Magic Mouse 2. Last night while typing I encountered the delay phenomenon where nothing would appear for a few seconds and then suddenly a string of characters would appear. For now I resolved it by plugging in my keyboard to the USB port. I would say that they have not fixed the problem. Also, my Apple Watch will not unlock my M1. Those of you working on the next beta need to report these issues to Apple development. I haven't noticed any lag with the mouse except on initial movement. After that it seems to be ok, at least for now.

I'm considering this problem solved, for me, too.

It has been a week, and everything seems to be working as it should...keyboard, mouse, trackpad.

Glad they were able to solve it with software updates.

I'm running 11.3 Beta 1 now, and also, no trouble. I haven't upgraded to 14.5 Beta 1 on the iphone, as is this is a critical device for me and I don't usually like to run beta software on something I rely on for work on a daily basis. That being said, everything is still working, enough so that I am now considering purchasing a MacBook Pro later in the year when they announce the new ones (but I may splurge and purchase the current M1 MacBook Pro; they are very fast).

I believe the keyboard and mouse usually only connect to one machine at a time, and they were connected to your other Mac. The easiest way to fix this is exactly what you did. Now, they should work without the USB cable. The other way is, when they're already connected to one machine, use the Bluetooth menu bar icon to reset the keyboard and mouse. That should free them to connect to your new Mac the usual way. Glad you found an answer.

Received M1 today. Cannot connect to my Magic Keyboard at all. Connects immediately to Logitech K380 ... and the Bluetooth connection dropped upwards of 40 times during a job that I had to time... one hour and five minutes. Sometimes it stayed connected for up to 10 minutes; sometimes for too short a time to type a complete word. The mouse is better but also iffy. A pair of AfterShokz phones also disconnected repeatedly.

It's like buying a Ferrari with three wheels.

11.2.1 does not help my magic mouse lag/drop/stutter. it seems to come and go based on how much CPU or GPU the M1 is using, and when video editing, it's a lot. I've moved all things away from the mouse etc etc, to no avail. Hopefully 11.3 fixes...?

My issues only pertain to mice (any brand, any wireless connection type) but it has never been cured with software updates or moving the computer around to different locations. I will say the frequency seems to have lowered in recent weeks but today all of a sudden, many dropouts on the mouse again in the same familiar pattern (drops out quickly twice in a row before stabilizing for a couple hours).

i agree. Ive got all kinds of generations of apple devices lying around, and the farther I keep them away from my m1 mini, the better. But microwaves and other interference is so so common on my airpods airpods pros aircups pros whatevers, that I've just come to terms with it. It is what it is...

Just try a wired mouse. It can solve your problem
