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

I just ran into this problem after days of no problem on new M1.

I read it could be the iPhone nearby. So, I turned off BT on the XR and, bingo, the Magic Mouse works fine.

Until… it suddenly disconnected. But a quick click brought it back.

Apple, you need to fix this BT problem on Big Sur ASAP.

I have same problem, magic mouse 2 just can't connect to the new iMac mini M1 . The Imac finds the mouse but when you push connect it won't, saying “The pairing attempt was unsuccessful, click continue to try again” I tried again a hundred time with no success.

Now I use an old Logitech mouse with USB dongle.....common apple fix it.

Today the same Problem resurfaced. First I switched off my keyboard, because it had low batteries (23%). That did not change the lagging of my MX Anywhere 2S. Then I switched off the old (1. Generation) Trackpad. Immediately the lagging stoped.

Hope someone can make sense of it.

Ok seriously guys I think I figured it out!

I was trying to solve this jaggy/jerky mouse (Logitec M590 wireless using bluetooth) for ages on my 2021 Macbook Air M1 (base model).

What I did was I disabled the Giant "Shake to Find" Cursor in MacOS because it was bothering me, and INSTANTLY I get SMOOTH MOUSE!

Just also of note, I did notice a difference also turning off my Apple Trackpad that usually would sit nearby the mouse. I also did try the sound output to not the macbook air M1 speakers (I sent it to Homepod Mini nearby). I did also (just to note) install the logitec drivers, but didnt start noticing any difference till I got rid of shake to find and turn off external trackpad power.

I think it is a combination of issues, that's why Apple is having issues fixing this, and this is totally bs that Apple didn't catch this issue during basic testing of the laptops before launching to public, Steve would be super super not cool with what's happening, a mouse is the MAIN input into these. A laggy mouse makes me feel like I'm using a windows laptop from 1996. I suspect this is a hardware issue (bluetooth motherboard unit shielding/bandwidth/interference issue) AND a software issue.

Since (I believe) Big Sur 11.2.2 my bluetooth connection quality improved to the extent that I stopped using my Asus dongle. Unfortunately since about a week the connection quality of my Apple Magic Mouse (1st ed) dropped again to a level that I deided to revert back to the Asus dongle.

I did notice that my problems returned at the same time Apple pushed a new version (2143) of Xprotect on April 1st (no joke). Unlikely the two events are linked but I thought it wise still to mention.

So here we are many months and countless posts later and the Magic Mouse 2 / M1 Mini Bluetooth issue still exists. I just received my new M1 Mac Mini and guess what? Mouse lag (skips, stops, scroll jumps, missed clicks, etc.). I took the time to read this entire thread and tried every reasonable fix (plist delete, BT phone off, reset BT/devices, etc.), but none resolved the issue. The most functional setup appears to be disconnecting any non-powered USB hubs. Although turning off BT on nearby devices did reduce lag severity and recurrence somewhat, removing non-powered USB hubs solved the problem even with nearby BT devices on. I do not know how USB power draw affects BT (perhaps some of the more experienced techs can comment on this), but it does on the M1 Mini. I tested this with several USB C and A hubs and the results were the same: non-powered hubs caused BT lag issues. Unfortunately, I do not have a powered USB C hub to test, but with a powered USB A hub connected there is no lag. I was unable to find info for USB C hubs with power pass through regarding whether they can be safely plugged into the TB port on AC direct/non-charging machines (iMacs, Minis, etc.) and whether they use the power input to power the hub. Subsequently, I did not test a USB C hub with power pass through in case it caused problems with the TB port. Perhaps there are much fewer M1 MacBook issues reported because of power pass through on USB C hubs, whereas more Mini users have non-powered hubs.

No, but my hub is inside the LG 27" screen. It was a little problematic when I first got the M1 mac mini but since they issued the updates I've been fine for 99% of the time. Very rarely I get a lag and the "fix" is to plug in the trackpad or keyboard (both apple) into lightning and that fixes it. Much less annoying than when it happened ALL the time..

I've almost forgotten about it now - but your post made me think of it again..

I purchased a Mac Mini with the intel processor last year and I'm having the same issue with bluetooth devices disconnecting for around 30 sec or more. I have spoken to apple about this issue and have taken it for service. I was told they don't have any issues with the bluetooth devices on the Mac mini, if that's the case why are their so many complaints online. After factory resetting my system twice, once from me and also at the apple store the problem still exist, so they ordered a new logic board and guest what? I have tried 3 different keyboards and 4 different headsets all brand names like Logitech, Beats and Sennheiser.

It's still happening and getting worse. I have to call apple back again on Monday. Is the the bluetooth chip or the BigSur OS, something is very wrong. I paid too much money and It's used for business. The worst thing for me is when i disconnect during zoom or other meetings when I'm presenting.

I have to share that I purchased the OWC new Thunderbolt 4 Dock and all my M1 MacMini issues with Bluetooth and with displays not waking up have disappeared. I routed everything but HDMI to my second screen through the Dock, Bluetooth directly through the MacMini and all is behaving itself. I made sure I had USB-C/Thunderbolt cables to my LG 4K screen, the Dock, and my Thunderbolt drives. I regret I had to purchase a third party dock to get a new Apple computer to behave properly but am finally enjoying a machine that provides high performance and performs predictably.

David-

Specifically, which OWC Hub did you buy? They have a new Thunderbolt Dock (which is new) for $249, an older one available in 2 finishes (Thunderbolt 3 dock), and a Thunderbolt hub (which is new) for $149.

Thanks!

Just now installed Big Sur 11.3. It took only ten minutes to find out it did not solve my Bluetooth issues (lagging Apple Magic Mouse Gen 1). This is the more frustrating as I had less problems using 11.2.2 and (for some time) 11.2.3.

Reverting back to my Asus BT400 bluetooth dongle solution which still performs without hiccups.

Just thought I would chime in here... I am having the same experience as Zhaobello and I am running 11.1 but have been having the BT issues since 11.0.

I haven't tried the beta yet.

Yep. I still hope it's software related.

For me, the other two issues I've encountered is:

1. External monitor via USB C to HDMI doesn't wake up about 25% of the time
2. I've had a few random shut downs :o

Sorry, it won't let me post the picture. I'll have to try again.
