M1 Mac Mini bluetooth issues fix?

I have a Mac Mini M1 16GB/256GB. Just purchased a Hagibis Hub which arrived today.

Some observations:

• To begin I had Wifi switched off - working with Ethernet.
• As soon as I began using the hub I started to experience Bluetooth issues with my magic mouse.
• Turned system off and swapped USB-C to USB-C cable that came with the hub from left port to right port on Mac.
• No more bluetooth issues.
• Until I then switch Wifi on again...bluetooth issues returned.
• Turn wifi off again...bluetooth issues gone again.

Mainly for mechanical drives which are no longer offered on Macs. Replaced by high speed, low power, internal SSDs, which makes sleep unnecessary because power savings are negligible (while issues like yours abound). If you’re not convinced, shut/start, the later Macs do both extremely fast.

It used to have benefit which is why it was default ON across all their platforms, but today it’s mainly only trouble. Just like it’s too much trouble for Apple to change the defaults and explain why...

...turn it off and fuhgetit, nothing to lose.

What’s the problem with USB?

I just started having similar problems on a 2014 Mac mini running Big Sur, the keyboard, mouse and trackpad suddenly started disconnecting and reconnecting every minute or so. I assumed a hardware issue but started to look back to what else had changed the day before it started, and led me to the Apple TV I'd put in the same room the night before. Turning off the Apple TV cured all my problems. Don't know why but obviously my peripherals were being hijacked or trying to connect to the Apple TV.

I have the same issue with two M1 MBA's in a row... updated to 11.2.3 - problem persists.

I'm using Logitech Mx Keys and Logitech Mx Master 3. This really *****.

Mouse stutters terribly. Keyboard also laggy. This is terrible!!!

Im definitely returning my MBAs if they don't offer a timely solution. Im really disappointed.

2 HDMI monitors, 2 4TB external hard drives, wired keyboard, wireless mouse with USB dongle, mini and micro SD reader. As long as Apple continues to play the minimalist game, there will be a need for hubs. If these hubs kill the only ports that Apple is providing, then they need to figure out a better solution. Early adoption shouldn't mean killing off a tech before it's actually dead.

had the same problem. spoke to Apple tech any times. Was using older magic mouse and keyboard that were Bluetooth 2.0 based. Switched to newer magic mouse and keyboard that are 3.0 based. Will know in a few days if this fixes problem.

That is a rather strange assertion to make. Explain how I can hook up my webcam, electric piano, audio interface, keyboard, mouse, stream deck, and sometimes a flash drive or other device with just 2 USB ports? The only 2 from that list of 7-9 devices that could be made wireless are the keyboard and mouse.

Sure, for a large portion of users, they can get by with just the 2 USB-A ports and 2 USB-C ports. But any content creator of any type simply can't get away with that.

4 USB ports, the C are readily converted to A with suitable cable/adapter. The Intel version has 6 (in case you haven’t bought yet). If you throw in a monitor with built-in hub, in most cases a mini-connected USB hub isn’t necessary, especially since the keyboard, mouse, flash drive and “other device” don’t need one dedicated.

But if that doesn’t work for you, by all means, use a hub, but be aware they’re not all the same. Many can cause issues with interference and some powered hubs have been known to take ports out completely. Just so you’re aware.

Yeah I mentioned 4 total, 2 type A, 2 type C. But that is only 3 usable if you are using one of the type C ports to connect your monitor. The intel version with 6 ports plus the assumption of a couple monitor ports could get me by, but I have the M1 version of course. Most monitors only extend USB ports by 2, sometimes 3 or 4. So either way I am still forced to use a hub with the M1 Mini. I do use a bus powered hub though, not external power.

I am not sure why they reduced the ports by 2 for the M1 version. Those extra 2 ports would lead to a lot more flexibility. If it had the 2 extra and I had a monitor with 4 USB ports on it, I would not need the hub.

Yes, sadly I already experience some interference at times. It only happens once in a while and I have not been able to narrow it down just yet. It's mostly noticeable with mouse tracking when it does happen. I am hesitant to blame it on the Mac Mini or things connected to it just yet as I have other devices in the vicinity that could be contributing. It's a little annoying when it does happen but it isn't too often thankfully.

I am still having this problem but I have a workaround!

With my setup (Mac mini M1, Bluetooth keyboard/mouse, old iMac in Target Display Mode as monitor) bluetooth freezes up about once a week: keyboard starts "stuttering", mouse behaves erratically, etc.

My workaround _used_ to be to switch to the iMac, screen share to the Mac mini, turn bluetooth off and on again.

But that's a hassle, so I have now installed `blueutil` through Brew, and whenever I have bluetooth issues I run the following script:

```

#!/bin/bash

blueutil --power 0

echo "bluetooth power off"

sleep 10

blueutil --power 1

echo "bluetooth power on"

```
