M1/M2 Macs Have Bluetooth Issues with the Mouse, Cursor, and Magic Trackpad 2

I've experienced mouse cursor lag on M1 MacBook Air, but for me it only happens after the MacBook has runs out of battery, gone into hibernation mode, then got woken up. (Trackpad) cursor will lag until the next full reboot. Seems to be a different bug, since mine has nothing to do with Bluetooth.

I have definitely seen that behaviour on my M1 MacBook Air, though not recently.

At the time I tried to do a screen recording but it didn’t show up. I figure it’s some weird hardware acceleration thing with the cursor that gets borked after a bad wake up.

Why a cross post of FUD from reddit?

I read the post, use incessantly M1 and M2 machines, with various OSes even, and NEVER have the discussed issue in the post.

Perhaps I've got good luck, but it's way more likely that the posting person has something screwy installed as a kernel driver, if things are working wonkily on the person's machine.

Many people have been reporting BlueTooth issues on their Macs. I personally have the same problem. But just because you don't experience it doesn't mean the issue doesn't exist for many others.

Do you have anything custom installed visible with

kextstat | grep -v com.apple

the only times (within Apple engineering) that our team saw symptoms like that would turn out to be 3rd party software.

could be hardware, of course. thanks for clarifying.

Didn’t Apple rewrite the Bluetooth stack in Monterey? That’s where a slew of issues started popping up for people.

Connecting to a device with a code is still completely broken.

can't answer that, but am curious to see the output of "kextstat | grep -v com.apple"

Running that command returns nothing:

``` Executing: /usr/bin/kmutil showloaded No variant specified, falling back to release Index Refs Address Size Wired Name (Version) UUID <Linked Against> ```

can you please cut-and-paste exactly what you ran with the prompt visible on the left? that's curious

This is the command I ran: kextstat | grep -v com.apple

w/o variations (-v), I see a whole list of com.apple items.

yeah that seems normal. seems buggy, like you said! thanks for testing what we could test this way.

the output you show looks right since the drivers with com.apple in their name were filtered out, and nothing (except the top labeling of output) remains.

this article you probably saw (and, agreeing with you, it seems crazy like you're hitting a bug)

Thanks for the link. I'll check it out. In the past, I've tried some of the techniques mentioned in the article. Sometimes BT issues go away but come back after a few hours...

It'd be nice if we could use magic trackpad 3 using USB. I tried connecting the USB cable to it but it seems like it still randomly uses BT because the USB cable only improves the issues to some extent.

i have this issue with my logitech mx master 3s. horrible lag on bluetooth, completely resolved with the dongle. there's definitely something worth fixing here.

Did your logitech mx master install a kext?

kextstat | grep -v com.apple

shouldn't show any third party things installed. If it does, that's very very likely what's wrong. (Disclaimer: was in Apple engineering for several years)

There's definitely some interference between BlueTooth and Wi-Fi going on and it's not specific to the new Macs. I experienced similar issues with my 2015 MBP when using BT mice. Switching to Logitech's dongle would completely solve the problem.

Yeah I remember having this on my 2015 mbp too, it was infuriating and I ended up switching to a wired mouse and keyboard at the time.

Best decision ever! I remember at the same time, my Lenovo T490s didn't have any BT issues with my mouse.

I never install anything but a vanilla macOS, and don’t have any kexts.

Been like this for years.

I guess now we know why it’s not fixed if this is the Apple engineering mindset.

Nah, thats just an attempt by a few years retired Apple engineer from a different division to help a person out on Hacker News, with an often pertinent idea.

Sorry, I let my frustration get the better of me.

Thank you for trying to help.

Of course. It’s frustrating if it’s an unfixed bug for so many.

nope, no kexts

I've had exactly the opposite experience with my MX Master 3 AND MX Ergo. Dongle is horrible, bluetooth is perfect.

No idea why, just is. It's not even sometimes, it's instantly noticeable and never goes away.

I had issues with Logitech over the years and found two main causes.

1. Battery degradation meant the mouse would appear charged but have variable lag at unpredictable times.

2. Too many devices using Bluetooth/wifi located in the same desk space.

Switching bluetooth off on some unused devices, headphones, tablet, spare laptop (or switching them off completely) to reduce interference did help

> 2. Too many devices using Bluetooth/wifi located in the same desk space.

that might have a lot to do with it, but its 2023, like cmon. I should be able to use more than 3 devices without horrible lag.

My experience as well, really no issues, albeit I recall John Siracusa mentioning that the last couple of OS X releases have been rolling out a new driver model where they are no longer kernel modules or something, and some growing pains were to be expected

all my bluetooth devices works horrible with a huge lag on M1 16.

Form my experience with Logitech mouses, dongle has always been way better that bluetooth. I noticed my phone was the most responsible device of all the mess. If I put it far away from my devices, it's better.

I get this lag when I'm using an older macbook pro (mid-2012) near my M1.

Logitech mouse drivers have always been bad ever since the haxie days

Does a Bluetooth mouse even use Logitech drivers on MacOS? I’ve never installed them.

Doesn't have to do with Logitech drivers. Using BT, Logi mice and keyboards are laggy. But using the USB dongle, they're perfect, even better than magic mouse.
