Mouse Lag When Connected To Bluetooth Headphones - 2022 MacBook Pro 13.3” M2

No one. Why do you ask about USB devices?

Problem 100% in Bluetooth chipset.

I've already written about it: I tested it on old PC which costs $100 with 5 Bluetooth devices includes Apple magic mouse and Apple touchpad + mx5 + TV + apple pods + printer, everything works properly. But my $2000 Apple MacBook Pro can't, it's ridiculous, isn't it? It starts lagging after some random time, approx 10-50 min. And Only reboot Bluetooth helps

It's not a software bug, try to google, there are 1000 articles with this problem. I am pretty sure that it's a hardware problem, and won't be fixed

My Mac Pro M2 Pro is supper laggy when I have tried to connect 2 or more Bluetooth devices (Beat Studio buds cannot hear properly when using a mouse, the mouse would lag if using Beats Studio buds...). After an hour of chatting, and contacting Apple support then I realized that it was a "function" of the Macbook Pro. Your only choice is to use USB connections or JUST USE ONE BLUETOOTH DEVICE AT A TIME.

Bluetooth uses the same spectrum as 2.4 GHz Wi-Fi.

it is also subject to USB-3 generated interference:

Why do I have difficulty with Wi-Fi or Bluetooth devices when USB 3 devices are attached to my computer?

Some USB 3 devices can generate radio frequency interference that can cause Wi-Fi and Bluetooth devices operating in the 2.4GHz band to have issues communicating with your computer. Here are some tips to avoid this issue:

• If your USB device has a cable long enough that you can move the device, place it away from your Mac—and make sure not to place it behind your Mac, or near the hinge of its display. The antennas for Wi-Fi and Bluetooth are located there, and USB 3 devices placed there might interfere with your wireless connections.

• If you're using adapters or dongles on a Mac computer with Thunderbolt 3 (USB-C) ports, plug them into the front port on the left side of your Mac, or into the ports on the right side (if your computer has them). These ports are the farthest away from the antennas, making interference less likely.

• To avoid interference on the 2.4GHz band using Wi-Fi, try using the 5GHz band instead. You can change this on your wireless base station. Bluetooth always uses 2.4GHz, so this alternative isn't available for Bluetooth.

I have same issue with M1 MacBook Pro. How can I fix that ? I couldn't find any solution.

Hey there parmar_parth91,

Thanks so much for using Apple Support Communities.

For this particular issue, we want to recommend a couple of basic troubleshooting steps that have a solid track record of resolving this type of issue. We would recommend trying these steps and testing the issue after each one:

• Shut down or restart your Mac - Apple Support
• Update macOS on Mac - Apple Support

If the issue continues to occur after rebooting and updating, another good step to test is booting your Mac into Safe Mode. Once you boot into Safe Mode, you can test the issue out and see how your Mac performs. If the issue stops occurring in Safe Mode, you can then reboot your Mac and test the issue again to see if it may be resolved. This article has some more information: Start up your Mac in safe mode - Apple Support

We hope that this information is helpful.

​Have a great day!

There is no pervasive group of reports that suggest a design or performance issue in these Macs.

If you think the problem is in your Mac, contact support and get them to have a specialist work with you to solve this, or file a bug report on your behalf:

I am having similar issues with connecting headphones and bluetooth lag. The only solution I have found is to turn off one of the bluetooth devices and turn it back on. It will resolve itself. This is getting very frustrating that I have to do this every time I have to connect my headphones.

Headphones Used:

• Airpods Pro 2
• Airpods Max

Keyboard/Mouse:

• Magic Keyboard
• Magic Trackpad
• Magic Mouse

Magic Mouse does the same thing as the Magic Keyboard, Magic Trackpad.

On any day, I only have one pair of headphones, Keyboard, and Mouse or Trackpad turned own.

So only 3 items connecting to Bluetooth. I have a USB-C to HDMI, a USB-C webcam, and USB-C Lightning cable, plus power.

The 2.4 GHz spectrum used for Wi-Fi is also used (somewhat differently) by Bluetooth. Bluetooth usually dodges congestion there by using frequency hopping, rapidly cycling through the channels.

Microwave ovens, baby monitions, and landline cordless phone systems contribute more noise.' Internet of Things' devices, wireless speakers, wireless headphones, and other stuff adds even more.

The radio frequency interference generated by badly shielded USB-3 devices also contributes to the noise in that part of the spectrum.

Problems like yours are NOT likely to be caused by defects in the chips used. They will vary widely by how much other "stuff" is in your 2.4 GHz band of your specific 'network neighborhood'.

If you can't get the mouse to work while the wireless headphones are working, consider switching to wired headphones to reduce the number of competing devices.

<<. I realized that it was a "function" of the Macbook Pro. >>

As I have indicated above, I disagree.

[in my opinion] It is a function of congestion and interference is YOUR "Network neighborhood". You are sharing this same small slice of the radio airwaves with all your neighbors 2.4 GHz band Routers, internet of things devices, Microwave ovens, baby monitors, badly-shielded USB devices and cables, and possibly badly-shielded stand-lone displays as well. If your network neighborhood is full of signals, Bluetooth devices can't work the way you want them to.

I also have my desktop right next to me, which has an Intel AX200 wifi+bluetooth card. And you know, the Bluetooth on my desktop works just fine with more connected devices (my MX Master 3S, keyboard, Beats Studio, Xbox controller, and also Dualshock 4).

How does the Apple Magic Mouse act under these circumstances? My guess is this is a compatibility issue with the logi Mx Master 3.

No, same issue with sony-mx5 and apple magic mouse. It's hilarious, because my old notebook which costs $100 works proper

No, it's problem only with MacBook on M processors, my old one works properly

do you have ANY USB peripherals connected?

if yes, which ones, exactly?
