MacBook Pro bluetooth issues when paired with Bose QC35 and Logitech MX Master Mouse

I updated to High Sierra and the problem has mostly disappeared for me. The connection to my headphones still has some occasional stutters, but nothing near as bad as pre-High Sierra.

Sorry to say... this has been an issue with Mac OS X and seems to have been carried forward into macOS. I first noticed the problem with bluetooth audio dropouts (even without a mouse/keyboard) ever since I switched from Windows to a MacBook Pro in 2009.

On Windows systems as early as XP, I could use the built-in bluetooth card in my Tablet PC to listen to audio on my headphones, respond to type on my bluetooth keyboard, and draw with my bluetooth mouse, all without lag. An additional benefit is that when I received a call on my Windows Mobile phone, my headset automatically stopped the music on my computer to answer the call from my phone.

Since switching to the Mac and an iPhone, I find that the built-in bluetooth cards allow devices to be greedy and prefer to be the sole connection in use. Just as you noticed, devices work smoothly until you use an audio device. I searched for "Mac OS X bluetooth audio dropouts" and found numerous issues at the time. This problem even occurs on my updated 2015 MacBook Pro. The bluetooth pipe still doesn't seem big enough to manage the number of devices. Plus, even if I could listen to music on my new MacBook while working, the iPhone does not intercept the signal to take the call.

However, while I was at first disappointed at the reduced bluetooth functionality after switching to Mac, I learned to enjoy the power and reliability of the rest of the ecosystem. I think I'll try one of the other suggestions to add a different bluetooth device, and see if that works to improve performance.

I was having this exact same issue. I have a Macbook Pro (15-inch, 2016) with touch bar. I first noticed that I would lose connection to my mouse when I was using my Bose QC35s. I recently got a new set of AirPods and I was having the same issue. It was driving me crazy. As soon as I paused my music the connection would be reestablished with the mouse.

I finally bumped into this Forbes article (link below) today and it seems like it finally solved my issue. Unfortunately I can't use the handoff feature on my Mac anymore but it's definitely less of a problem than not being able to wear bluetooth headphones and use a bluetooth mouse at the same time (I'm using the Logitech MX Master mouse). I hope Apple jumps on this issue and fixes soon. This was SO annoying. I've been struggling with this issue for MONTHS.

Fix: Basically you just have to go to System Preferences -> General -> Uncheck "Allow Handoff between this Mac and your iCloud devices"

I've been using a magic keyboard 2 and magic trackpad 2 with my 2016 MBP with no problems. It's only an issue when I try to add my recently purchased AirPods. I don't think the problem is # of BT devices.

Well I submitted a bug report through my apple developer account and the engineering team closed my bug and marked it as a duplicate, so at least they are aware of the problem. My guess is we will never see a fix for this though.

I have the LG 27UD88-W. Even without the display connected it still happens, also on my 2015 imac at home it happens... it's a shame you can't use 2 great bluetooth devices at the same time...

It seems to be somewhat better since 10.13.1. I've also tried using just one AirPod, as I'm not sure if that is 1 or 2 BT connections. But not fully resolved. Mostly just less frequent.

The problem you are having is that the mac Bluetooth can't use both at the same time and is meant to only have one device connected at a time, try going and getting a wireless keyboard with a USB bluetooth piece to connect it to your computer. But overall your mac can't connect to two bluetooth devices at the same time.

I'm having the same issue, different hardware though

MacBook Pro 15'' 2017 Touchbar + Logitech MX Master + Plantronics BackBeat Pro.

This is insane!!! I had absolutely no issues with the same peripherals and my previous Macbook Pro 2014 model. Instead of advancing, it seems to be going back :/ Sad thing!

Also, this is an almost $3,000 computer!!! How is this even an issue?

Is there anyone from Apple willing to give us an answer?

I'm experiencing a problem that seems very related.

To me it seems like there is a problem when using bluetooth headphones and wifi.

I wrote a long breakdown here:

Re: tbMBP 13" bluetooth issue

To isolate the problem:

Have you tried turning off WiFi completely, and then use both Bluetooth mouse and Bluetooth headset at the same time without any problem?

Any updates on this? still having the same issue....

Just wanted to chime in and say that I have the exact same problem. Both the Logitech MX Master and the Microsoft Surface Ergonomic keyboard stop working when i used my QC35s

Could you share which display you have. I'm having the exact same issue, haven't tried without my display connected yet, tho

I put my comment by this link Re: Bluetooth not working High Sierra

I'm using the latest version of High Sierra. It did not make a significant difference. Audio dropping is a very annoying issue. It is not acceptable to have any drops.
