Hmm. I’m experiencing similar problems for months! Haven’t worked out a solution yet, and it's killing my productivity.
I’ve also posted my break down in this support thread:
https://discussions.apple.com//thread/7780518?start=0&tstart=0&replyId=31081001
MacBook Pro 2016 with Touch Bar. Latest MacOS Sierra.
- Bluetooth Apple Magic Keyboard
- Bluetooth Apple Magic Trackpad
- Bluetooth Beats Solo3 headphones with W1 chip
- Bluetooth BeatsX headphones with W1 chip (same problem)
- Connected through WiFi 5Ghz network
I can use my setup just fine, listening to Spotify, doing work. Nothing is wrong. Other than my WiFi internet connection seems a bit unresponsive or slow at times. But then again, a few minutes later it works fine and speedy.
But...
When using my MacBook Pro to do calls (Skype with/without screensharing, FaceTime or Handoff calls using my iPhone) and my Bluetooth Headphones with mic to talk:
- keyboard starts disconnecting
- trackpad starts disconnecting
- sometimes even my headphones disconnect
- sound connection drops out for a few seconds
This is getting worse when I browse to any website during the call. I get an immediate drop.
It seems like it's something between wifi/bluetooth at the same time:
- wifi connection use, the more bandwidth I use, my bluetooth connection drops
- bluetooth two-way use. ACC codec (one way) less of a problem. SCO codec (two-way using mic during calls) more of a problem
My workaround right now, during calls:
- do not touch my bluetooth keyboard, or keyboard connection will drop
- do not touch my bluetooth trackpad, or trackpad connection will drop
- use internal macbook keyboard and trackpad instead
- do not use internet or browse websites, or skype/facetime/call connection will drop or go silent
When using my Bluetooth headset Beats Solo3, I noticed slower and unresponsive website browsing as well.
For me it looks like it definitely is something between WiFi+Bluetooth.
- When I disable bluetooth entirely in MacOS: internet is snappy and super fast.
- When I disable WiFi and use an Ethernet cable for internet connection, internet is super fast and bluetooth connections are sold, with no disconnection of my keyboard, trackpad or headphones
I haven't been able to easily reproduce with a few exact steps. However, it's happening every single day.
Trying to reproduce it on my older MacBook Pro Retina 2012 as well, but wasn't successful yet. No dropouts there. I do have iCloud enabled and use Handoff calls succesfully.
Anyone tried their same setup on the latest MacBook Pro 2017 yet?
