I have been fighting this laptop (MacBookPro11,5) for a year now with
linux (mainly on Thunderbolt and power issues), but this is one of the
last ones that remains.
The system contains a BCM 43602 (rebranded by Apple of course):

Basically when wifi is on a 2.4G frequency, bluetooth (my keyboard and
mouse) are erratic (all over the place) - mouse stutters and keyboard
loses / repeats keys constantly. In the past I have used atheros and
intel nics with their bt coexistent modes, but I do not see that
option for broadcom modules.
Is there a trick to getting them to play nice? At home, it is not an
issue as I use 5GHz bands, but many times at customers they only have
2.4 on their "vendor supported" APs for me to use, so my mouse is a
no-go (and I truly hate trackpads).
Thanks for any help, and I can provide any info needed. This seems to
be a common issue, but I do not see where anyone has fixed it or
posted to linux-wireless as of yet.
Thanks
-Greg
