GOOD NEWS for macbook pro 2010 with BCM94331PCIEBT4CAX upgrade.
Osx El Capitan 10.11 Upgrade form yosemite today
I don't have modify bluetooth kext, just AirPortBrcm binary.
typed in terminal:
ioreg -l | grep "board-id" | awk -F\" '{print $4}'
show for my mac: Mac-F22586C8
and so i have manual edited the AirPortBrcm4360 binary and i have added my Mac-F22586C8 Board-id
Now This is what you have to do:
Reboot using CMD+R
Open terminal
Type: csrutil disable
Reboot
1. application/utility/terminal, write: sudo nvram boot-args="kext-dev-mode=1"
2. open Kext Drop and drag on it my IO80211Family.kext
3. This is the end: reboot your macbook, now we have all new functions working.
If not, try to log out iCloud from macbook and iphone and then login again
I am not sure if all the step are necessary, I am a regular apple user, not an expert.
I hope you can solve like me
This modded kext it's only for MacBookPro 2010 with BCM94331PCIEBT4CAX card upgrade
