Bluetooth fails on OS X 10.10.2 #146

Closed spbriggs closed 9 years ago

spbriggs commented 9 years ago

I had this working with Yosemite 10.10.1 but lost Continuity with the update to 10.10.2

I have a MacBook Pro mid 2010 15" retrofitted with BCM94331PCIEBT4CAX card

I've done a restore from Recovery disk (with the -r option) and am left without functioning wifi but with working Bluetooth.

On running CAT compatibility check I get

Please see #139 which describes in detail what to do when an OS X update comes out. The best thing to do is just re-activate with CAT in case you lost Continuity.

In short: my understanding is that that you overwrote the new OS X 10.10.2 drivers with old ones from the recovery disk, that are incompatible with OS X 10.10.2. OS X updates don't necessarily update what's on your recovery disk apparently. The "-r" recovery option should therefore be used with care.

An immediate workaround in your case:

  1. Download and install Kext Drop.
  2. Go to your user directory>KextBackupAfterPatch. The patched OS X 10.10.1 kexts should be in there. Better yet : get a clean copy of the OS X 10.10.2 IO80211Family.kext.
  3. Open Kext Drop, drag and drop the IO80211Family.kext into the window. Click Install.
  4. Reboot, verify if your Wi-Fi connectivity is back.
  5. Re-activate with CAT.

Thanks for the pointers. I've reinstalled the OS 10.10.2 update from Apple and ran CAT again. All working perfectly now.

Thank you.
