Just wanted to confirm that installing that kext using KextBeast after a clean install of OS X had it working out of the box. Thanks so much for your help!

Guy's,

I have got to the stage where I have the Bluetooth device showing up on the USB port as:


BCM20702A0:


Product ID: 0x216f
Vendor ID: 0x0a5c (Broadcom Corp.)
Version: 1.12
Serial Number: 1008B1FFCE8C
Speed: Up to 12 Mb/sec
Manufacturer: Broadcom Corp
Location ID: 0x14b00000 / 4
Current Available (mA): 500
Current Required (mA): Unknown (Device has not been configured)

I have BrcmPatchRAM.kext installed with Kext Beast. I did this as part of the install of my wireless. If i am reading this correctly I need to run the yosemity installer again. Can you confirm. I have a 99% working T440p and I don't want to break it!!

If there is a more complicated way I fine with that!!


Thanks,

Ian.

Make sure you install correctly. It is covered quite clearly in the README.

Hint: BrcmPatchRAM.kext is not adequate by itself.
 
RehabMan,

Yep I can now see the firmware getting loaded in the Log:

The 22 second processing time is a problem.

Download patchmatic: https://bitbucket.org/RehabMan/os-x-maciasl-patchmatic/downloads/RehabMan-patchmatic-2015-0107.zip
Extract the 'patchmatic' binary from the ZIP. Copy it to /usr/bin, such that you have the binary at /usr/bin/patchmatic.

In terminal,
Code: 
if [ -d ~/Downloads/RehabMan ]; then rm -R ~/Downloads/RehabMan; fi
mkdir ~/Downloads/RehabMan
cd ~/Downloads/RehabMan
patchmatic -extract

Note: It is easier if you use copy/paste instead of typing the commands manually.

Post contents of Downloads/RehabMan directory (as ZIP).

Also, post ioreg: http://www.tonymacx86.com/audio/58368-guide-how-make-copy-ioreg.html. Please, use the IORegistryExplorer v2.1 attached to the post! DO NOT reply with an ioreg from any other version of IORegistryExplorer.app.

And output from:
Code: 
kextstat|grep -y acpiplat
kextstat|grep -y appleintelcpu
kextstat|grep -y applelpc

Also, post EFI/Clover folder (press F4 at main Clover screen before collecting). Please eliminate 'themes' directory, especially if you have an overabundance of themes installed.

Also post output of:
