I did. You have to edit BroadcomBluetoothHostControllerUSBTransport.kext inside IOBluetoothFamily.kext/Contents/Plugins in S/L/E. The file I attached is for 10.12.3 (16D32).

It gets overwritten after every update, so you have to change it every time you update the system.

1. Copy IOBluetoothFamily.kext from S/L/E to Desktop

2. Right-click the file and choose Show Package Contents

3. Go to Contents/Plugins

4. Find BroadcomBluetoothHostControllerUSBTransport.kext

5. Right-click the file and choose Show Package Contents

6. Go to Contents folder

7. Open Info.plist with editor of your choice ( I like Xcode or Brackets or PlistEdit Pro, don't use TextEdit)

Choose any of the controllers listed and change idProduct and idVendor integers to look like this:

<key>idProduct</key>
<integer>1</integer>
<key>idVendor</key>
<integer>2578</integer>

(just replace the existing numbers with 1 and 2578)

Save the changes.

Install this new kext using any kext utility. I use EasyKext Utility. After restart you should have bluetooth working.

Morpheus NS,

I've inspected a file

/System/Library/Extension/IOBluetoothFamily.kext/Contents/PlugIns/CSRBluetoothHostControllerUSBTransport.kext/Content/Info.plist

and found that section you mentioned in your post is present there!!!

Could you confirm that this file also has mentioned by you section?

I've attempted to load this kext manually and system still reports "Bluetooth unavailable".

NOTE: At first I decided to copy BroadcomBluetooth.....kext into CLOVER/kexts/10.12 and substitude name from Broadcom to CSR -- and at this point I found that there is a kext with such name.

Further investigation of CSR kext gave me the section you included in your post. After this finding I assumed that loading this kext should activate bluetooth but it did not work.

Hervé,

I've followed your suggestion and inserted the section into my FakeSMC.kext/Content/Info.plist -- after reboot the system had a progress bar on black background and hang there for a while, then the screen turned black (probably the screen saver kicked in).

My guess is that as I use "extended" FakeSMC.kext (reports HDD, Video Card temperature and CPU freq/temperature) there could be some incompatibility with FakeSMC.kext.

I wonder what would involve to make a "stand alone" kext for this module.

I looked at following webpage and due lack of knowledge in this field I do not know how to do it properly

https://developer.apple.com/library/content/documentation/Darwin/Conceptual/KEXTConcept/KEXTConceptIOKit/iokit_tutorial.html

I know that it can be done as it is done with AppleALC.kext module to support "unsupported" sound codecs (I use one of them ALC883).

It would be nice to have kext module for this inexpensive bluetooth module available under CLOVER/kexts and keep OSX untouched.

Hervé,

please see my attache FakeSMC/Content/Info.plist file.

With this modification I restarted the computer, Clover loaded up, I selected "El Capitan" and pressed "Enter".

On a black screen appeared white Apple and progress bar. The progress bar was moving close to the middle with high HDD activity and after that HDD activity stopped - the progress bar continued slowly move forward but system never completed to boot.

I booted from flash drive and removed "modification" to FakeSMC/Content/Info.plist file.

I am not sure why it works for you but not for me.

A few screenshots (sorry for quality) with an error caused by changes made in FakeSMC.kext

osx151212 · February 2, 2017

For reference, this issue is described on following web page

there is kext available on the page. I've downloaded and put under clover bootloader.

After reboot no bluetooth device has appeared in "System Information" but under USB Vendor ID and Product ID has changed.
Although the issue still persists it gives some basis for kext modification.

In description mentioned that there are a few versions of same device, on my check I found that I have Version 1.00 and Version 1.34.

NOTE: it seems that CSR works for some people at least in the past

There some way to do it from clover configuration in kernel and kext patches

hacker1024 · May 7, 2019

You can implement Morpheus NS's solution with Clover's patching feature. This maintains a vanilla install, and won't reset after updates. Paste this in the KextsToPatch section:

	<string>Bluetooth adapter fix</string>
	<key>Disabled</key>

I got it working under High Sierra by placing these three RehabMan kexts in Clover kexts 10.13 folder.
