Help: Bluetooth stopped working

Bluetooth stopped after patch on MacBook Pro Retina 2015 to use Sidecar - is there a solution without changing the board?

Hi guys,

I’m facing a problem on my MacBook Pro Retina 2015 (A1502/A1398).

Recently, I used a patcher to release Sidecar, since this feature is officially not compatible with 2015 Macs. After applying the patch, I was able to use Sidecar with my iPad for a while and everything seemed to work fine.

After a few weeks, the Mac’s Bluetooth died completely. The system utility shows:

• Address: NULL

• Status: Disabled

• Chipset: BCM_4350C2

• Firmware version: v0 c0

• Transport: USB

I’ve already tried all the suggestions:

• Reset PRAM, SMC

• Commands in the Terminal (sudo pkill bluetoothd, removal of .plist)

• Delete preferences, reinstall macOS

Even so, nothing works again.

I read that this type of error usually indicates physical failure in the WiFi/Bluetooth (AirPort) card, especially when the firmware is in “v0 c0”. But before investing in a new board, I would like to know:

**Did anyone go through this after using patcher to release Sidecar?

Is there any way to recover the Bluetooth without changing the board?

Or, when it comes to this scenario, really only the substitution solves it? **

If you have tips on buying or exchanging this board, or success/repair reports in this specific post-patcher case, thank you very much!

Thank you!
