E7450 Catalina 10.5.4 - only partial bluetooth


Recommended Posts

debug_16132 2.zip

Hi folks, have installed Catalina onto E7450 using EFIs from this site.  Have used latest clover and updated key kexts, which facilitated upgrade to 10.15.4, which is all fine.


Wifi shows up and works

Bluetooth shows up on System Preferences and in top menu bar, but does not connect.  Was working fine in High Sierra and Mojave, so my chip is definitely Wifi & BT.  


Debug attached.  Anyone able to help?

In case you have missed it or have not been following Catalina updates, you need an additional kext for BT

BrcmBluetoothInjector.kext <- new additional for Catalina

BrcmFirmwareData.kext <- *Data for Clover kext or *Repo in /L/E

BrcmPatchRAM3.kext  <- change to 3 instead of 2 for Mojave

cool.  i had those 3, but had 'repo' in clover, not 'data'.  switching out appears to make no difference.


in /EFI/clover/kexts/other i have:-





in /L/E, I have nothing


any other ideas?   I can turn the BT on and off now, but it cannot see any devices.
