totobike Posted October 2, 2019 Share Posted October 2, 2019 Wifi/Bluetooth is working on Mojave and High Sierre, and only wifi is working on Catalina. I use BCM94352HMB wifi/bt card To make it works I have AirportBrcmFixup.kext in EFI Kexts and I add BrcmFirmwareRepo.kext, BrcmNonPatchRAM2.kext and BrcmPatchRAM2.kext in S/L/E For catalina, I can't copy in S/L/E because it's in read only, so I did it from mojave, I copied the three kexts into Catalina S/L/E but it is still not working. I have wifi but no bluetooth on Catalina. Do you have an idea for this ? Thank you again for all your help, you saved me !! Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 2, 2019 Moderators Share Posted October 2, 2019 Don't install to /S/L/E but install to /L/E instead. For Catalina, you need a different set of BRCM* kext patched for Catalina but should work on Mojave and HS too. https://github.com/headkaze/OS-X-BrcmPatchRAM/releases Download Catalina All version Install these 3 kexts to /L/E BrcmBluetoothInjector.kext BrcmFirmwareRepo.kext BrcmPatchRAM2.kext don't need BrcmNonPatchRAM2.kext What boot sound?

totobike Posted October 2, 2019 Author Share Posted October 2, 2019 Okay thank you, and can I use those 3 kexts on Mojave and HS too ? And on Mojave and HS, should I move those kexts from S/L/E to L/E ? Thank you again Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 2, 2019 Moderators Share Posted October 2, 2019 Test if they work on Mojave or HS too, I personally have not tested it.

totobike Posted October 2, 2019 Author Share Posted October 2, 2019 Yes I tried with just the 3 kexts in L/E and it works everywhere : HS, Mojave and Catalina. I've got a last question : I've got another dell laptop, E7440 (same config i7) and on the E7440 I have this wifi/bt card : Atheros AR5B195 Do you know if there are some kexts that work with the three systems too ?

Moderators Jake Lo Posted October 2, 2019 Moderators Share Posted October 2, 2019 For HS, a simple patch should work, but Atheros are not longer supported under Mojave and I doubt for Catalina either. You might be able to get around it by using kext from HS but I don't know if there will be any repercussion. 1 Link to comment Share on other sites More sharing options...
totobike Posted October 2, 2019 Author Share Posted October 2, 2019 Okay, I used kexts in L/E and yes it was working for mojave too. But sometimes the bluetooth was not working, it was working again after reboot. Thank you again for all your help. It's really great you found me full of solutions. Thanks for all that work, you're awesome !!! Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 2, 2019 Moderators Share Posted October 2, 2019 With the new files, does Fn+Arrow key works for Brightness slider? Link to comment Share on other sites More sharing options...
totobike Posted October 3, 2019 Author Share Posted October 3, 2019 Hi ! I just tried now and it's working but the two arrows increase the brightness. I can't decrease, I can only increase with fn+up or fn+down. But fn+f3 and fn+insert are still working good. Maybe that is because I used an old voodoo keyboard kext ? The one that you gave me in EFI wasn't working... I will try it again and I tell you if it changes something. Link to comment Share on other sites More sharing options...
totobike Posted October 3, 2019 Author Share Posted October 3, 2019 I have a new problem on the three systems, there is a problem with the bluetooth, I can't connect my bt mouse to the laptop, the bluetooth is switch on but I can't find the mouse or I can't connect to it when it appears. Have you got an idea for this problem ? I tried to add my old kexts in S/L/E and it is not working since I have the new EFI. So I put your 3 kexts again in L/E. The only way to connect my bt mouse is to switch off and switch on the bt with the physical power button on the laptop. After, and sometimes, it connects correctly to the mouse. I changed the batteries, I tried to remove and put it again, I tried to switch off/on the mouse. Link to comment Share on other sites More sharing options...
