Hi marcelvn,

And one more question, did your webcam worked on Mojave?

Catalina Update went well on my HP EliteBook 8470p. The only thing that doesn't work, yet is Bluetooth

Same here, HP EliteBook 840 G4, update from the App Store went OK, only Bluetooth is not working.

Wireless Card: DW1830

I tried to load firmware with this BrcmPatchRam fork (head to releases): headkaze/OS-X-BrcmPatchRAM

What I already tried so far:

load the 3 kexts in /EFI/Clover/kexts/Other -> leads to no bluetooth available

load the 3 kexts in /Library/Extensions [or load them both in /E/C/k/O and /L/E] then fix permissions and rebuild cache then restart -> BT shows and kinda scans devices.. but I cannot connect any device and something new I've noticed is that the physical BT indicator in my laptop flashes when it is scanning or trying to connect to something.



Handoff works...

BT firmware fails to load with kexts in /L/E I guess... Firmware Version: v5 c4096

Hello guys! I have an Elitebook 840 G5 laptop...
I added -disablegfxfirmware, because in the last restart of Install I got a Kernel Panic.
Catalina Update went well, but I'm without bluetooth (DW1560) and without sound...
I used the most recent AppleALC, but it's not working for now...

I updated it like a real Mac, using the Installer from the App Store, even though it took long (quite an hour or so), it works. What doesn't work is Bluetooth. I've already tried many things, but nothing helped and honestly I don't really need it, but you should keep that in mind. The first thing I've noticed was the pretty long boot and shutdown time (3 or 4 times as long as it was under Mojave). The battery seems to be okay, not much better or worse as ist was under Mojave.
I am using the BCM43225HMB (branded by AzureWave)

I can't help you with the Bluetooth problem (it seems that almost everyone has some kind of problem with Bluetooth),
but I may can help you with the sound. In my case, the update changed the injected Audio-ID. What I did :

1. update Apple ALC
2. changing the injected Audio-ID back to the number I used before updating
3. reboot

After that it worked.

I've noticed the long boot is due to the old BrcmRamPatch, replace or remove those 3 kexts and boot & shutdown will be normal again.

Well, it worked. Thanks.
But I've noticed something else. After I booted my System, it takes several Minutes till I can connect to or even choose a Wifi. Do you know why it takes that long?

I have directly updated my Hp Probook 4440s to Catalina.

Everything working expect Audio.

Anyone can please help me.
