that may be why then

I have other OC EFI now 0.5.5 and work, but I can't upgrade to 0.5.9

I have other OC EFI now 0.5.7 and work, but I can't upgrade to 0.5.9

ahh well done

also FakePCIID.kext doesn't actually do anything on it's own, so you can remove that

Thx for help. I copy all kext from Clover... Now I will try copy SSDT-6x0G1h.aml to OC on first post and make OC Snapshot.

Feartech thx again. I try very hard to run 0.5.9 on my Probook 650 G1 and "maybe" now is done. If someone ask to test or make guide I post my EFI (is need to generate GenSMBIOS only). And don't update VoodooPS2Controller.kext

I can’t make it work.

try a usb2.0 stick/flash drive

try all ports on laptop

 

[alespardo]

I do now with an usb 2.0 and a 3.0 on the usb 2.0 port and the 2 ports 3.0 and the same results.

Maybe this solve the problem?

It's impossible to boot macOS Catalina, everything on my setup seems to be fine ?

For some reasons macOS Catalina doesn't boot if your system doesn't have a proper EmbeddedController (EC) device,
If your device has one named to EC0, ECDV, H_EC don't rename it, instead provide a fake EC device with SSDT-EC
Other case if your laptop or desktop doesn't have any EC device at all just provide the SSDT-EC to inject fake EC device.
Keep in mind that you need to provide the path that your laptop or desktop have so SSDT-EC matches your DSDT.
You can find the SSDT-EC sample here: https://github.com/acidanthera/OpenCorePkg/blob/master/Docs/AcpiSamples/SSDT-EC.dsl
