<< Solved >> Booting Time - Dell Inspiron 7548

[PacMan]

Hello,
I have updated to macOS Catalina 10.15.1 successfully but it takes more than a minute to boot to the system.
Checking the output of the boot process the line
AGDCC: Unauthorized client 'PerfPowerService' (IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/IGPU@2/AppleIntelFBController/IntelFBClientControl)
was the one hanging the screen. After 50s+ on this line it continues the boot to macOS normally.

Any idea of what might be the issue here?

This is the screen on which it hangs for 50s

And here is when It proceeds normally

Hello,
For anyone there having the same problem, I solved it by replacing BrcmPatchRAM2.kext with BrcmPatchRAM3.kext and adding BrcmBluetoothInjector.kext. Did not know they had to be changed for 10.15.

Thanks

Thanks for that! I installed Catalina a while ago and had the same problem it took like 3 minutes to boot or something...

Now that I know this I'll also upgrade to Catalina!

Thanks for the infok PacMan.
But I’m at a loss finding where from to download BrcmPatchRAM3.kext and BrcmBluetoothInjector.kext. Can’t seem to find the release section on github acidantera. Could you help me?
