Hi, Try the Opencore bootpack i compiled for Vostro 5568 here:- https://osxlatitude.com/forums/topic/9995-dell-vostro-5568-sierra-high-sierra-catalina-big-sur-monterey/ It should be compatible with any kaby lake laptop. Cheers!

Flyingfishfinger, What kind of payload u have on that coreboot? Is it an EFI bootloader?

Flyingfishfinger, Interesting that u are using coreboot? Any particular reason as opposed to the stock bios?

Hey EVH, I would suggest to use Clover. Im also assuming that it is the intel version? Install Clover (find 5108) with options on "Install Clover in ESP", "Boot Sector - Install bootaf in MBR" and "Clover for BIOS Booting - SATA". Then replace the EFI folder with one attached. It has minimum kext to get things up and running. Reboot and select the installer or hard disk to boot. I tested this with Mac OS Lion 10.7. Regards. EFI.zip

Very nice. Love it when these old machine with mac is still relevant and somewhat indispensible!

Hey EVH, EDP has reached its "end of life" cycle some while ago. You can use clover (so far tested till 5070) with only config.plist mainly for MBP5.1 smbios injection, DSDT.aml from old EDP and minimum 10.7 32 bit kext to boot the install and main system. I just last week put back mac os lion life on my old dead D520 but with more modern bootloader LOL Regards.

Check in your System Preferences under Trackpad and see if gestures are enabled. Basic 2 fingers gesture should be working.

Fine tuning a hack to squeeze every little performance out of it is quite a feat in itself

@jantestmac Do something like that and see if it shows DGPU and maybe post the screeshot

Use IORegistryExplorer app which Jake pointed out in earlier post. In the app, find anything that resembles dGPU.

@jantestmac what kind of battery life are you getting with windows previously?

battery life is dependant on minimising power hogging things. disable whatever devices that you dont need also set your brightness as low as u can comfortably read and work also refrain from running too much stuff in the background oh also try to use the m.2 sata drive as opposed to mechanical drives. they are more power efficient. just some few tips to prolong your battery life

Yes. Big Sur bootpack is compatible with Catalina. U dont need to check codec. Just try the different value that Jake mentioned. The VoodooHDA.kext auto detect thats why its better for beginner but may not work flawlessly on all system. Regards,

Dear @jantestmac U can download the bootpack that uses AppleHDA.kext. U can change the layoutid in config.plist boot parameter using Opencore Configurator under nvram sections. U also need to clear nvram when u reboot. Cheers!

Hey @jantestmac Great to hear that the bootpack is working for you. As for the headphone jack, I suspect its due to it being both for headphone and mic i.e. a mobile handsfree kit could be used with with both speakers and mics working on windows. Will need to look into this further. Cheers!
