FabianZettl Posted February 4, 2021 Author Share Posted February 4, 2021 (edited) Thanks for the latest EFI, it's still the same error in the Bootlog. What can I try myself? different boot-arguments, or kext? As I use Lilu and whatevergreen, framebuffer should not be needed? SMBIOS of iMac15,1 is fine too and no problem?

sok5 Posted April 6, 2021 Share Posted April 6, 2021 I finally got my Z800 to work with Big Sur 11.2.4. I first installed Big sur with Asus x75a laptop and moved installed harddrive to z800. Only one thing, I couldn't got to work my ethernet ports. I have to buy PCI-e Fenvi t919 for wifi.

Chris1212 Posted May 4, 2021 Share Posted May 4, 2021 (edited) Hello, I have a: HP Z800 2 x 2.67 Ghz 6 Core Intel Xeon (x5650) Quadro 4000 2 GB Video Card 48 GB Ram It has been running Sierre 10.12.6 for quite sometime, but I was interested in upgrading to the latest stable MAC OS. Can anyone tell me what that would be and also if you have any insight on how to make that update? Should I use the up date or a clean install? Any help would be appreciated.
