HP Z800 - Anyone working on this with current (0.7) OpenCore versions?


7 posts in this topic

Recommended Posts

Wondering if anyone is trying their HP Z800 with the latest OpenCore versions and Big Sur?

 

I searched the forums but only find references to some older work (and potentially around Clover not OpenCore).

 

Similarly, there is an EFI for HP Z600 but it's for a MUCH older version of OpenCore.

 

I'm getting nowhere fast but would be glad to share notes 😉

 

 

Open Core Install Guide
This is your starting point Don't look around trust your own self just do it
Read carefully each of the part
Open Core Sanity Checker
 
Big Sur from USB installer no go because apple drop support for ICH10 
But there is another way how to get Big Sur on unsupported hack and this is called
Emulated NVRAM
Another guide which will help you how to do that
 
  important thing is proper configure open core bootloader which can install macOS Catalina on your HP Z800

Thanks Rocky!  I'm very familiar with the Dortania guide (as well as the OpenGeek checker though that appears to have stopped being updated several revisions of OpenCore ago).  I've been bit by the "EXITBS" issue, despite painstaking process-of-elimination troubleshooting. (https://dortania.github.io/OpenCore-Install-Guide/troubleshooting/extended/kernel-issues.html#stuck-on-eb-log-exitbs-start

 

I'll re-read the Emulated NVRAM link -- I skimmed it but didn't connect it to the process mentally.

 

I'm going to take your advice and try Catalina instead of big Sur as a starting point.

 

Appreciate your feedback greatly!!!

So okay there are three different option for Bios Based machine
NR = 1 VMware method on any working macOS, you need separate HDD or SSD for it
NR= 2 macOS Image Restore Method
NR= 3 Emulated NVRAM can help you to upgrade from Catalina to Big Sur
Nobody is perfect until you put your hands on
If no one did that before, you could be the one
wish you all the best

Look here: 

https://github.com/topics/hackintosh?o=desc&s=updated

https://github.com/topics/opencore-efi

for updates to published efi's

 

Otherwise the principle is the same.  Start with a minimum of drivers and kexts and applicable ACPI .aml(s) for your config that follows a current guide for your hardware.  If you make changes do so one at a time.  csr-active-config 67080000.  Recent version(s) of Open Core may not inject some kexts with functionality while there can be no problem with the same kexts and booting with recent version(s) of Clover.

 

per your message here are some notes to share including how to avoid disturbing a working bootloder:
