Hello !
I would like to address a huge Thank You because I successfully managed to install a clean Catalina 10.15.7 on my HP Z220. Since I use the HD4000 onboard graphics, I simply modified the Mac ID to "iMac13,1" and the adequate PCI value as described on the OC guide. It went OK on the first attempt !
Everything works perfectly (Ethernet, sound, sleep/wake, graphics acceleration...)
The only thing I notice is when I try a Geekbench 5, I am not super impressed with the resulting score: My score is 759 single core / 3032 multi core. I have a core i7 3770 CPU, which should be better than the iMac 2012 with i5 processors.
Do you think that this is due to:
- HP Z220 motherboard / lack of hardware optimisation ?
- Settings to tweak in BIOS ? (I didn't notice any kind of parameters related to timings...)
- Opencore limitation => Is there something to try in config.plist to optimise performance?
Thanks again for all that great work !
I'm very happy with my new Hackintosh !
