Multi Boot Success Hackintosh, Z390 Designare, i9 9900k, 5700XT, Stable and Fast [ Work/Play ]

Finally a working and stable Multi Boot Hackintosh: [ Mac OS Big Sur 11.6 , Monterey 12 Beta 6 , Zorin OS 16 Pro , Windows 10, Windows 11 ]

It was a hassle for few days to get them all on Opencore Boot menu etc. I'm very happy with my Opencore switch from Clover [ 1year]. Opencore is so clean and fast, drastic difference. I was able to update my Big Sur from 11.5.2 to 11.6 without issues after upgrading Opencore to 0.7.3 and kexts to latest. As recommended by others here, I did a fresh install of Opencore and backed up my files to iCloud Drive from Clover before formatting.

I followed the amazing Dortania guide: https://dortania.github.io/OpenCore-Install-Guide/ and for USB mapping I watched some Youtube videos [ Tech Labs ] just to get an idea visually. I recommend you follow the Dortania guide to the letter and don't assume anything is optional unless it says so. It will take some tweaking and repeat testing, which is the nature of Hackintoshing anyway.

I'm on Opencore 0.7.3 , I was first on 0.7.2 but had random freezes, after upgrading Opencore it seems stable so far. USB mapping also helped fix my freezes. Also very important if you have 2 Opencores EFI isntalls, make sure you are running the right one directly on that drive, I found out that for example Opencore from Monterey drive was running my BigSur which creates freezes [ You can make 2 different Themes to know which one is active ] etc.

My EFI structure

PS:

If you need my EFI for a similar config, I'm ok to share. However from my experience it's better to build yours from scratch and use other EFI just to compare etc.

I will be making a complete guide about this Hackintosh and comparison with M1Macbook Air and M1 Mac Mini on my Youtube channel: https://www.youtube.com/minimalnerd as promised in my previous post [ I had Covid related personal issues so I apologize for the delay]. Much thanks to this amazing community for the help and the suggestions 📷
