[RetroAndDev]

Hello, in may, use your repo to create a MacOS Catalina Hackintosh (on dell inspiron 15 3583)
But 3 month ago i delete the macOSX of the drive (to use in a real mac)

I want to know if you have a succefull installtion and how you have created this installation
Tanks
(Sorry for my english, i a french student)

I was able to install Big Sur using the normal USB install method. As long as you are using the most recent OC from this repo it should be fine.

Ok, how did you get it installed from macOS big sur ?
Because my real iMac run macOS Catalina (10.15.3) and it’s a 2012 mac, Big Sur is not compatible on this machine

[RetroAndDev]

Finaly i try with Catalina (because i already make a the hackintosh in around of May 2020, but i formated the disk for a real mac)
Clover wont boot on macOS Intaller
macOS say : Attemping system restart....Mach reboot.
Did you have any solution ?
If you want the EFI or other informations, ask me

[RetroAndDev]

What SMBIOS did you use with OpenCore ?

ok thanks with persistence i managed to hackintosh under big sur but i have huge stability problem and the internal screen is not working. (To be precise macOS crashes on startup 9 times out of 10) do you have one or more solutions?

[jkcoxson]

I did not have that problem, so I'm gonna have to refer you to the hackintosh discord. They can help you better than I can. https://discord.gg/u8V7N5C

[RetroAndDev]

Ok I will try again with the latest version of the repo I will keep you posted
EDIT: Which version of OpenCore are you using in the November 30, 2020 repo?
EDIT2 : Now he boot normaly but the screen didn't work

Hello, I finally decided to go back to Catalina (10.15.6).
It works perfectly but did you find a fix for hibernation (cover closed = macOS in standby but screen still on) ?
Have a nice day

[RetroAndDev]

Hello,
I finally managed to make a hackintosh with macOS Catalina.
But I use Intel Graphics Fixup but the GPU (Intel UHD 620) only works with 7Mb of graphics memory, do you have a solution?

[RetroAndDev]

Hello, i make a MacOS big Sur Hackintosh but the integrated screen is not reconized, i use a HDMI screen to use macOS
Do you have a fix for this problem ?

[jkcoxson]

Hmmm, I definitely don't have those problems. The problem is that this laptop has UHD 620, which is pretty much the worst Intel graphics you can have since no real Mac actually had them. Your best bet is to play with frame buffers until it works.

Thanks for your answer, I will try but if you don't have these problems we may have a different bios configuration, can you send me yours?
Have you changed your OpenCore configuration? If yes, can you update the repo
Thanks
