Hackintosh-OptiPlex-7070-SFF

Opencore Bootloader 0.7.5. Tested on Monterey 12.0.1

Introdution

This is the Hackintosh EFI Folder for Dell OptiPlex 7070 Small Form Factor. The configuration settings support MacOS Catalina and Big Sur. Because deep sleep will cause a kernel panic, I blocked sleep in BIOS.

I'm using a iMac 19,1 SMBIOS to improve performance with dedicate GPU. If you only using the intergrated iGPU, set SMBIOS to Macmini 8,1 will avoid most of the issues with video.

You will have to generate a new SMIBIOS before login to your iCloud account.
