Works on MacOS Catalina, Big Sur and Monterey
This is the Hackintosh EFI Folder for Dell OptiPlex 9020M (only Dell OptiPlex 9020M). The configuration settings support MacOS Catalina lastest, Big Sur lastest and Monterey lastest with resolution up to 1920x1080. HiPDI support can be actived with One Key HiDPI script. You will have to generate a new SMBIOS before login to your iCloud account and need Map USB so that you won't have any problems with the usb ports when installing.
Also, if you install Catalina you should use SMBIOS iMac14.3. If you install Big Sur, you can use SMBIOS iMac14.4 or 15.1. If you install Monterey, you need to use SMBIOS iMac16.2. I recommend installing Catalina or Big Sur for the smoothest experience.
