Thank you! It worked
I've followed the tutorial until after the part of video
I copied the EFI for 300 series -> updated config.plist with HD 630 tags -> rebooted
I did't install clover, my motherboard is UEFI. i've updated SMBIOS with iMac i7 8700, since my specs are so similar. But sometimes animations get laggy, launchpad for instance. Safari tabs get weird when I pass the mouse over them.
Is there a way to improve this? Maybe my video config isn't correct ?
Left my config.plist attached
config.plist.zip
