Moderators carlo_67 Posted 16 minutes ago Moderators Share Posted 16 minutes ago Is the resize bar enabled in the BIOS? Also run a CMOS to force detection and reset the NVRAM on the Mac, reboot from Mac and see what the card says under Information/Graphics and Monitor. Basically, it should see it. I get an error without WhateverGreen.kext. however it is the 4090 that predominates the slots, you have to try to temporarily remove it and try only the 6600 in pcie 1, once the mac is started insert it in the device properties of Opencore and put the boot arg nv_disable, put them back as they are now and try to start Link to comment Share on other sites More sharing options...
