Dell Latitude E6420 ATG
BIOS A21 (Legacy)
Intel Mobile QM67 Express Chipset
Core i7-2720QM
8GB RAM
Dell Quadro NVS 4200M
Intel HD Graphics 3000
So I was able to install H/S 10.13.4 with your bootpack (Brilliant work and many thanks, btw) I have EVERYTHING functioning except full QE/CI from the Intel Graphics. Quadro registers 4095mb VRAM, Intel HD only 4mb with no kexts loaded. Ideas? Thanks a ton!
