Where did you find that the GPU and the WiFi cards in our laptops will work? Besides, I think all BIOS settings, except for UEFI boot are already as they should be.
the iatkos ml3u guide says...
- nvidia vga cards from G80 core to the newest kepler series (G80, G84, G86, G92,
G94, G96, G98, C79, GT200, GT215, GT216, GT218, GF100, GF104, GF106, GF108,
GF110, GF114, GF116, GF119, GK104, GK106, GK107) are supported on 10.8.3.
This does not mean that all of them will work (of course) but most of them will work
out of box (OOB) with iATKOS ML3U.
Some of them will work with issues (some are known issues and some may not be)
and some of them may not work. You will have to try and see it yourself.
- Common wired and wireless network devices listed below will be auto-detected by
iATKOS ML3U and most of them will work OOB.
- Users that have other compatible network devices will have to search for the drivers to
make them work on OS X.
- Intel Gigabit and Intel Pro/100
- Realtek RTL 8139/8111/8168
- Atheros AR8121/AR8113/AR8114/AR8131/AR8151/AR8161/AR8171/AR8132/AR8152/
- Broadcom BCM57780, BCM57781, BCM57785
- Marvell 88E8035, 88E8036, 88E8038, 88E8039, 88E8056, 88E8001
Some chips (ie. Atheros ar5008, Broadcom BCM4311) are natively supported by
OS X. So, this is not the complete wifi support list of OS X, this is the additional support
- Atheros 9285, 9287, 9227
- Broadcom 4312, 4321, 4322, 43224, 43225, 43227, 43228 (Some of these broadcom
chips need rebranding in order to work on OS X.)
maybe i said wrong about wifi.... but nvidia 500 series is "gf114"
