So I've been running el Cap on my X58a-UD3R perfectly (apart from shutdown since the day it came out, with no problems (apart from shutdown). I'm trying to install Sierra but the old boy won't let me - I've changed the SysDef to 14,2, but when I try to download from the App Store it tells me that:
This version of MacOS can't be installed on this computer. I've got enough RAM, sysdef is changed,a compatible graphics card (with the new Nvidia drivers) but...no dice.
Anyone got any clues?
