I didn't have luck .... again My BIOS doesn't have options for disableing integrated graphics nor nVidia, neither option to specify how many MB I wanto to give to HD4000 I don't know how this is possible, but it is like that Now I'm downloading App Store untouched dmg 10.8.5 OS X from torrent, and will make bootable USB by the guide above again, hoping I'll have more luck with 10.8.5 than with 10.9
I tried and, again, no success ( I constantly get message "WARNING: IOPlatformPluginUtil : getCPUIDInfo: this is an unknown CPU model 0x3a", just like in my last post with bootload screenshot here Is there any kext or other way to go around this error message? I have Intel® Core™ i5-3210M CPU @ 2.50GHz (Ivy Bridge).
I tried now to edit SMBios.plist and inserted SMcputype to thevalue suggested for Ivy Bridge CPU, but no luck, again the same message. It seems that I must wait for iAtkos 10.9 release, hopping it will work
