Im having two issues trying to get the graphics to work properly on my x220. the one I have has the m620 i7.
I just dont understand the steps in performing step 1
1. Add/Install DSDT Injection for following key
"AAPL,os-info",
Buffer (0x14)
{
0x30, 0x49, 0x00, 0x14, 0x14, 0x14, 0x08, 0x04, 0x00, 0x00,
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0xff, 0xff, 0xff, 0xff
And as well as I having trouble updating to 10.8.2 it hangs after the bluetooth command line, but there is no bluetooth installed and also disable in bios.
I used the same exact install that was described in the beginning.
I was able to use the attached kexts to get the battery meter to work on 10.8
THanks!
