Was on 1307 until 10.7.4. After losing x64 I moved my DSDT, updated to 1701, generated a new dsdt and patched 5 or 6 generic issues w/ the old auto patcher (discontinued GUI based front end to patcher). It's odd, I recall my system crawling w/o a proper DSDT (SATA/AHCI patch resolved this issue) however when I updated to 1701 and booted sans-DSDT it seemed to boot up normally.. wondering if I missed something or perhaps the issue no longer manifests on 1701.
Technically I'm not concerned w/ patching HDA or graphics. Using an external M-Audio as I got fed up rolling back AppleHDA and using a natively supported 6850 (technically using GraphicsEnabler to inject the correct ATI frame buffer though..)
Yes, I've used myHack many, many times over the years however the current install is a basic chimera (chameleon, stolen and rebranded) w/ manual kext management via CLI..
EDIT:
Okay, looks like typing another project's name results in "Stolen rebranded version of chameleon".. I get the point however it's still very passive aggressive. It injected the correct frame buffer for my 6850..
