First off I want to say thanks everyone who reads my blog, I am glad people actually care what I have to say and offer. :)
secondly. In the first step of common issues to resolve I am going to go over 2 common issues I noticed.
1. When installing myhack from usb installer, I noticed that people just get a blinking cursors. please make sure your usb stick has the partition format of MBR. Click on the partition Tab, in disk utility, then click options.
Most USB sticks don't come with any scheme. This should solve the majority of people with that issue.
2. Second quick fix for graphics issues.
Make sure to use graphics disabler when installing myhack to usb
remember dual cards work, But sli, and crossfire do not.
ATI users, you rely on netkas.org
Nvidia users should be fine with just the GraphicsEnabler=Y section in the com.apple.Boot.plist.
Another option is to use efi strings (see my dual card tutorial as it applies to one card as well)
Another option is to edit DSDT. And the 3rd is to use NVenabler.kext
Personally the GraphicsEnabler is probably the cleanest. I personally Use efi strings for my dual cards.
The first 3 options are the same, except for NVenabler which offers some additional features over just "injecting"
Last but not least. if you run into gfx issues (garbly screen, black screen at boot)
Boot with -s flag (single user mode)
type:
mount -uw /
rm -rf /System/Library/Extensions/NV*
rm -rf /System/Library/Extensions/ATI*
now you will need to reinstall those graphics kexts eventually. but at least you will be able to boot. try that only as a last resort if safe mode (-x flag) does not work.
