I reinstalled (and replaced the AppleACPI kext) it and tried -v -f and now it panics at AppleIntelGMA950.kext. MyHack doesn't work fully for whatever reason so I used xfail, having placed the extra folder on the flash drive beforehand, then used MyHack to install chameleon which works. If I install MyHack utilities, the install blacks out after the destination select screen. Do I need to use MyHack to install the extra folder? I didn't when I made my 10.7 USB without error. I have also tried using graphicsmode to no avail.
