I'm having this problem since forever : "Still waiting for something (root device )"
I read on his forum that I need some AHCIinjector (or something like that), tried it and the problem persists, and sometimes I get a kernel panic with the applepowermanagement kext, so I thought that the smbios file isn't correct (tried all kinds of macs from 2009 till now), still have this problem.
I used -f -v.
But, I already tried to install Mac OS (ML) using Clover and it worked (even if I had to plug the usb where Clover is installed each boot), and I tried the same procedure and it didn't work (same kernel panic above). Should I delete this kext or download a patched one?
-x flag gives me directly a kernel panic!
For Information: The usb led goes off during the boot (that's why it is looking for a root device) , and I tried the USB 3 kext (a generic one) and it gives me the kernel panic above but the usb led is still on!
