thanks, I went ahead and installed the kexts option from the EDP, and rebooted, and it appeared to boot, but the screen just went to black. I booted with the -v option and it did not hang, but went to the splash screen, retrying in safe mode right now. is there a doc or link with which EDP are good with what update of the OS? I saw on the wiki page where it listed models with what EDP, but I could not figure out what if I just had 10.6.0 on my d620?
