Q: OS.X.6.8 fails reboot

Sep 28, 2014 2:17 PMby ligux,AppleJack??? I´m afraid not.
Just in case I check HDs , RAMs , Files, Volumes ... with Techtool and everything is OK.
Maybe a kind of files I should get rid of, to try it to make it work? Preferences? because it is not Hardware, and though I have fixed permissions sure it has to do with some corrupted file.
The only strange thing to be aware of, is that I mistook with an HDMI cable (ATI HD5770) , it went fine during the previous session to the blackout :-p ,but then ...
Thanks

At the prompt, you can then type "applejack AUTO restart" (no quotes, the AUTO in caps), and wait for AJ to do its job.

I have thought that maybe with a new clean installation of SL in another partition and launch everything from there might help, but gets the same problem , SL install DVD gets stuck. I have even tried a clean new installation from X.5.2 install cd´s, but it also get freeze with the the color ball spinning.
I am starting to think that there might be some kind of command that once installed Mavericks in any other HDpartition , blocks old installations.
Desperate for a solution

If it's a yes, then you're right, installing a more recent OS X version on your Mac created a recovery partition that essentially "brands" your hard drive as being Lion-and-above-only, so you'll have to wipe it out thoroughly before you can downgrade to SL (see here: How do I downgrade from Mavericks back to Snow Leopard?).
This said, your spinning beach-ball when trying to boot from the DVD leads me to think there's something wrong with your hardware, but I may be wrong.
Is the DVD you're trying to boot from also the one that came with your Mac, or a retail DVD? If you scavenged it from another Mac, it won't boot on another Mac except the one it's tied to (they are usually grey).
