Ripristinare mac os x 10.7.5

Restore a MacBook Pro OS X ≤ 10.6.8 NO DISK

Thus I am now in the same predicament as all these others, however, despite trying method one and two I am getting nowhere. I have had to reboot from Timemachine which of coarse puts me back to the old password. How can I get my desktop back after resetting the password without having to reboot with time machine? All lead back to gray screen unless I spend hours letting it reboot with time machine. Apple says i have to bring it in to redo the firmware password, which is about 4 hours away i dont want to drive that far, again. I unknowingly setup parental controls on the only admin account.

Now there is no way to disable parental control or create another admin account. What can I do to get out of the tangle? I foolishly changed my sisters password and now I cant remember it. She is still logged in and can use her iMac, if I do method one and I log out will this work on a her comp? Although it show up for all other accounts. You cannot reset the password of a mobile account locally, it needs to be changed in the directory service to which the computer is bound.

Does it still work? Please confirm something. Because if not, that would mean disk encryption is useless. Without the password you would need the encryption recovery key which you should have kept in a safe place, but not on the encrypted hard drive—obviously. Considering how trivial it is to change a password in OS X, without even knowing the existing password, I would never run a system that has any personal or business data on it without using encryption.
