Hello, I have a MacBook Pro, it was working fine today, but when i got home and turned it on, it freezes on apple logo and keep playing 3 beeps.. I searched a little bit and i found out that this should be related to Memory Problems.. As i need my Mac this week, i prefeer to take to authorized support only in the last case.. anyway, i used the hardware test tool from apple (pressing D on the boot) and made the extended test, it said everything was OK, no problems found. I even booted a Live Linux distribution, Lubuntu 10.10, and it worked perfectly, so i really think thats not a memory problem.. maybe the SO is corrupted? I have a disc of MAC OS Lion and it boots perfectly, but i dont want to format the computer and loose my data.. I tryied to access from Linux but i receive a message of Access Denied.. Any sugestions? Is there anyway to me to access my User folder on Mac HD by Linux? Get permissions? How can i get permissions? Thank You very much!
