So My Macbook Pro is experiencing a few problems 1.The other day I went to turn it on, but the screen & Keys would not come on. I tried everything, Starting in safe mode,Starting in Single user-mode with command /sbin/fsck -fy, Neither worked. So I typed in the command Reboot & it started up fine. Now today it started again & I did the same thing. Whats going on here? 2.My Macbook keeps freezing up on me were I have no choice but to hit the power for sevral seconds until it turns off 3. Everytime I shut my mac down My trackpad settings go back to default. So I have to change them back everytime i get on Anyone else having these problems? What should I do?
