MacBook Pro freezing every hour… Help please!
I have a MacBook Pro 13", 2,3 GHz i5, A1278. It work fine from a month ago when it started to freeze completely after 1 hour working. I turn it on, it work well for 1 hour. After 1 hour exactly, it freeze completely and i only can shut it down by pressing on/off button.
I try to change RAM or to reinstall OS (because off 1 hour limitation working time i can't install last version), but no result...
Have you any idea from where come the problem and how i can solve it?
