Hello, I purchased a new macbook pro back in 2013 from Apple and has been working perfect up until last week! It keeps freezing randomly, sometimes on bootup at the login screen and sometimes randomly when watching movies or browsing the web. Turning it off and on gets it back on but I decided to format it (back to mojave) and unfortunately same thing, it even did it on the install... So I rolled it back to the OS it came with which was mavericks, did it there as well I have tried the clear nvram combo and the battery reset combo too but it doesn't do anything. I formatted it back to mavericks, then updated to high sierra and was fine for a week but its doing it again so I am stuck to what the problem is, do you think it's just given up on me after these last 5 years? Is there anything I can do. Thank you in advance.
