My Macbook Air mid 2013 model randomly wouldn't turn on a few weeks ago. I eventually got it back on by pressing the on button a few times. Had to use this little technique for a few weeks. Then one day my mac decided it won't turn on at all. About a week later and after I had a techy friend look at it, I could turn it on. Then again today it won't turn on also. I'm not at all technical with mac as I'm a newb, but would you guys have any idea what the source of the problem could be? There is no interruption with the led light on the charger etc. Please help as I'm a film student and rely on my mac for final cut and final draft!!!
