hey guys so recently i got a scratch on my Macbook Air 13" (early 2014), and despite not knowing where the scratch came from as the device was only 2 months old, i had to accept it was my fault and so I recently paid $600 to repair the screen. I'm picking it up from my local apple store tomorrow and I wanted to know how to keep scratch free. i did not have a screen protector, and used the MONSTER ScreenClean with the Microfibre cloth to cleen the screen and kept it in a case in my bag. so if you guys have any reason the scrcth couldve occurred and how to keep it scratch free, it would be most appreciated. note: the scratch was very long, and covered half the screen thankyou!!
