Hi all! I need your help! My OS X Mavericks has lost sound and I can't listen to anything with or without earphones. I tried to fix it at System Preferences, but no use. Then I restored my PC to factory settings, again no result. Now I think maybe it is a physical damage, because very often I used to push hard my earphone connector into the jacket and now there's no red light in it. IS there any place in Toronto where they repair physical damages? And how much would this cost? Thank you!
