I am an Apple enthusiast and former employee. I now work repairing liquid spills, physical damage and doing component level repair to all Apple Products.
I have only recently started posting on ifixit, but hope to offer helpful insight.
I currently own an iMac, Macbook Pro, iPhone 4, iPad and Apple TV 2. I also have a strong background fixing software related issues and I'm hoping to shed the light on the much dreaded system folder.
