In August I left my MacBook in a foreign airport. Fortunately my friend was in the same city and picked it up from the lost and found there. When I got it back a few weeks later the LCD screen was massively cracked such that the bottom two-thirds of the screen was black. My friend swore he hadn't dropped it, but he hadn't opened it up to check if the screen had already been broken. Of course I wasn't going to pay the ridiculous amount Apple charges for replacing LCD screens so I ordered a new one online for about $100 and did it myself. About a month later I began experiencing serious kernel panic issues to the point that it was occurring twice a day at least. I called Apple but none of the solutions they proposed, short of wiping the drive, worked. Finally about two weeks ago the computer started refusing to start up, displaying a progress bar on the gray start-up screen that never moved and then disappeared, leaving it to just hang interminably. Fortunately I had a backup from a few days before, so when I took it to the "Genius" Bar and the employee recommended that I do a fresh reinstall I used Time Machine to restore most of my files. Unfortunately the kernel panics came back immediately and two days after that the progress bar of doom returned. I took it back to the Apple store and they shipped it off to some repair depot yesterday, saying that the problem was likely with the hard drive or RAM. Today I get a call saying that my third-party LCD screen was "failing to pass their tests" because it wasn't Apple-sanctioned (??) and I would have to pay the full $755 for the whole Apple song and dance to get a new LCD before they could address the issue of my computer not starting. This seems to me to be nothing more than an attempt to wring me of as much money as possible from this ordeal. Any suggestions, please?
