hey guys, ive been using my 2011 13 inch pro for the past 2 weeks. Its in FLAWLESS condition. I went into the apple store today cause i needed to reformat it (asked this question here but long story short, i lost my OEM disk). When I picked up the comp 45 minutes later I didn't have a chance to check it out cause i was late to a movie. After the movie, i thoroughly checked out the comp and i saw one blemish that im 90 percent sure that they made it. I checked the computer before i dropped it off and it wasn't there so either they made the ding or the charger did when i put it in the box, but still. im assuming they made it. is this damage small enough to get over or should i go back and complain. im just afraid that its so small that they can say it was my fault. its that little dent on the black part. i can't lie, im kind of sad that i gave them a pristine comp and got back a comp with a ding (albeit a teeny mark). my second question is about hidden or any other prevent thief mac type programs. i installed the program on my comp and uninstalled it but im a bit paranoid that it left traces inside the system files. i want to completely get rid of it. do you guys think it'll be completely gone if i do a low level reformat (the lowest type of erase that takes like 2 minutes and not the zero out data stuff) or do i have to do the heavy duty erase. i want to start FRESH, no traces of any programs. have all my data backed up on time machine. will a low level wipe do that or will low level wipes leave pieces of data (which i assume is why people say to do the multiple pass erase)? sorry for the noobish questions. added a poll so u guys can make fun of me edit: forgot to add why im paranoid about traces. if i do put a "firmware password" does that prevent me from installing/reformatting in general or does that mean when i reinstall snow leopard, it won't be fresh and would have traces of the app and still be active.
