Hi, I bought my MBA a few months ago and I noticed the creaking about a month in. It seemed to be getting worse so I ordered the 5 point pentalobe from ebay under the suggestions of many on the forum. I never got around to fixing it as I was traveling a lot at the time. When I finally did, I noticed that the screwdriver did not fit the screws. It was definitely too small. And if it somehow did and I felt it wasn't, it still has not fixed the problem. http://www.ebay.com/itm/MacBook-Air...ltDomain_0&hash=item2a0f534c4d#ht_1588wt_1003 That is the one I ordered. I contacted the seller and they said they sent me the right one. It even said it on the packaging. Is this for sure the correct screwdriver for the 2011 13" MBA? Will any 5 point pentalobe screwdriver work? I would rather re-order the right tool myself and have it available for possible future use than to bother the genius bar on a sure to be crazy next couple of weeks. Thanks in advance.
