Good day all, I purchased my MacBook Pro in 2009 with Snow Leopard installed as the OS X at the time of purchase. When "LION" was introduced, I backed my system up and loaded "LION" on. During the upgrade process, the software download and installation froze, which I found was common during this release. I powered the computer down and back up and the new OS X was loaded and ready to go. Ever since then and with all other OS X upgrades, my system has been slow. Safari loads extremely slow, startup takes as long as my company provided Dell and overall performance has been down. When I visited my local Apple Genius Bar they cleared some temporary files but didn't have any answers on what could be the problem. I asked if I should backup my Mac, reset the system completely, and then load only the most important files back on to my Mac. So, I realize i've dealt with this problem for awhile but it really is annoying and is not the performance I expect from my Mac and I'd like to fix this. Any help or advice would be appreciated. Thanks in advance.
