On my recently purchased macbook pro, the shutdown time had been about 4 or 5 seconds. Earlier this week, I plugged in a Sprint Smartview aircard to use for work. The card installed software to get it working. Since that moment, my MBP takes about 20-30 seconds to shut down. I have since uninstalled the software, hoping that it'd return to the 4-5 second shutdown. Alas, it has not. I've tried running ONYX and using the Disk Utility to repair permissions. Any advice on where to look or what to do to clean this up and get it back to the 4-5 second shutdown? I'm new to the mac world, please help.
