Hi, I received my Aluminum MacBook about three days ago. So far the experience has been amazing. However, I just found out today that 802.11n is not enabled on my MacBook. I do understand that extra software is required to enable 802.11n. The problem is, I have an AirPort Extreme 802.11n Router and I installed the utility, and everything included on the disc that it came with, on my MacBook. Why is my 802.11n not working? If I buy the enabler from Apple's website for $1.99, can I trust it to work? Has anyone enabled 802.11n on their Aluminum MacBook yet?
