    i wanna update but i'm afraid that it requires me to download anything from the internet during the installing process and the internet at my place isn't reliable right now due to the weather. So, if you updated... does it require me to download anything additional form the internet during the installation process? how many Mb? Thank you.

    Then wait for the weather to clear. I ran the update last evening on my MacBook Air, took about 5 minutes total and went without any problems. BTW it was overcast but not rainy when I did.

    I doubt it would download anything during the firmware upgrade. The firmware is applied during a reboot and doesn't even have access to network resources at that point.
