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.
Got a tip for us?

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 downloaded the update but i'm afraid to install it/ restart my mac. so does it actually download anything during the installation process ?
