Hi all. I still consider myself a Mac newbie even though I "switched over" a little less than a year ago. I'm a late adaptor, so I just upgraded from Tiger to Leopard10.5.6 yesterday. I was nervous about doing it, but the upgrade was easier than I thought (cloned/backup Tiger to an external Firewire HD, fresh install, and then used Migrate assistant to bring back all my apps and files) However, I noticed 2 things: 1) my wireless internet connection isn't working 2) Leopard was an extra 4 Gigs extra off my HD. The software updates that I needed after that (for 10.5.7, and various other updates) was going to take another 4+ gigs. Is this all common problems, or did I do something wrong? Any light you guys can shine on this would be great. P.S. I have a Macbook Pro.
