so a couple of days ago i did those mac updates that you get every once in a while for itunes, safari, etc, etc etc...... anyway - the updates finished and it said that there was an error in one of the updates and it was the safari one. then it told me to restart my computer and i did - i figured if the one didn't finish it would just make me do it again later - no big deal right? well - i was waay wrong. safari won't even open up anymore. neither will itunes. a few others like adium but thats not a big deal. without safari i didn't know what to do. first i tried to reinstall it from the disks that came with my computer but i don't want to have to erase everything and when i tried to just reinstall the applications it didn't really do anything. so then i went and downloaded firefox from another computer and put it on my macbook and so now i have the internet again through that but it doesn't fix my other problems. i don't really care if i have to switch from safari to firefox but the other issue of itunes not working is a problem. i don't know if its a safari problem leaking into the other programs or if everything that was supposed to update got messed up. i tried downloading safari from apple's website but when i went to run/install it that wouldn't even work. i tried trashing safari thinking that maybe i needed to get rid of it entirely before downloading it fresh. it won't empty. i don't know. i feel really stupid that i can't figure this thing out. i'm usually not this clueless about my computer but i don't know what to do. if anyone can lend any advice or solutions i would really really appreciate it.
