Yesterday I updated my computer (2 month old MacBook with Lion) with the new Lion Recovery Update 1.0, Mac OS X Update 10.7.2 and iTunes 10.5. Within these updates was Safari 5.1.1. Since the upgrade I have not been able use safari and get onto the Internet. No error messages come up, it's just a blank page. I know it is not something wrong with the network itself because I have tried other people's computers that have all worked. I've even tried using other Internet cables that I know work and nothing has happened. Wifi won't work either. Could it have something to do with the new iCloud which won't let me log on either?? Please help! I'm a Uni student who desperately needs the internet! I'm also somewhat technologically illiterate, so use small words please! Hope someone can help, thanks in advance!
