Hard Drive Issues?! Can't download updates or install new apps
My issue is this: I can download but not install/launch new applications. I've tried updating safari but the .pkg file won't open. I've tried a software update from the apple menu but it says there's a network error 1011 yet i'm online?! I tried a standalone download of a combo update but it stopped halfway through...I CANNOT DO ANYTHING!!!
The machine is working fine, no strange noises, I can work everything on the mac as it should (internet, itunes, calendar etc all fine).
Why can't I update my software and why can't I launch my new applications/programs that I've downloaded?
I downloaded a combo update to a usb from another machine and it started the install procedure but when it came to selecting the destination, my hard drive was not selectable and said 'You cannot install mac os x update combined to this volume. ERROR_INSTALL. Went to partition the hard drive as recommended, but I can't as it's the startup volume...HELP PLEASE!!
