I recently did the update to OSX and since then my mac has gone horribly wrong and I'm hoping you can help me find the problem and fix it!! There are many many problems now and I'll list what's happening: iTunes - When I try and launch iTunes I get the error "The iTunes application could not be opened. An unknown error occurred (13014)" Mail - I get the following error when trying to retrieve messages - There may be a problem with the mail server or network. Verify the settings for account Gmail or try again. The server returned the error: The connection to host pop.gmail.com on port 995 failed. Appstore - I get "Cannot connect to the app store" Spotify - Doesn't work, when launching I get the error "keychain "login" cannot be found to store "nothctap" (that's my username). When I try and play a song I get an error "There was a problem storing temporary files on the hard disk" Safari - Randomly crashes and won't access my internet banking or any apple help sites. I get a blank browser with the following text - Safari cant open the page https://discussions.apple.com/thread...rt=0&tstart=0 because the server unexpectedly dropped the connection. This sometimes occurs when the server is busy. Wait for a few minutes, and then try again. I can't download anything at all, when I try and download something I get the following error - Safari could not download the file Name of file in here because there is not enough free disk space. When I go to my hard drive and click get info, it's telling me I've got 44GB of free space. Please can someone try and help me out. I didn't have time machine set up and I can't find my snow leopard disk anywhere so I'm stuck as to what I should do. I wanted to upgrade to Lion but I can't access the App Store to download it. Many thanks in advance P.S. It wouldn't even allow me to post this, I've had to use my iPhone. Could this be a virus???
