cannot connect to the app store to update from 10.8.5 to 10.9
when trying to update from OS X 10.8.5, imac says cannot connect to the app store. but i have internet connection. why is this?
not sure if the issue is connect to my itunes, but that too is giving me issues. when i link my iphone to my imac, i recieve this:
itunes can't verify the indentity of the server play.itunes.apple.com", asking me to cancel or continue. then another window appears, "itunes can't verify the identity of the server"p46-buy.itunes.apple.com". it keep going on...
I purchased the Adobe Creative Cloud but can't do anything because i need to update to 10.9.
can someone help?
mac pro, Mac OS X (10.5)
