Whether using Safari or Firefox practically all web sites take forever to load
e.g. both the address bar and the tab will show the page but the gear wheel keeps spinning and it can take a minute or two for it to fully load. The computer also hangs up periodically and on occasion Safari will spontaneously quit.
I am using the original operating system that came with the computer OS X version 10.6.8
I also have a 3 year old IPad which connects via a Mac router (airport express) and that connects and works much more quickly. Would an upgrade to the Yosemite be of any help ?
