Lately, all of our laptops and mac minis with Snow Leopard 10.6.8 have been freezing while viewing things on the internet, or will not go to sites, e.g. the blue line that usually indicates a web page is loading just freezes halfway and locks up the computer. We also have shared printers connected via airport, every so often we can't print anything unless we completely restart the computers and even then sometimes it won't print. I have read discussions on all kinds of forums but no real answers. Is this just Apple's way of getting us to upgrade to their crappy Lion?
