Obviously I have an older Mac mini that works great for graphics, etc. However, almost overnight, I am unable to view anything that requires Shockwave, Flash and receive an notice to update. An old story, but when I try to update, it calls for 10.4, and doesn't work. I hope I don't have to replace my computer at this time ($) but I need a solution. Can I upgrade my operating system to make it work or am I hopeless?
