I'm brand new to the Mac game and for a bit there I thought this computer was the best thing since sliced bread. Now, I'm running into problems opening files from school. I was unable to open zip files (swf file, said that I do not have the applications to open file nor does it give any idea of which app that would be) and I was also unable to open a bunch of wmv. (prompt says that quicktime does not recognize the format). Not sure what to do from here. Tried a different browser, no luck. Also tried Perian for QuickTime, no luck. Any idea?
