Well, thanks for the non-insightful post, Pr1mo! j/k
Think is, there's things that macs does better than PCs. Bad thing is, you need a very expensive mac, and very expensive programs for it. I mean, there's a damn good reason why (virtually) everyone who's working professionally with graphic design use macs, and they do handle movie editing better. Though, they handle a good deal of other things worse, and that's why I stick to my PC no matter what. But saying that there's no nichй that the mac doesn't handle better is straight up lies.
Oh, and yes, to take 360 degrees screenshots, you'd need Quicktime. And that is mac country, so it won't happen in SWG (they won't pay the humongeous amount of money it would cost to include a registered version with every copy of SWG).
For recording demos, you need different programs depending on what game it is. Thing is, the program either registers everything that happens on the server, because that's the only way you can make a demo where you can check everything, or it registers only what you see, and that is worthless. And if you made a program that registered everything that happened on the server (which is very very difficult, and illegal, since it would require you to hack SOEs servers), the disadvantage would be that the movies would be huge.
So no, the chances of recording battles are very, very, very, very, very, very, very, very, very slim.
EDIT:
Here's how to make demos in Quake 3 Arena (
