How Do i get a Converter?

For the add ons.

Where do i get a converter for the evnova add on files?
Cus i got a Mac and Most f them are for PC.

Heh, no, almost all of them are for mac. But anyway, I'd suggest browsing the utilities section of the addons pages.

Eat some carrots. Maybe it'll help you see the pinned topic at the top of the forum.
