Ok, I need so help with this one. The download filename for the Picc Lite OS-X compiler is the same as its Windows counterpart. The Mac doesn't know what to do with self-extracting exe files. If I'm somehow overlooking something, would someone please point me in the right direction? Hi-Tech doesn't have anything relating to a Mac problem in their forums. Thanks!
