How do you run a .BIN file?
 

I've searched the web for the answer and have tried this chmod a+x *.bin and .BIN but nothing has seemed to work. When I try to run it it says bash: ./macmsgs.bin: cannot execute binary file
How do I get it to run properly?

try:

sh ./filename.bin

or

sh filename.bin

The .bin extension doesn't always indicate a Linux binary executable. In your case, it looks like you've got a MacIntosh file compressed in MacBinary format.

:p

edit: nevermind. my bad.
