The Permission denied could mean anything from the target being read-only, missing read/write access (user privileges), folder/file does not exist, or a miss-parsed error.  None of these are very likely.

My guess is that your file was not saved with a proper file extension (ex: *.c or *.cpp).  However,

often means that you do not have a compiler set up (note that Code::Blocks is an IDE, not a compiler).
See installing a compiler and troubleshooting.

By the way, when posting log output, could you please use code tags?

Note: I have no experience on a Mac, so there could be something obvious I have misunderstood/not noticed.
