I'll second that -- just use the command line tools.  I do all my SIMH work on Mac OS (Yosemite).  It's Unix, pretty similar to the BSD family.  Not quite so much like Linux.  Makefiles and all that work fine.

Be aware that recent Xcode releases use the Clang (LLVM) compiler, even though it calls itself gcc.  It's pretty compatible with the real thing, and if you want to, you can install the real gcc.

For debugging I use gdb, with -O0 because clang is not useable with gcc with -O1 or higher (unlike real gcc).  I tried lldb, gave up on that.
