Hi Adanna,

I assume you have already verified that gdb is behaving properly for you 
on macOS? If not, you should do that first as my understanding is that gdb 
itself no longer works well (if at all) on macOS (although this may be 
dependent upon your compiler, e.g., you could probably expect it to be 
more compatible with gcc than with the Apple compiler).

I am not aware of any GUI substitute for ddd that can work with gdb on 
macOS or anywhere else for that matter. I am still using ddd effectively 
on my Linux platforms.

I have not used it successfully for years, if you can figure out how please let me know! (I figured out how to use Xcode's debugger in standalone mode as a substitute for ddd.)
