Ollydbg equivalent for Mac OS X [closed]

Question

is there any good equivalent debugger for Mac OS X?

Something that allows patching and saving of the assembly as well (with graphic interface?)

Thanks!

Answer 1

GDB is the gold standard for debugging on *nix. GDB has all of the debugging features you would expect in a modern debugger. For example, reverse debugging is the best feature to have if you are modifying the binary in memory, when you make a mistake just step back and try again. DDD is a popular front end, but seriously you should learn GDB's CLI. It has bit of a learning curve, but once you learn it you'll never go back. Its a lot faster.

Saving a modified binary isn't that great of a feature. Just open the binary with a hex editor like Hex Fiend and modify it directly, not a big deal.

I'm not a OSX person, but you might find IDA useful, however, you will probably need to pay for the linux/osx versions, as there is only a free version for windows.
