This isn't the member introductions section. Give your topic a proper title and not "hey guys".

 

Do you get this Segmentation fault: 11 only when attaching MCT or every other process?

World At Arms has Anti-Debugging Protection (ptrace)

 

You need to disable ptrace in order to debug the process. Disable ptrace by doing this:

 

Open Terminal and type in:

gdb /User/Containers/Bundle/Application/xxxxxx-xxxx-xxx-xxx-xxxxxx/MCT.app/MCT

Then:

break ptrace

Then:

run

Terminal will show you the Offset. Go to the offset in IDA and NOP ptrace and then attach MCT again normally.

Oh you were hacking World At Arms...

Can't believe that an online multiplayer game could be hacked so easily
