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/MCTThen:break ptraceThen:runTerminal will show you the Offset. Go to the offset in IDA and NOP ptrace and then attach MCT again normally.
