Fails to check PID in Mac OS

[die4live]

[valensc]

pylane just support Linux and BSD, for mac os, things should be done:

1. avoid to use /proc to check process
2. handle gdb codesigned issue in mac os

we will working on them later~

I've avoid this issue by modifying the ensure_pid in core/injector.py

121     def ensure_pid(self, pid):
122         """"""
123         sts, pids = subprocess.getstatusoutput("ps | awk 'NR>1{print $1}'")
124         pids = [int(pid) for pid in pids.split('\n')]
125         # if not pid or not os.path.exits('/proc/%s' % pid):
126         if not pid or not pid in pids:
127             raise RequirementsInvalid('Process %s not exist.' % pid)
128         self.pid = pid

However, when run the example presented in Usage with pylane shell <PID>, the following error occurred.

@Lincoln12w does your process output anything or hang up after injection?

you can try gdb directly on your process, just attach and detach. in my case the process just hang up after attach and don't resume after detach.

I'm still looking into it.
