Make coretest.py concept script for Mac

[qlixed]

Make a coretest.py compatible for Mac.
If this is not possible then make a similar concept script.

Apparently macOS support cores in a linux-like fashion.
Need to enable the cores as system wide in version prior to 10.4 apparently:

All the cores goes to /cores path, and have the pattern cores.PID.

A native gdb preinstalled alternative exists maybe?
