Is os.mknod() a privileged call on Mac? It always fails with operation not permitted?

In [1]: import os

In [2]: os.mknod("/tmp/test123")

Unfortunately mknod requires escalated privileges. If you don't need mknod specifically though, just create the file with open, which doesn't require escalation:

open('/tmp/test123', 'w').close()

If you want to write to the file in addition to creating it:

with open('/tmp/test123', 'w') as file:
    file.write('hello world')

Using with as above will automatically close the file for you.
