subprocess.check_output возвращает байты, re.search принимает строки, все логично.

Python

>>> import subprocess
>>> import re
>>>
>>> ifc = subprocess.check_output(["ifconfig", "en0"])
>>>
>>>
>>> re.search(r'(..:){5}..', ifc)
Traceback (most recent call last):

    return _compile(pattern, flags).search(string)
TypeError: cannot use a string pattern on a bytes-like object
>>>
>>>
>>> re.search(r'(..:){5}..', ifc.decode())
<re.Match object; span=(157, 174), match='14:7d:da:73:bb:34'>
