Can this be compiled once instead of re-compiling on every function call?

We should follow the indentation style for other docstrings.

No need to enumerate if you're not using the index.

You can also use splitlines().

You are mutating data at the caller here. You could just encode it ad the for loop itself.

This can simply be:
return '\n'.join(output)
| data = data.decode('utf-8') | ||
|
|
||
| for i, line in enumerate(data.split('\n')): | ||
| chunk = line |

Temporary assignment not necessary.

Could this all be reduced to just
if any([ord(byte) not in range(32, 128) for byte in middle]):

It might be worth investigating doing all of this in an XML library. This function is assuming that ioreg will always return data in a specific format.

Python 3.6.0's plistlib has removed readPlistFromString in favor of loads. There isn't a backwards compatible upgrade path, so feature detection was necessary instead.
This patch fixes Python 3.6.0 by trying plistlib.loads when AttributeError is thrown from attempting to call plistlib.readPlistFromString.
Additionally, dict.iteritems() is deprecated in favor of dict.items() in Python 3. This also works in Python 2.7.
Tested both Python 2.7 (standard install) and Python 3.6.0 (Anaconda) on macOS Sierra 10.12.4 (16E195).
