Broken with pyobjc 7.0

[ErikBjare]

See this issue: ActivityWatch/aw-watcher-input#2

Looks like CFMachPortCreateRunLoopSource has moved from Quartz to CoreFoundation.

[Ignore this whole comment. The 3.7.9 results in particular are from the virtualenv I was having trouble with in a previous issue.]

Here are the results of my running "import Quartz" in Python 3.7.9 and Python 3.9.1

In 3.9.1 Quartz.CFMachPortCreateRunLoopSource does exist, so probably OK to close this issue depending on what Python versions you intend to support.

I was using 3.7 in order to build ActivityWatch. I will now try 3.9.1 for building aw-watcher-input.

This did not resolve the issue.

I've rolled jedi back a version with pip install jedi==0.17.2 and this does seem to have helped somewhat. aw-watcher-input now logs mouse moves. Got this idea from ipython/ipython#12740 after seeing errors with tab completion in my latest installation of ipython.

Still gives the AttributeError: CFMachPortCreateRunLoopSource error on startup though.

Update: the behavior seems intermittent, and the jedi rollback was likely unrelated.

As noted in the readme, this library is unmaintained, and it would be better to use Pynput instead. You are of course welcome to maintain your own forks or take over development if you're really interested.
