Good question :-). I thought CGEventTapCreate and related APIs could be used
for this, but now that I’ve reread the documentation I no longer think so.
MASShortCut still uses the Carbon APIs in its implementation, which seems to
confirm that there is no good modern alternative for the RegisterEventHotKey
API.

I have created an experimental binding to MASShortcut on my bitbucket account:
https://bitbucket.org/ronaldoussoren/pyobjc-masshortcut
<https://bitbucket.org/ronaldoussoren/pyobjc-masshortcut>. This library can be
installed using “pip install pyobjc-MASShortcut==1.0a0” (and has a wheel if you
use a 64-bit installation of Python 3.7)
This “works” in the sense that I ran my unit tests with Python 3.6 (64-bit),
but I have done no testing beyond that.
Creating the bindings was fairly easy, but harder than it should be because the
tooling I use to create bindings is primarily created for Apple’s system
frameworks and has some issues with 3th-party frameworks. I do want to improve
the tooling for this, but don’t know when I’ll get around to actually doing
this.
