@pudquick just wondering if you've revisited this given some deprecations that are going to happen in PyObjC 9:

/usr/local/bin/redlands/mount_shares.py:24: DeprecationWarning: This function will be removed in PyObjC 9, switch to the modern metadata system
  NetFS_bundle = objc.initFrameworkWrapper('NetFS',  frameworkIdentifier=None, frameworkPath=objc.pathForFramework('NetFS.framework'), 1globals=NetFS, scan_classes=False)

Thanks @pudquick for the chat over Slack about the changes that will be upcoming to PyObjC 9.

For anyone else using this, you should be able to comment out these lines and simply replace it all with import NetFS and have it work...
(tested against PyObjC v7.3).
