API notes: Accounts framework
An introduction to PyObjC describes the general method for translating Objective-C calls into Python calls, including the handling of pass-by-reference arguments and buffers.
This document describes where the PyObjC bindings for this framework are different from the general rule, such as mentioning APIs that are not supported or where the interface is different than expected.
The framework is documented on Apple’s developer website
The entire “Accounts” framework on MacOSX 10.8 (or later) is available from Python.
The Accounts framework is only available in 64-bit applications.
