# pyobjc-framework-InstallerPlugins — Wrappers for the framework InstallerPlugins on macOS

License: permissive · Maintenance: active · Downloads: 656.5K/mo

## What it is and what it does

This package is a PyObjC wrapper that bridges Python to Apple's InstallerPlugins framework on macOS. It allows you to write Python code that interacts with the native macOS installer framework, enabling development of plugins that extend the functionality of .pkg and .mpkg installer packages. The wrapper translates between Python and Objective-C, handling the low-level bridge so you can work in Python rather than Objective-C directly.

The package itself does not include documentation—you rely on Apple's official InstallerPlugins framework documentation and PyObjC's general documentation for how to use the framework and translate between Python and Objective-C idioms. It is a thin binding layer, not a high-level abstraction, so you need to understand both the underlying framework and PyObjC's translation patterns to use it effectively.

Use it for:

- Develop custom installer plugins in Python that add new capabilities to macOS .pkg installers.
- Automate or script installer behavior by programmatically interacting with the InstallerPlugins framework.
- Extend .mpkg (meta-package) installers with Python-based plugin logic on macOS systems.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides Python bindings to macOS's InstallerPlugins framework, enabling you to develop plugins that extend .pkg and .mpkg installer functionality on macOS.

Yes, if you are developing macOS installer plugins and prefer to work in Python rather than Objective-C. The package is actively maintained, has no known vulnerabilities, and carries a permissive MIT license. Install friction is low. However, this is a niche tool—only useful if you specifically need to build InstallerPlugins framework extensions on macOS.

## Install

pip install pyobjc-framework-installerplugins
uv add pyobjc-framework-installerplugins
poetry add pyobjc-framework-installerplugins

## Installing pyobjc-framework-InstallerPlugins

Before you install: Low friction install with a pure-Python wheel. Actively maintained as of 2026-08-14 with recent releases. Depends on pyobjc-core and pyobjc-framework-Cocoa, both part of the same PyObjC ecosystem.

License in practice: MIT license permits commercial and private use with minimal restrictions—you may use, modify, and distribute this package freely as long as you include the license notice.

Quickstart:

pip install pyobjc-framework-installerplugins

import InstallerPlugins
# Access InstallerPlugins framework classes and methods

Requires macOS and Python 3.10 or later; only functional on macOS systems with the native InstallerPlugins framework available.

Verify before relying:

- Whether the package includes example code or sample installer plugins beyond the framework bindings themselves.
- What specific InstallerPlugins framework classes and methods are exposed by the wrapper.
