(MPF will work with Python 3.8 - 3.11.) 1. The easiest way to install MPF on a Mac is to use the [Homebrew package manager](https://brew.sh). Open your command terminal and paste and run this command: - `/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"` + ``` { .bash .copy} + + /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" + + ``` This will also install the Xcode command line tools if you don't have them. This process might take some time, so be patient. 2. Use Homebrew (or 'brew') to install the Python and the multimedia libraries MPF and MPF-MC need: - `brew install python@3.11 SDL2_mixer SDL2_image gstreamer` + ``` { .bash .copy} + + brew install python@3.11 SDL2_mixer SDL2_image gstreamer + + ``` 3. Install the various MPF packages. For example, to install MPF, MPF-MC, and MPF Monitor: - `pip3 install mpf mpf-mc mpf-monitor --pre` + ``` { .bash .copy} + + pip3 install mpf mpf-mc mpf-monitor --pre + + ``` Note that the `--pre` flag tells pip to install "pre-release" versions, which is how you get the 0.57 versions of these packages. If you omit that flag, you'll get 0.56 versions. -4. You're ready to go!

This can be a problem because MPF -requires Python 3.7, 3.8, or 3.9 (3.9 only on M1/M2 Macs), but the -homebrew python could be version 3.10 which won't work with MPF.
