Newer MacBook can't run Mu locally

[Gigi1111]

What were you trying to do?

Run Mu locally.

What steps did you take to trigger the issue?

1. git clone the Mu repo
2. pip install -e ".[dev]" to install dependencies
3. attempt the mu-editor command to run mu locally to check the changes

What did you expect to happen?

Running Mu locally.

What actually happened?

Mu not running locally, and seeing ModuleNotFoundError: No module named 'PyQt5' in the terminal.

Operating System Version

macOS BigSur 11.6

Mu Version

v1.2.0

Other Info

It seems that the PyQt package v.5 that Mu (v1.2.0) is using for UI isn't compatible with the system architecture of newer Mac computers. Instead of the x86_64 architecture used on Intel-based Mac machines, newer Macs like the ones with M1 chip use ARMv8.5 architecture. Consequently, applications using PyQt can't be run until the package is compiled be ARM-compatible.

Fortunately, the PyQt team developed universal binaries for both Intel and Apple Silicon hardware from version 6 of the package. At the moment, Tiego has created a workaround in the setup.py file on branch pyqt6 for Mac Silicon users to run Mu locally.

However, it hasn't been documented for contributors, so please add it to the setup section to make the contributing process smoother and easier.
