When I try to install Electrum from Source for Mac I get the following error on the terminal:
Error: Could not import PyQt5 on Linux systems, you may try 'sudo apt-get install python3-pyqt5'
About the QR code, sorry about that, wasn't aware about the MacOS limited support for QR codes.
Ahh! It could be cause of PyQT5 dependencies missing. Could you try to install the following dependencies? Type the following in your macOS terminal:
brew install qt5 pyqt5 gettext
If that still doesn't work you can also try installing PyQT5 from pip:
python3 -m pip install PyQt5
Edit: To run brew you may have to install Homebrew:
https://github.com/mxcl/homebrewTo do that you can run the following:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Source of homebrew installation command:
https://brew.sh/Note: Not sure yet, how this does disable the next button though, cause it was enabled in previous instances of the wizard. But, hey lets try to install the dependencies to ensure they aren't missing, if any and retry.
