Fixing SageMath on macOS

This small module is to help folks install and use SnapPy inside SageMath. It has been superseded by Sage_macOS which is a version of Sage with all these fixes and more built in.

This module does two things:

1. Provide SSL support via openssl so that sage -pip install snappy works.
2. Install a recent version of Tk so that the SnapPy's graphics work in Sage.

Depending on the version of Sage that you have installed, download one of fix_mac_sage8.tar.gz, fix_mac_sage9_0_and_9_1.tar.gz or fix_sage_9_2.tgz from:

http://github.com/3-manifolds/fix_mac_sage/releases/latest/

(Sage 9.2 requires fix_sage_9_2.tgz because it uses Python 3.8 instead of Python 3.7. Earlier versions of Sage 9 can use fix_mac_sage9_0_and_9_1.tar.gz.) Assuming you are using Sage 9.2 installed in /Applications/SageMath and downloaded this package into ~/Downloads, do:

cd ~/Downloads
sudo xattr -d com.apple.quarantine fix_mac_sage9_2.tgz
tar xf fix_mac_sage9_2.tgz
/Applications/SageMath/sage -python -m fix_mac_sage9_2.fix
