I’m trying to install Mypaint on a new MacBook Pro and after installing Xcode, Macports, and XQuartz, I get the following problem initiating MyPaint:

I managed to compile it on Sierra a while ago, with both Homebrew and Macports. Please see my notes here:

It’s not easy and I’m not sure if things have changed with High Sierra. Also, I wasn’t able to get pressure working, but I was using a virtual machine so maybe that’s part of it. Please let us know if you have any success!

Many thanks for these notes! I’ll work on it and send a summary if/when I get things straight.
