Hey I also have this issue. Running Osx 10.11.6 on a late 2013 Macbook Pro. But blacklionisd's solution worked for me! Thanks friend!!

I just bought white march i + ii a few days ago - and now they're unplayable. Any word from Obsidian on what their plan is to sort this out?

Yeah I have a similar issue, playing on a MacBook Pro 2013 Intel Iris Pro. Pink everywhere as of today! https://imgur.com/a/babcX I tried uninstalling and reinstalling the complete game (ie including white march 1+2) without effect, although the base game works if I don't install white march I and II.
