TBB sandbox 7.0a3 does not open

When I bootstrap tor in sandbox mode and then ./start-browser-with-sandbox I get multiple errors and tor browser bundle opens in a very small window and does not have any of the Add-ons installed, and does not work. I'm running macOS 10.12.4 (16E195) tor browser bundle 7.0a3 Here are the errors I get in terminal
