Update to any watching this issue: We have the program up and running well. In fact it will be the best version on Mac ever. We are still having issues signing and packaging the distribution. Hoping we can get an alpha up in the next few days.
Also white screen. I contacted MatterHackers and got the response that they are flooded with support request and will answer personally in 2-3 days.
