Hi, I downloaded the latest version specified on the site for Mac (I have OS X El Capitán 10.11.6) and Krita barely opens.
When inside I was checking the tools alright but when created a new file to test the brushes it completely crashed, places where I drew became transparent , brush disappeared, program closed suddenly. I thought it was because of my cintiq so I tried my other tablet and same thing. Tryed it even with the mouse but could't get it work well.

So sad because I really wanted to try this program.
