[Tutorial Videos]

Hello again,

I'm trying to watch the tutorial videos and they don't work.  It's all just a black screen.  I'm on a Mac.  Do they not work on a Mac?  Just trying to learn how everything works. 

[Where is the pixel persona?]

Hey guys,

I'm testing out the trial version of Affinity and I've uploaded some artwork that I want to create a transparent background for.  So far, all the tutorials I've found say that I need to be sure to pick the pixel persona, but in my version of Affinity there isn't one?  Am I missing something or is there another way to create a transparent background?   HELP!
