Herewith my conversation on the facebookpage concerning a start up problem of affinity: me: now I'm having an awkward problem: affinity won't start up. I get the logo and then a black screen and the colored wheel that keeps turning. I've already restarted the Mac but it doesn't help. I recently installed macOS high Sierra. could that be the reason? answer:Hi Pieter, it should be working fine. Please could you try opening the app with the CTRL key held down then click Select All and then Clear to see if that resolves your issue? me: I thought I solved it... with your advice I succeed in opening the software with appearance of the start up screen but then the fireball appears again and it is there to stay and the program doesn't run... answer:Hi Pieter, please could you make a post about this on our Support Forum found below so a member of our Development team can look into this further for you? https://forum.affinity.serif.com/index.php?/forum/38-bugs-in-affinity-designer-affinity-photo/
