Great post... I used Fusion a long time because I had serious problems with the marketing strategy of Parallels. Fusion worked ok, until I experienced several problems with the Construct 2 UI.
Somehow my layouts did not update but stayed black, action items suddenly appear/disappear when hovering with the mouse over them...
Also testing the games in the Edge (or other browser) show a lot of lag. Last weekend I installed Parallels v11 (trial) and guess what... everything worked like a charm! Fast and no problems!
I do have to give Parallels the credits at this time
