My only problem with both designs in your images is the colors. It’s a pretty standard part of UI design (in real life and on computers) that “red means cancel” and “green means continue.” Apple using blue is no big deal and I’m 90% sure they just use a user chosen “highlight color.” (Maybe Gnome as well?) But cancel or delete or similar things should probably be red or another color that signals “Stop.”
I’ve always thought Bootstrap, the web design library, has a good set of base colors. Red means danger. Light blue means info. Green means yes or success. Yellow means warning. Other buttons are a darker blue — basically the highlight color. (Not saying they chose the best version of those colors. Just that the general idea is consistency and what users most naturally expect.)
