Was really looking forward to Yosemite for the Dark mode (I hated having a white bar at the top of my second display (in Mavericks) - So distracting! Im also not liking to Translucency - So like many, I've reduced in in Accessibility. Bit disappointing, but there seem to be little bugs all over; Anyone else picked up on these? I know its not the biggest problem in the world, just an annoyance really. Apple pride themselves on being beautiful . . . Seems like they get more sloppy with each release!
