Macs have supported simple-to-use multi-monitor displays since an era when they were unknown on PCs. Like, back when Macs were still predominantly black and white machines, when people wore suits with huge shoulder pads and big hair was all the rage. (I once had an SE/30 equipped with a video card that powered an external display.) But when OS X Lion came out in 2011, Apple backslid when they introduced full-screen apps, which would cause one monitor to display a pattern while the other one held the app. And using Spaces since Lion - especially with multiple monitors - was an exercise in teeth-grinding frustration. Apple's changing that in Mavericks, making multiple displays finally work the way they're supposed to. And it looks like a lot of you are looking forward to it - based on our recent poll, more than half of respondents are enthusiastic about these improvements.
