So I'm new to Mac and just trying to figure out how to do basic things like I'm used to from Windows. I found that double-tapping the title bar of windows typically only maximizes in one direction (almost always vertically). I've also tried Option+Click on the green button and Shift+Double click on the title bar. Even on Finder, it only resizes, but never maximizes. Is there a simple solution to this that I'm missing?
Thanks.
[Update]: For those wondering, I ended up finding no native solution for this, but the Spectacle app worked well to solve this issue. Thanks for all the responses.
