On a serious note: if you need automatic window tiling in OS X, you should check out Amethyst [0] (available via homebrew cask). I mention this everywhere I can because I spent a lot of time searching for and testing various window management software for OS X myself, and Amethyst is only easy, fully functional alternative I've found that works out of the box.

What about BetterTouchTool? I don't like window tiling in general, so I only use it for the gestures, but from what I've seen the tiling features seem pretty complete.

I haven't really used it, but from what I can tell it seems to serve the same purpose as Moom/SizeUp/Divvy/Spectacle/Slate/ShiftIt with regard to windows (i.e. moving and resizing).

Amethyst (an automatic or dynamic tiling window manager), on the other hand, automatically arranges windows according to predefined tiled layouts (like XMonad, Awesome, etc.).

What I'm trying to explain might become more clear if you watch [0], wherein you can see that all windows on the (virtual) desktop are adjusted in size and position in response to opening or closing other windows.

I use it also. It's a fantastic way to keep everything visible and organized. There's a few quirks and it can be annoying sometimes to have the whole desktop rearranged when opening a new window, but the quirks are overshadowed by its usefulness.

Or get Hammerspoon[0] and roll your own window manager with Lua.

Sorry, amethyst is nowhere near real tiling window managers. Hopefully with this we'll see real tiling window managers.

In what way? What functionality do you think that Amethyst is missing?

As for "Split View", it looks more like a simple two-window extension of the existing full screen functionality to me.

I haven't had a chance to try reverse engineering the APIs, but on the surface nothing has changed with the accessibility framework, which means we're not going to get much progress towards better window management.

Unfortunately seems heavily mouse based. I'll stick with Spectacle myself.

Spectacle was about the only way to make my multi-monitor OSX experience work. It was maddening. Nice to see them catch up to at least acknowledge that everyone doesn't like the messy overlapping windows look.

I've been using slate for a while now. Highly recommended.

The original jigish/slate project hasn't been updated since Feb 2013. The mattr-/slate fork has been solid for me since 10.9+ and is maintained regularly:

I love slate and have used it for years... it's no longer actively maintained and has a lot of performance bugs. I've started using other window managers like https://github.com/ianyh/Amethyst

I use Divvy on Mac and Windows. It's fantastic.
