MacOS – Split view with green button does not work in macOS Sierra

macosmission-controlsplit view

When I try to use split view feature in macOS Sierra, I can not use the green button any more. Every help page found by google suggests I should click and hold the green button to activate split screen for the current window. The window would shrink and I could move it left or right and then choose an other open window to place it on the other side. This does not work with my MacBook on macOS Sierra.

I can use split view via mission control for windows already opened in full screen, thats's fine. But sometimes I might prefer to activate it directly from the current window without putting it to full screen first.

Edit: I have no 3rd party tools for windows management in use. I tried with Safari an Maps, both 1st party tools that do support the feature, as far as I know.

Go to System Settings -> Mission Control activate the checkbox displays have separate spaces.

Log out and In and check if it works.

You can use one of the actions of the "AXFullScreenButton":

"AXZoomWindow" action to maximize.
"AXPress" action to full screen.

Use the perform action command, like this.

tell application "System Events"
    perform action "AXZoomWindow" of (first button whose subrole is "AXFullScreenButton") of (first window whose subrole is "AXStandardWindow") of (first process whose frontmost is true)
end tell

MacOS – Yosemite Mission Control does not show desktop bar or add button

I was just being an idiot. As it turns out, I had the keyboard shortcut from my MBP for "Mission Control" assigned to "Application windows" on the Mini, and because Application windows looks a lot like Mission Control, I was confusing them. After putting in the correct keyboard shortcut for Mission Control, now I am able to get my desktop spaces created correctly.
