Split Screen Not Working

Nothing should be lost if you have a full backup. The backup is just a precaution in case something goes wrong.

But no, you don't have to reinstall and you can carry on without Split View. It's just a convenience.

What size is the screen on your Mac?

Based on what I have read, it seems that 13" and smaller screens are limited in the feature due to the applications window width.

Spilt View is limited by the minimum width of an application's window when in standard view. If two app takes up more than the full width of the your display when you resize each application window to their minimum width, then they will not be able to be shared in Split View.

Here is a a couple of other ways to get into split screen. Note, not all apps work in split screen.

Do any of these get you into split view?

1. Put both of the two apps that you want on in split screen into full screen mode. Go to mission control and drag one full screen desktop of the other one and they will make one split screen space.

2. Have the 2 apps you want in standard view to use in split screen in any desktop space. Go to one of them and drag it up to the top of your display, past the menu bar and it will open mission control and drop the app window into an empty area on the desktops row at the top of mission control. The app makes its own full screen desktop space. Now go to the other app and do the same, dragging it up to the top of your screen into mission control and drop it on top of the first full screen app. They are then placed in spilt screen.

Actually that is not true. I have a 13" MacBook Air and a 12' MacBook and Split View works on both.

I didn't say that it doesn't work, but it may be limited be the screen size based on the apps being used.

iTunes is a good example, even on my 15" rMBP, there are apps that will not share the display when the display is set to default. Mail and Image Capture are examples.

Changing the resolution up one closer to More Space and those applications can be shared on the same screen.

Moving the resolution down on towards larger text, Safari cannot be shared with iTunes as it can in Default.

What happens if you change your resolution towards Larger Text, can you then share iTunes and Safari?

Or with your setting on default resolution can you share iTunes and Mail? In move your resolution towards More Space, can you then share these two apps?

What about Preview and Pages. if you drop your resolution towards Larger Text can you still share these apps?

Common dominator is the minimum width of an app dependant on the resolution.

All of these examples are effected on my 15" rMBP.

Users without retina displays I think are more effected by this limitation as they generally have a lower resolution than the rMB models.

I guess I am missing something…

13" MacBook Air Mid 2013

Safari and iTunes

Pages and Preview

Try starting in safe mode then normal mode…

OS X El Capitan: Start up in safe mode

You can try to reset the SMC

Reset the System Management Controller (SMC) on your Mac - Apple Support

If that doesn't work, I'm out of ideas short of reinstalling OSX 10.11.

Split View only works with apps that are split view enabled.

Displays Have Separate Spaces, checked, ok.

Are you in Full Screen Mode, going to split screen only works if you are in normal screen mode.

Just curious, is your display set to scaled mode? If so, can you try switching to Default for display?
