Similarly, it'd also be nice if they warned users that disabling the setting will also disable Split View.Īnnoyingly, changing the setting requires logging out and back in again, so it's a bit disruptive.

'To use Split View, please check the 'Displays have separate Spaces' box in the Mission Control pane of System Preferences.' Apple could also provide a button to take a user directly to the right spot to change the setting. So why not display a simple dialog when a user selects one of the Split View options while the setting is disabled? This is a case where it seems like it'd be incredibly simple for Apple to provide a bit of feedback to the user–Apple is clearly aware of the need to have that setting enabled, and can easily check the setting. Secondly, the above note only appears on the Catalina Split View page, but it also applies to Mojave-again regardless of the number of attached displays. So this setting is required to be enabled to use Split View at all, regardless of the number of displays. As soon as I toggled the setting back on, Split View worked perfectly. But the above movie was recorded on my single-screen MacBook Pro. The first is related to the bit of emphasized text: Apple's note makes it seem that you only need to have this setting enabled if you're trying to use Split View on other displays. To use apps in Split View on other displays, make sure the “Displays have separate Spaces” checkbox is selected in Mission Control preferences.

I've added a bit of emphasis to one section of the quote… Most users will never experience the above problem, as it only occurs if you've changed a seemingly-unrelated system setting: Unchecking the 'Displays have separate Spaces' checkbox in the Mission Control System Preferences panel.Īpple notes this requirement at the very bottom of the Catalina (but not Mojave) Split View page. Sorry, but your browser does not support the tag here's a link to the movie.Īs you can see, the full screen menu item works, but the two Split View entries do nothing at all-no error message, but nothing happens other than the menu vanishes.
