On your screen’s top left corner, navigate to Apple menu System PreferencesMission Control. Ensure the box besides Displays have separate Spaces is checked. All Mac OS beginning with OS X El Capitan supports the Split View mode. However, Mac OS Catalina (the most recent OS), has a different action sequence for launching the mode. TIFF Splitter for Mac supports splitting a single TIFF document into multiple TIFF documents or other image formats within a few clicks. It is a simple and powerful program, with a user-friendly interface to split TIFF documents in seconds. Users can split TIFF documents into different image formats, such as jpeg, png, tiff, gif, and BMP. For now, XSplit Broadcaster is only compatible with Windows 7 OS and higher. Our team is currently developing support for Mac OS, and it will be available this year (2021). As a workaround, you can install Boot Camp OS to run Windows applications on your Mac OS device. Apple has a guide where you can learn more about Boot Camp OS here. The split-screen view in macOS is a simple and distinguished solution to your floating windows problem. Split view neatly positions two windows to fill your entire screen. Whether you are trying to.

macOS has had (since 10.14) a built-in Split View mode that lets you use your full screen to display two apps side by side, each in a quasi 'full screen' mode. Personally, I never use this feature—why limit yourself to just two windows?—but I know many people do.

In macOS Catalina, you activate Split View via a green button hover, which then shows this pop-up menu:

The activation method is somewhat different in 10.14, but the end result is the same—a window taking up half your display. Except when it doesn't…

As 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.

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.

Apple notes this requirement at the very bottom of the Catalina (but not Mojave) Split View page. I've added a bit of emphasis to one section of the quote…

To use apps in Split View on other displays, make sure the “Displays have separate Spaces” checkbox is selected in Mission Control preferences.

There are two problems with this. 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. But the above movie was recorded on my single-screen MacBook Pro. As soon as I toggled the setting back on, Split View worked perfectly. So this setting is required to be enabled to use Split View at all, regardless of the number of displays.

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.

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. So why not display a simple dialog when a user selects one of the Split View options while the setting is disabled?

'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.

Similarly, it'd also be nice if they warned users that disabling the setting will also disable Split View.

Annoyingly, changing the setting requires logging out and back in again, so it's a bit disruptive. But if you want to use Split View, and you've changed this setting in the past, you'll have to be disrupted.

Enter Split View

If you're using macOS Catalina or later:

1. Hover your pointer over the full-screen button in the upper-left corner of a window. Or click and hold the button.
   
2. Choose ”Tile Window to Left of Screen” or ”Tile Window to Right of Screen” from the menu. The window then fills that side of the screen.
   
3. Then click a window on the other side of the screen to begin using both windows side by side.

If you're using macOS Mojave, High Sierra, Sierra, or El Capitan:

1. Click and hold the full-screen button in the upper-left corner of a window.
2. As you hold the button, the window shrinks and you can drag it to the left or right side of the screen.
3. Release the button, then click a window on the other side of the screen to begin using both windows side by side.

If Split View doesn't work, choose Apple menu  > System Preferences, click Mission Control, and make sure that “Displays have separate Spaces” is selected.

Work in Split View

In Split View, you can use both apps side by side, without the distraction of other apps.

• Choose a window to work in by clicking anywhere in that window.
• Show the menu bar by moving the pointer to the top of the screen.
• Swap window positions by dragging a window to the other side.
• Adjust window width by dragging the vertical line between the windows.
• Switch to other apps or your desktop with Mission Control, or use a Multi-Touch gesture such as swiping left or right with four fingers on your trackpad.

Exit Split View

1. Move the pointer to the top of the screen to reveal the window buttons.
2. Click the full-screen button in either window. That window exits Split View.
3. The other window switches to full-screen view. You can switch to the full-screen window with Mission Control, or use a Multi-Touch gesture such as swiping left or right with four fingers on your trackpad.
