1Automatically Resize Windows
Let’s start with the simple stuff.
First of all, macOS offers a little extra help when it comes to perfectly aligning your windows.
This is to help you snap the edges together to maximize your screen real estate.
To enter Full Screen, just opt for green button in the top-left corner of an app window.
If the button is grayed out, it means that app doesn’t support it, which happens occasionally.
Start by opening a normal window for each app you want to use in Split Screen mode.
Just move your mouse to the top or bottom of the screen to make them reappear.
But it’s another option that’s worth experimenting with as there are some cool aspects.
Then you could switch to another stage with your emails and instant messaging apps for some communication.
bring up the bottom-right dropdown menu and select “Quick Note” from the options.
