How to tile windows on a Mac
This is how each method works:
Tile by drag
Drag an application window to the edge of your display — it can be the top, left, or right, or even any corner — and a highlighted area should appear in the region in which your window sits. Release the window and it will snap into position once your pointer reaches the edge of the screen; don’t be impatient as the Mac responds to the position of your cursor to decide where the window is placed.
Use the Option key
A faster way to get your windows in order is to press the Option key while dragging the window toward the top, left, or right edge of the screen and release that window once it is in the highlighted area. It will snap into place, though if you intend on placing four windows you must move the cursor all the way to the corner.
