To return to the previous window size, Option-click the button again.If you want to double-click a window’s title bar to maximize it, make sure “Double-click a window’s title bar to” is set to Fill in Desktop & Dock settings.
  • Minimize a window: Click the yellow minimize button in the top-left corner of the window, or press Command-M.You can set an option in Desktop & Dock settings to have a window minimize when you double-click its title bar.

Most windows can be manually resized. Drag the window’s edge (top, bottom, or sides) or double-click an edge to expand that side of the window.

macOS High Sierra, or older

For macOS High Sierra or older, Apple offered only “Full-screen” mode in Safari. In these earlier OSes, it was not natively possible to “maximize” the browser window in regular screen mode in certain versions of macOS. Here are some resources that help with that.

Recommendation for Safari on High Sierra: Magnet App

Magnet is a Window Manager app for macOS, that has the added benefit of including a shortcut that can “Maximize” any standard Mac window – this includes Safari. So, if you are willing to pay a small amount of money, you’ll get a cool all-around app too. It’s simple and easy to use, available via the Mac App Store, and is currently maintained by the developer:

MagnetMagnet – keeps your workspace organized Activated by dragging, customizable keyboard shortcuts or via Menu bar, Magnet declutters your screen by snapping windows into organized tiles. Drag a window to the top edge of your screen to maximize it.
