macOS High Sierra
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:
Magnet – 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.

Divvy is an entirely new way of managing your workspace. It allows you to quickly and efficiently “divvy up” your screen into exact portions including full screen. It’s notably more expensive than Magnet.
Cinch – simple window manager
Cinch allows you to precisely resize a window simply by dragging to the left, right, or top screen edge. It’s a bit more expensive than Magnet.
BetterSnapTool – manage window positions
BetterSnapTool allows you to easily manage your window positions and sizes by either dragging them to one of the screen’s corners or to the top, left or right side of the screen. It’s the least expensive of the paid options.
Moom – Move and zoom windows
With Moom, you can easily move and zoom windows to half screen, quarter screen, or fill the screen. It is a paid app via direct download or Mac App Store.
