Rounded corners on a Mac: round the bottom of the screen too

Apple’s specifications say the displays of the 13-inch and 15-inch MacBook Air and of the 14-inch and 16-inch MacBook Pro “have rounded corners at the top”. To round the bottom corners as well, so the screen matches all the way round, or to round the corners of another screen, Dynamic Menu Bar draws them.

Round the corners

Dynamic Menu Bar has a Corner Rounding page in its settings. It shows a preview of your wallpaper with a ring at each corner of the screen. Tap a ring to turn its corner on or off, and scroll over it or drag it to set the roundness; hover a corner to open its menu, where you can pick the corner’s color (black by default). Each corner draws a small piece over the very tip of the screen, the part outside the curve, so the corner reads as rounded.

• Linked pairs. A row’s two corners can be linked so they share all their settings — radius, color, on or off, opacity, and above or behind; the link badge on the preview splits them.
• Above or behind. A corner draws in front, or behind: just above the wallpaper, under your app windows, and for a top corner under the menu bar’s overlay too.
• Bottom Corner Position. The bottom corners can sit above app windows, below the active window, or above the wallpaper — one setting for a linked pair, one per corner once split.
• Corner Opacity. A slider per pair, or per corner once a pair is split.
• Corner Stroke. A hairline along the rounded corners.

The Corner rounding section of the features page lists the options, and How to customize the macOS menu bar covers the rest of what the app changes along the top of the screen.

Screen corners, not window corners

This guide is about the corners of the screen. The corners of app windows are a separate thing, and nothing here changes them. For the middle of the top edge, How to hide the notch on a MacBook covers the notch.
