Adjust its width and height point by point, in the settings.
Never over your menus
Closed, the notch never grows over the menus of the app in front.

Everything a MacBook gets.
The same notch and the same modules, whatever your Mac.
Questions
Does Hollow work on an iMac or a Mac mini?
Yes. On any Mac with macOS 14 Sonoma or later, Hollow draws a notch at the top of the screen, on a built-in or an external display.
And with my MacBook’s lid closed?
Hollow moves to the main display, the one with the menu bar.
Is it like the iPhone’s Dynamic Island?
The idea is close: the notch grows to show what is happening, then shrinks back. Hollow is an independent app, not affiliated with Apple.
Can I change its size?
Yes. In Hollow’s settings, adjust its width and height point by point.
Is it included in Hollow?
Yes. The drawn notch is part of Hollow, €9.90 once; AI agents are part of Hollow Pro. The 7-day trial includes everything.
Dynamic Island is a trademark of Apple Inc.
