Customize the range of menu bar icons to hide on macOS 27, then expand or collapse them with one click—without waiting for the menu bar to fill up. Built on the native menu bar mechanism, with a remembered hidden range and layout backup and restore.

Why use ShiftBar if macOS 27 already collapses menu bar icons?
macOS 27 only collapses menu bar icons automatically when menu bar space runs out. ShiftBar adds on-demand control, so you can set a hidden range before the bar gets crowded.

Does ShiftBar use the native macOS 27 menu bar mechanism?
Yes. ShiftBar builds on the native menu bar mechanism and makes its collapse behavior available on demand.
