Identify the top bar you want to hide
The menu bar contains the Apple menu, the active app’s menus and status controls. The Dock is the app launcher at a screen edge; a browser toolbar belongs to the browser. Their visibility settings are separate, so start by identifying which one interrupts your layout.
Set automatic hiding on macOS Tahoe
Choose a mode that suits normal work. Hiding the bar can give a background a cleaner edge, but a visible menu may be easier when you frequently use app commands.
- Open Apple menu > System Settings > Menu Bar.
- Find Automatically hide and show the menu bar.
- Choose Always, On Desktop Only, In Full Screen Only or Never.
Choose desktop and full-screen behavior deliberately
Always applies automatic hiding in both contexts. On Desktop Only leaves the bar available when an app is full screen; In Full Screen Only does the reverse. Never keeps the menu bar visible. Test the mode in an ordinary window and a full-screen app, because a setting that looks correct in one can surprise you in the other.
Reveal the bar when it is hidden
Move the pointer to the top edge and select the menu you need. If you find yourself doing this constantly, choose Never or a more limited hiding mode. Do not change Dock settings to repair a menu-bar preference.
Check transparency separately from hiding
Tahoe’s Show menu bar background controls whether the wallpaper appears behind the menu bar. That appearance choice is separate from automatic hiding. Inspect menu text against both light and dark areas of your wallpaper; a transparent-looking top edge is not useful if its controls become hard to read.
Restore a visible menu bar
Return to the same setting and choose Never. If an older tutorial’s path is unavailable, use System Settings search rather than running a command that changes undocumented preferences. For a missing app status icon, inspect that app’s settings separately from the overall bar visibility.
