In macOS 27, Apple’s Menu Bar settings let you choose which status items appear, but Apple does not provide a setting for manually adjusting the spacing between menu-bar status items.
Apple describes status menus separately from Control Center and the date and time, which occupy their own areas of the menu bar.
Therefore, a setting that affects status-item spacing should not automatically be assumed to change the positioning or spacing of every element in the menu bar. Apple: Get to know your desktop, menu bar, and Dock
macOS 27 also includes an overflow mechanism that can appear when there is insufficient horizontal space for all menu-bar items.
The available space can be affected by the number and width of status items, third-party menu-bar applications, and the display's effective resolution or scaling.
Apple’s overflow behaviour should therefore be distinguished from manually adjusting the spacing between items. Apple: What’s new for enterprise in macOS 27
Removing unnecessary menu-bar items can create additional available space, but this is not the same as changing the spacing between the remaining items. Apple does not document an Apple-supported control for manually changing that spacing.
Accordingly, the most precise conclusion is: macOS 27 does not provide an Apple-supported setting for manually adjusting the spacing between menu-bar status items. This does not establish that third-party utilities or Terminal commands cannot modify the appearance; those methods would need to be evaluated individually for compatibility with macOS 27.
The statement “Apple broke the menu bar in a way that makes it difficult for others to fix. The old Terminal commands don't work either” is too categorical. The available documentation establishes the new overflow behaviour, but it does not establish that Apple “broke” the menu bar or that previous Terminal commands no longer work. Those conclusions would require separate evidence or testing.
