Those were the basics of pop-up Dock folders. This section explains everything you need to know. You can customize the thing to within an inch of its life, use it to control and manipulate windows in elaborate ways, or even get rid of it completely.

(Choose System Preferences→Dock, and turn off “Show indicators for open applications.”)Īpple has made it as easy as possible to like the Dock. Only a tiny black dot beneath a program’s icon tells you that it’s open-and you can even hide that, if you want. You can have dozens of programs open at once.Īnd that’s why the Dock combines the launcher and status functions of a modern operating system. “Which programs are open” approaches unimportance in macOS, where sophisticated memory-management features make it hard to run out of memory. A program should appear when you click its icon, whether it’s open or not-just as on an iPhone or an iPad. In an ideal world, this distinction should be irrelevant. In macOS, Apple combined both functions into a single strip of icons called the Dock.Īpple’s thinking goes like this: Why must you know whether a program is already running? That’s the computer’s problem, not yours. The other kept track of which programs were open at the moment for easy switching, like the taskbar (Windows) or the Application menu (Mac OS 9). One listed unopened programs until you needed them, like the Start menu (Windows) or the Launcher (Mac OS 9). For years, most operating systems maintained two lists of programs.
