File management is essential on a Mac. Sometimes, you might need to access Finder quickly while you use another application. Luckily, you can open Finder from anywhere in macOS with an easy global command.
If you want to quickly open Finder, just press Option+Command+Space. This opens the “Searching This Mac” window.
Apple designed this window for quick file searches. In the macOS shortcut settings, it’s officially called the “Finder Search Window.” As part of Finder, you can use its sidebar and toolbars as if it were an ordinary Finder window.
When you call up the Finder Search Window, it makes Finder the active app. From there, you can press Command+N to open a regular Finder window.
If you want to go the extra mile, you can use a third-party shortcut manager, such as Quicksilver or Spark, to create a keyboard shortcut that will open a normal Finder window.
Alternatively, you can create an Open Finder shortcut in Automator. This discussion on Superuser.com walks you through the process.
