The Finder is the first thing that you see when your Mac finishes starting up. It opens automatically and stays open as you use other apps. It includes the Finder menu bar at the top of the screen and the desktop below that. It uses windows and icons to show you the contents of your Mac, iCloud Drive, and other storage devices. It's called the Finder because it helps you to find and organize your files.

Open windows and files

1. To quickly find any text string within any text file, try this from a terminal window: grep -l text to find files to look in For example, grep -l 123abc.html will list the name of any file in the current directory that ends in.html and contains the string 123abc. (That's a lower-case-L following the GREP) Quite powerful, and fairly fast.
2. How to find files via the OS X Terminal. If you need to search for files in OS X, one option it is to use the OS X Terminal application and some of its services.
3. Mac OS X includes a program called Spotlight that does more than just find files; it can do math and find word definitions, and you can download plug-ins for.

To open a window and see the files on your Mac, switch to the Finder by clicking the Finder icon (pictured above) in the Dock. Switching to the Finder also reveals any Finder windows that might be hidden behind the windows of other apps. You can drag to resize windows and use the buttons to close , minimize , or maximize windows. Learn more about managing windows.

When you see a document, app, or other file that you want to open, just double-click it.

Use Mac OS X Spotlight search to find missing files The first point of call for many people is to open Spotlight and look for the file: Press Command-Space to open Spotlight.

Change how your files are displayed

To change how files are displayed in Finder windows, use the View menu in the menu bar, or the row of buttons at the top of the Finder window. You can view files as icons , in a list , in columns , or in a gallery . And for each view, the View menu provides options to change how items are sorted and arranged, such as by kind, date, or size. Learn more about customizing views.

When you view files in a gallery, you can browse your files visually using large previews, so it's easy to identify images, videos, and all kinds of documents. Gallery View in macOS Mojave even lets you play videos and scroll through multipage documents. Earlier versions of macOS have a similar but less powerful gallery view called Cover Flow .

Use the Preview pane

The Preview pane is available in all views by choosing View > Show Preview from the menu bar. Or press Shift-Command (⌘)-P to quickly show or hide the Preview pane.

macOS Mojave enhances the Preview pane in several ways:

• More information, including detailed metadata, can be shown for each file. This is particularly useful when working with photos and media, because key EXIF data, like camera model and aperture value, are easy to locate. Choose View > Preview Options to control what information the Preview pane can show for the kind of file selected.
• Quick Actions let you easily manage or edit the selected file.

Use Quick Actions in the Preview pane

With Quick Actions in macOS Mojave, you can take actions on a file without opening an app. Quick Actions appear at the bottom of the Preview pane and vary depending on the kind of file selected.

• Rotate an image
• Mark up an image or PDF
• Combine images and PDFs into a single PDF file
• Trim audio and video files

To manage Quick Actions, click More , then choose Customize. macOS Mojave includes a standard set of Quick Actions, but Quick Actions installed by third-party apps also appear here. You can even create your own Quick Actions using Automator.

Use Stacks on your desktop
