Search your Mac for all kinds of files, including documents, music, photos, emails, and contacts. It also provides suggestions for Internet resources.
Spotlight
Store your files in the cloud for access from any location in the world using the Internet and your Mac, Windows PC, or mobile device. Analogous to OneDrive in Windows 10.

Perform just about any action on a Mac with a touchscreen. You can swipe with one or more fingers, tap, pinch, rotate, swipe, and drag to open and close apps and operating system features, such as Mission Control and Notification Center.
Gestures
Organize and navigate your files and folders. It’s similar to File Explorer in Windows.
Finder
Access files on a CD or DVD on another computer. This feature can’t be used to access music, movies, or copy protected software discs.
Remote Disc
Access your favorite apps with just a click. You can configure the Dock to hold shortcuts to your most-used apps so they’re only a click away. It’s similar to pinning apps to the taskbar in Windows.
Dock
Install Windows on your Mac by repartitioning your hard drive. After the installation, you can switch between Mac OS X and Windows, a convenient feature for those who need to work with both Mac and Windows operating systems and applications.
Boot Camp
Back up your data or schedule regular backups to an external hard drive, Apple’s Time Capsule storage unit, or a hard drive connected to an AirPort Extreme base station. You can also use Time Machine to restore data from backup.
Time Machine
Create a snapshot of an APFS file system representing system files and settings at that time, or restore from that backup. Snapshots are available in High Sierra and later, and have some similarities to Windows restore points.
Snapshot/Restore
Access the operating system through a command-line shell. You can use Terminal to execute a wide variety of commands, including configuring Time Machine backup intervals, showing hidden files in Finder, and accessing your Mac remotely. Since modern macOS is related to Unix, it’s very similar to a Linux shell.
Terminal
Force an unresponsive app to close. You can use this feature when you’re trying to troubleshoot app and system issues.
Force Quit
Troubleshoot problems or coach a user on a remote computer. This feature is especially useful when the user or computer you’re working with isn’t anywhere near your location. But it can be just as useful when you’re working with someone in the office next to yours.
