How to Use About This Mac and System Information

1 About This Mac

Go to > About This Mac. The About This Mac window pops up, displaying the Overview tab. The Overview tab displays the version of macOS and basic info on the processor, memory, and graphics card, along with your serial number.

2 Viewing more tabs

The About This Mac window offers up four other tabs to choose from: Displays, Storage, Support and Service. Clicking these tabs enables you to view more detailed information about each aspect of your hardware.

3 Quick links

Each area of the About window has links to related items. In the Displays tab is a Display Preferences button, while the Storage tab gives you access to the Optimise Storage feature, which helps free up space on its internal drive.

4 Using the Support links

Go to Support > macOS Resources and Mac Resources. The links take you to the Help window, a PDF manual and the macOS Support website. Under Mac Resources you’ll find links to specs, as well as hardware support.

5 Check your Service

Check the status of your Mac’s warranty in Service. Click Check my Service and Support Coverage Status and Allow to the Serial Number alert. If Apple has your registration info, it will know if your Mac is still under warranty.
