To see the size of a specific file or folder, click it once and then press Command-I. To see storage information about your Mac, click the Apple menu in the top-left of your screen. Choose About This Mac and click the Storage tab. For Time Machine backups, it's good to use a drive that has at least twice the storage capacity of your Mac. Some Mac users may require the ability to erase a disk or erase a hard drive from the command line on Mac OS, a task which is typically performed through the Disk Utility application from the GUI. The command line approach to disk erasure in macOS is a bit different and it requires precise syntax to insure that you are erasing the proper disk.

Choose Apple menu  > About This Mac.
Click the Support tab.
Click Specifications.
On the webpage that appears, the number of displays your Mac supports appears under Video Support or Graphics.
