How to check hard drive space on MacBook

For more information, open Disk Utility by pressing Cmd + Space . From the left panel, select the disk memory level bar to check the space used.
Then click the Info button on the toolbar to show more details like Purgeable space and Available space .
Another possible method is to right-click the Macintosh HD disk icon on the left sidebar in Finder and select Get Info .

Why use extra capacity analysis software on MacBook?
While there are built-in ways to check disk space on your Mac, why use a third-party app? Here are some reasons:
Finder may incorrectly estimate hard links as another copy of the file. Even though hard links don’t take up actual disk space, Finder finds them and results in inaccurate estimates of folder sizes.
APFS, the MacFS file system instead of copying the data updates the metadata and the data on the shared disk. Finder does not understand this mechanism and incorrectly estimates free and used disk space.
Also, APFS snapshots work differently. When Time Machine creates local snapshots, the file system is aware of the changes. But neither Finder nor About This Mac show the space captured by the snapshot, which also causes an incorrect disk space estimate.
