Mac disk space analyzer

If your Mac's hard drive accumulates too many files and data, you will be notified by a message saying that Mac hard drive is full. Overfilled data stored on your Mac hard drive will result in the Mac running slow and hinder the download task. Ensuring your Mac hard drive has enough space to perform is of utmost importance, and analyzing Mac disk space for regular cleanup is the only way forward.

With a comprehensive space analysis and up-to-date cleanup, you can rest assured that your Mac performance remains fast and smooth given that the Mac hard drive won't be stacked with piles of useless files and app packages anymore.

While macOS offers a configured storage management tool in System Settings (System Preferences), it primarily lists the general storage info swallowed by each app or program, not displaying separate caches, associated files, support folders, app packages, etc. at great length. To have a thorough knowledge of the drive storage info, it is recommended to utilize a Mac disk space analyzer, which facilitates a full and detailed analysis of your Mac hard drive.

As mentioned before, the built-in Storage Management tool in Mac gives no way to know the details of Mac's hard drive space and what app files or folders are eating up the space, which makes a Mac disk space analyzer necessary here. 

By using third-party software to analyze disk space on Mac, you can master every single app file or folder that swallows your hard drive and choose to keep or remove it as wish.

Moreover, you have no path to remove system data on your Mac Storage unless you can access it to see what uses up the space, or a several error may happen due to crucial system data lack. 

While the Mac disk space analyzers like iBoysoft MagicMenu give you a solution. It scans your hard drive bit by bit and presents every file and folder lying on your Mac, and you can determine whether it can be deleted according to its name.
