Is your Apple Mac computer low on storage volume space but you are wondering why is the storage volume on your Apple Mac computer full or the macOS System Data is showing a Huge Size in Gb?

With MacOS after you have been using macOS for a while then the storage volume might be full, or showing as nearly full. Or for some reason macOS can report a MacOS System Data Huge GB size information from the Apple menu items about this Mac and from the storage option, then manage.

The MacOS System information is a report on files that do not come under the category of Documents, Music, Video, Photos, it is often other data.

If macOS System Data is reporting a huge Gb size then a few basic Apple Mac Computer maintenance tasks can be done, and only if you have a Apple Time Machine backup in place before you start.

The first tasks to try and complete to help fix and resolve a MacOS System Data Huge Gb size.

  1. Make an Apple Time Machine backup of the computer.

2.Shut down and restart the computer with the Shift Key held down for an Intel Apple Mac computer or shut down and startup with the power button held down for a newer Apple Silicon Mac.

3. Perform a safe mode boot l, this will perform basic Apple Mac Computer maintenance tasks on the computer.

4. Now check the MacOS System information again.

If the safe mode did not resolve the problem, then there are some more steps to try.

Review the Downloads folder by choosing go Downloads and sort by size and manage any large files that are Gb in size.

Next open Apple Mac Mail and choose the Window menu and select Connection Doctor, now view the log files Window. If you find large Gb files in the Apple Mac Mail Connection Doctor log Window, the log files can be trashed.

Next, Both Microsoft Outlook and Adobe software can take away data from the computer storage, and both Adobe and Microsoft have hidden files, with Microsoft Outlook, a users profile is hidden and sometimes the profile is large causing the macOS System to include the Microsoft Outlook profile information.

For Adobe, if the Adobe Creative Suit or Adobe Cloud service has been installed or used, again this can be shown up in the macOS System storage report.

With Microsoft Outlook you can find out the user profile folder storage size by using the macOS Go menu and by opening the Microsoft profile information.

Make sure that you do not have any deleted users saved files within the Macintosh HD or storage volume, these can take up a huge amount of storage volume space.

Is the MacOS System Data size from another user profile account?

Use a MacOS software tool to help you discover hidden files.

With MacOS, a lot of the files are hidden from view, and only by using complex commands, can these files be found. One of the best ways to view files and folder sizes is to use a disk or storage viewer tool that can scan the Macintosh HD or storage volume and colour code the storage volume files.

One of the popular tools might be to use Clean My Mac software tool, however, if this does not work, or the MacOS System is reporting a huge size, then a disk tool can be used to get a view on the files that are marked as hidden.

The Apple app store has some tools that you can use to analyse the Macintosh HD storage volume there are a few Disk Space Analyser inspector tools that are available on the Apple app store to use to help. One of the popular ones to review is Disk Space Analyser.
