First and foremost, it is important to note that Mac is not designed to have as much drive space as “major” computers have: although Mac mimics actual laptops, it’s not designed to have as much drive space as actual laptops do; generally, if you use your Mac every now and then, its drive space will gradually reduce after a period of time. 

Good enough, it’s possible to clean your drive space by removing junk and other by-products related to the 7 reasons—as briefly discussed in this article—why your Mac lacks sufficient drive space.

The following are 7 Reasons Why Your Mac Lacks Sufficient Drive Space

1. Application Support Files Have Accumulated in Your Drive Space

Some application support files contain a large amount of data. Usually, after you use your Mac for a period of time, you’ll find the support files of unused and uninstalled applications in the Library/Application Support Folder. If you uninstall applications but don’t delete the support folders associated with them, the support folders will continue accumulating, and gradually reduce your drive space.

2. Hidden Files Have Taken Up a Chunk of Your Drive Space

It’s normal for Mac users to hide files and forget that they exist; usually, Mac users have duplicate files. Your Mac might be cluttered with useless and hidden copies of photos, images, folders, files, and even duplicate files, both large and small alike. If you’re not the only person using your Mac, then it’s likely that the same music files, documents, and even images could have been saved twice and taken up considerable drive space.

3. Your Drive Space Cache Has Grown in Volume

The applications and system processes in your Mac create a cache which is a temporary service file. The total volume of the cache in your Mac could have grown to thousands of megabytes—or even tens of gigabytes. The problem with your cache could be that if you reduce its volume or empty it, it will still be created whenever you use an application.

4. Unused Language Files Unnecessarily Occupy Space/Have Increased in Size

Mac uses applications that have localized versions of many languages; as a result, there are often many unused language files that occupy a surprising amount of space in your drive. The unused files can even increase in size, depending on the applications installed on your Mac. You can easily and safely delete the languages you don’t use.

5. Your Logs Folder Has Been Continuously Written on

Log files don’t play a part in system performance; they are only products of your applications’ functions. In your system Library, the Logs Folder stores logs of your system, its applications, and the mobile devices that have been connected to it—if any. At times problems arise when the log files are handled in the operating system; the problems create situations whereby log files are continuously written on and gradually take up large amounts of disk space.

6. Your System Sleep Image Has Taken Up Considerable/Large Drive Space

Sleep image (“sleepimage”) is a file created by your Mac system whenever it is put in sleep mode. This “sleepimage” file, which can be small or large, is used whenever your battery is operating by discharging power during sleep. The sleep image feature is very useful if your Mac has limited drive space, and your battery can work for a long time; on the other hand, it can continue to take up considerable drive space if left unchecked.

7. Your Mobile Device(s)’s Backups Have Taken Up Considerable Drive Space

If you have a large number of mobile device backups for messages, photos, movies, music, and other files, they could possibly consume up to/more than fifty percent of your drive space, thus causing your Mac to lack drive space.


Your Mac lacks sufficient drive space because of one or many of the reasons briefly discussed above. Although cleaning your Mac can be an exhausting task, you can patiently do the cleaning process and make your Mac work faster. Freeing up drive space can also help you prevent the type of data loss that was reported in February 2021, when the  Mac operating system “Big Sur” upgrade caused data loss on any Mac that had low drive space.
