Make Sure You Have Plenty of Free Mac Disk Space

You may think that if you have 120 GB of storage on your Mac, then you can use 119.9 GB without issues. Unfortunately, that’s not true. Your Mac needs free disk space to use so it can manage storage and memory. Further, some apps use some disk space for temporary storage. Thus, you need to keep a certain amount of your storage open and free to keep your Mac running speedy. It’s hard to know exactly how much you need, but many experts recommend approximately 15 percent remain free. So, let’s check Mac disk space.

Check Your Disk Space

Many Macs, such as MacBook Airs, don’t come with huge hard drives because of their compact sizes. Dealing with a full hard disk is never fun—nobody wants to delete things every time you download a new movie or album.
 
To check your free disk space,
  • Open Apple icon 
  • Select About this Mac 
  • Select Storage

  1. Download CleanMyMac 3 from MacPaw.
  2. Move large files to an external hard drive.
CleanMyMac 3 is simple: it rids your MacBook Air of useless junk files, thus giving you more storage space.

Save space on your HDD with CleanMyMac 2!

If you have many large files (movies, music, photographs, etc.) sitting on your hard drive, you’re likely to see a decrease in speed. An external drive will relieve your Mac from storing huge files and once it’s not a parking garage, you’ll notice the speed and performance increase. We recommend Western Digital external hard drives for most Mac users.
