The startup disk is the hard drive or SSD that contains your Mac’s operating system. This is Mac’s built-in drive. Unless you set up an external disk, it’s also likely where you keep all of your other local data.

This implies that your papers, movies, music, downloads, other items, macOS, and any other software installed on your computer are certainly stored on your startup disk.

When you think of it like this, it’s simple to understand how your Mac’s startup drive may fill up over time as you install more programs, upload more photographs, and write more papers.

Unfortunately, most recent Macs do not allow you to update your starting drive to increase the storage capacity.

Therefore, it is important to delete unwanted data from time to time from your Mac.

Make some Room on Your Mac’s Hard Drive

Use the built-in utilities on your Mac to optimize storage space or free up space in other ways if you need additional storage space.

Make the most of your storage area: –

  • Choose About This Mac from the Apple menu in the corner of your screen.
  • Then choose Storage. At first, the storage bar predicts how much space is consumed and how much space is available. When it’s finished calculating, it displays segments that represent various file types.

  • Refer to the amount of “available” space listed at the top of this window or in About This Mac to track your progress as you make adjustments.

Other Things to do to Free up Storage Space

  • Delete any material you don’t need, such as music, movies, or podcasts, as they can take up a lot of storage space.
  • Delete any files that are no longer required from the Downloads folder. The Downloads folder may be accessed from the Dock or the Finder’s menu bar by selecting Go > Downloads.
  • In the Mail app, delete any emails that are no longer needed. Open Messages and go to Mailbox > Erase Unwanted Mail to eliminate junk mail. Choose Mailbox > Erase Deleted Items to erase mail you’ve transferred to the Trash.
  • If your Mac is set up for multiple users, delete any users you no longer wish to have access to it or instruct them to log in to their user account and follow the procedures in this article. Also, look in the Users folder on your Macintosh HD for any undeleted data from previously deleted users.
  • Check your Macintosh HD Users folder for any shared files you no longer have to share.
  • Move some of the data to a cloud storage service like iCloud Device* or a USB drive linked to your Mac.
  • Remove any programs that you are no longer using. To do so, drag them to Trash.
  • Compress files that you don’t use very often.
