  3. Free space is the first number you see below the name of your hard drive.

    Disk space needs will vary depending on how you use your computer. In general, if you have over 15 GB of free space, you should be fine for updates and upgrades.
    Only proceed if you have less than 15 GB of free space.

  4. Click Manage... to the right of your hard drive.
  5. Under Recommendations on the left, you'll see some very easy-to-use tools to help optimize and clean up your disk space, such as optimizing the files already stored in iCloud, removing items from iTunes you've already watched or listened to, emptying the Trash automatically, and reviewing the files stored on your Mac to delete unused or old ones.

  7. Click the Time Machine Small time machine icon icon on the top-right side of your Mac, and choose Back Up Now.
