Inspect the drive to ensure that the system is running out of free space

Some issues relating to lack of storage might be difficult to determine and can even be a result of fake error logs. So, first, ensure that the system is, in fact, running out of free space. There are two methods to check available space on a hard drive:

1. Access the Apple menu and select About this Mac. Choose the Storage tab.
2. More detailed information can be found within the Disk Utility feature, which is located in the Applications folder under Utilities. Once Disk Utility is launched, select the drive connected to the Mac.

Begin by cleaning Trash

Once you are sure that the drive is actually full, the next step is to simply clean the computer (as if you were cleaning your home: you empty the trash). Open the Finder menu and choose Empty Trash. Bear in mind that some applications, such as Mail, iMovie, iPhoto, and others, have their own Trash. To clean those apps, follow the steps below:

Mail

1. Click Mailbox and choose Erase Deleted Items.
2. Select In All Account and Mailbox.
3. Finally click Erase Junk.

Alternatively, to avoid permanently losing your files, choose to archive your emails by following the steps below.

1. Open Finder.
2. In the sidebar, choose the Downloads folder. Disk image (.dmg) files commonly occupy the most unused storage space.

Remove unused applications

Unused apps in isolation might not take up a great deal of space, but the amount of hard drive storage used by them collectively can be significant. Furthermore, removing apps on Macs is simple, especially those installed through App Store.

1. To delete them, open Launchpad.
2. Click and hold the program's icon you wish to remove.
3. When the icon starts to animate, click the Delete (x) button.
