Launch Applications from a Finder window to learn which programs are using your hard drive space. To arrange the currently installed programs in descending order of their file sizes, select the "Show items in a list" icon from the toolbar and click the Size heading.

Clear Out Trash Cans

However, Macs may have more than one trash can, so you may have to empty several. Emptying the main trash can requires either a Ctrl-click or a right-click on the Trash icon in the far right corner of the Dock. Doing so will permanently remove whatever you've tossed in the Trash in Finder.

Remove temporary files

In all likelihood, unused temporary files are stored on your Mac's hard drive. Disk space is typically wasted on these files. Mac OS X makes an effort to delete temporary files on its own, but a specialized app will likely discover even more files that can be deleted.

While deleting temporary files may not make your Mac run faster, it will make room for new data. If you want to quickly save a little space on your hard drive, you can utilize the browser's built-in option to clean away browsing data.

Transfer some of your data to an external disk or the iCloud, particularly any files that are huge or that you won't need for some time. Select the files you wish to relocate, then drag or copy them into the destination folder. After that, you can remove the source files from your Mac.
