Though it is possible for you to buy a Mac with a 750 GB hard disk, but Mac’s space will be filled up quickly if you have lots of media files such as movies, music and photos. Even a modest iTunes or iPhoto library can quickly fill up a MacBook Air’s 64GB or 128GB SSD, leaving little room for anything else. It is very terrible to have low space on Mac. For example, if the hard drive of your MacBook Pro is nearly full, it will results in problems such as MacBook Pro slow startup. But don’t worry, here we will show you how to free up disk space on Mac. Before you start freeing up space on Mac, there are things you have to do.

In order to avoid accidentally removing important files, you can backup your Mac files to Time Machine or to external hard drive first.

But you can’t uninstall apps that are part of OS X, such as Safari and Mail. And applications use caches to store various bits of information, but these files can grow very large over time and consume valuable disk space. You’d better empty these caches on Mac. More information about empting Safari cache, you can check this article: Clear Cache Safari on Mac.
Uninstall unused apps: Click the Launchpad icon in the Dock, hold down an app’s icon until all the icons begin to jiggle, then click an app’s delete button . If you later want the app, you can re-install it from the Mac App Store.
Apps that don’t have an uninstaller: In the Finder sidebar, click Applications. Drag the app from the Applications folder to the Trash (located at the end of the Dock), then choose Finder > Empty Trash.
Empty Application Caches: Most applications store their caches in one of the following two folders, and these cache files can be safely deleted, because an application will just create a new one when needed.
The system wide cache folder at /Macintosh HD/Library/Caches.
Your local user’s cache folder at ~/Library/Caches.
