I can see that 12 gb is used under named "other" when I checked in system info>storage. I want to see what are these other data, so I can clean unnecessary ones. I just got this machine and don't want to fill with garbage.
MacBook Pro (Retina, 13-inch, Late 2013), iOS 7.0.4
"Other" refers to OS X itself, documents, files downloaded from the Internet, temporary files... See > http://pondini.org/OSX/LionStorage.html
You should not be worried if "Other" just takes 12 GB. If you still want to see what files you can remove, OmniDiskSweeper may help you with this task > https://www.omnigroup.com/more
How can I view individual data usage on my mac
