how much storage space is on my macbook air 10.6.8?
I'd like to update my OS to Yosemite, but it says I don't have enough space. Where can i go to find that out? There isn't a "Storage" tab I can click on that shows me that nice little picture of all my junk.
Also, how can I free up space? I don't have any movies or many pictures on it. Does the "Mail" app store all my email on the computer? How can I permanently delete it off my computer, but not gmail?
MacBook Air, Mac OS X (10.6.8)
