In any case, what I usually recommend that people do is take the amount of storage they’re currently using, then add on at least 50 percent more to give themselves room to grow on a new Mac.
Select your Macintosh HD (or whatever you’ve renamed your drive) on your desktop and press Command-i, and then you can see your capacity and available space there. If you guys are using an even older version of OS X (10.6 or earlier), the process is different. Then you’ll select the “Storage” tab to get an idea of how much space you’re already using on your drive. If you’re running Yosemite, you should see the redesigned window pictured below (the one where I’ve pointed out the “Storage” tab) right away, but if you’re using an earlier version of the OS, click “More Info” on the next box to get there.
An easy way to do that is to go to the Apple Menu in the upper-left of your screen and choose “About This Mac.” The first thing you’ll do is figure out how much space you’re currently using. In this article, I’m going to assume that everything you’d like to move over to a new computer is on your current Mac, but if that’s not the case (and you want to, say, put on an additional 500GB of music from an external drive), be sure to keep that in mind. The most important consideration for any machine you buy is how much storage you’ve gotta have.

Since Apple announced upgrades to the MacBook Pro and MacBook Air lines-not to mention a completely redesigned MacBook-I figured that some of you would like advice on picking a new model that meets your needs.
