Apple stole my design for OSX 10.10 (i'm kidding)
Here's a screenshot of the new OSX Yosemite.
And below it, my self themed mac (not a concept, that is my actual mac, which is like that since a few month, those are screenshots on mac mockups.)
Same menu bar, no shadow under it, helvetica neue, almost same dock, etc etc, you'll see the rest.
My icons were iOS 7 ones just for fun. i prefer the yosemite ones.
I posted my design here already, but i'm not saying apple copied me in any way of course, i'm just proud that i guessed what apple would do, and i customized my mac with no knowledge of nothing etc, which makes things more difficult, and yea, i'm just happy about it ^^ (watch my finder and the new osx finder)
