Jim Dalrymple at The Loop:
If Yosemite is any indication of what’s to come, Apple is treating OS X like royalty. I really do love the design overall, and I’m glad Apple chose to update the operating system like this.
I feel the same way about Yosemite that I felt when I first saw iOS 7. A bit startled at first, but quickly taken with how clean the interface was. Shortly after, I found it difficult to work in iOS 6 because it was kind of ugly. That’s where I am with OS X Yosemite. I actually don’t like going back to my MacBook Air and Mavericks anymore.
iOS 7 disrupted Apple’s design strategy for operating systems. I think that Yosemite is further proof that once we get over drastic revisions, we will find it even more painful to go back to something dated, like Mavericks. ∞
