Mac-Like is quite the stretch. I’ve always found KDE to be the least attractive desktop environment. It’s like the devs spent a decade copying windows and then finally realized that was a mistake and now it’s in sort of a limbo where it looks disjointed. Every kde guide I run across is a tutorial on how to make kde look like something else. Still an excellent group of devs working on it of course. My first task if I still used Linux would be how to make kde look like Enlightenment.
I agree that "mac-like" is a stretch. It's not about being pixel-perfect (as mentioned in the blog post) but rather about very different behaviors and philosophies, and of course even if you enable the optional global menu half the programs don't populate it.
