I guess Apple now has so much business it can afford to alienate or dispose of about 20-30% of its customers.
I can tolerate Yosemite, but that's hardly what I'd call high praise. It seems sort of like I've gone from high quality prime rib (Aqua based interfaces in all previous OS X's) to a McDonalds 99 cent meal (Yosemite.) It just seems so utterly unprofessional looking.
I wish someone could explain to me the rationale for this change.
20-30% of their customers? Probably more like 0.1%.
I don't know what to tell you guys other than you're just gonna have to trust the designers.
A story:
When iOS 7 was revealed I was revolted. I was at work watching the Keynote with my co-workers and we had just finish designing the new version of our iOS app. Tim Cook came on stage and everything I knew about designing interfaces for iOS was thrown out the window. The circle on the App/iTunes Store was way too big! The colors are too neon! That helvetica is a ridiculous!
My thoughts on iOS 7 were more than just an opinion; it was a test to myself and my career. Apple got me interested in UI design when I was a kid. They have a world-class set of designers who have set standards for the rest of the UI world and have always pushed the boundaries. with iOS 7, they threw those standards out the window. If I were to disagree with what they put out, does that mean I'm not a designer? It was a crucial moment in my career. It's difficult to put into words what this all meant to me.
Eventually it was clear that either two things had happened: 1) Ive took over the design team and didn't know what the **** he was doing or 2) The designers were so good at what they do that they literally looked into the future and saw where iOS's design needed to remain modern/top-tier and not go stale.
It was 2.
By the time iOS 7 was actually released and my existential crisis was over, I had already grown to love it. Everything had a reason. So many rules were broken and it was for the better.
What I'm trying to say is simple: you'll get over it. You're gonna have to try your best to not feel like that's an attack. Put your stubbornness aside. The same thing that happened to iOS is now happening to Mac and the reason designers aren't blasting Yosemite's design choices like they/we did with iOS is because we've already seen this before. Ive and his team are world class. He/they have proven that since the unveiling of the first iMac, and then the iPod, and then the iPhone. They know what they're doing. What looks "elementary" and "unprofessional" to you will soon seep in and become the standard for high-class UI. It had to happen. Shedding iOS 6 and OS X's visual weight sets them both up for the future.
If we never test ourselves and only ever accept what we're comfortable with, our OS would still (visually) probably look something like this:
