I don't get this. I currently own three Macs: an early-2013 MBP (personal), a mid-2014 MBP (work), and a 2010 Mac Mini. All three are running Yosemite and all three work as flawlessly as can be expected. Which is to say: I have not experienced a single one of the issues that OP has described here. > The iOS-like GUI and "features" such as Launchpad didn't resonate with me. Then don't use it Launchpad. I'm pretty sure I have never used Launchpad, except maybe once to see what it was, and it has neither gotten in my way nor caused any issues. I have to admit that I'm puzzled why so many people are so vocal in their complaints about it. If you don't like it remove it from the Dock and forget about it. > I spent a lot of time going through the System Preferences, figuring out what I had to turn off in order to get my sanity back. He links here to a Wikipedia page about Notification Center, the implication being that it's a pain. Any device is going to have default settings you don't personally care for. That's why they are preferences. > Messages in 10.10 is a complete shitshow. It's a stunning regression. I gave up on it shortly after Yosemite was installed. The content was frequently out-of-order, mislabeled as new, and the conversation usually unparsable. I have not experienced this even once, let alone so frequently as to make Messages unusable. > There are lots of other little things that irk me: mds being a hog, distnoted being a hog, lack of virtualization, other system services mysteriously firing up, bogging the system down. I ran into the distnoted issue on Mavericks, but it turned out to be a bug in emacs[1]. Once that fixed both disnoted and the cmd-tab problem were fixed. Other than that, thought, neither mds nor any other process has caused me any issues, ever. > It doesn't help that the Macbook Pro I have is one of those lemons that overheats easily, thus kicking the fans into "rocket taking off" mode. Oh. So there is defective hardware in the equation, but he's blaming the operating system. Ok then.
