Even with "Reduce Transparency" enabled (blur disabled) I've had times when Mission Control operates at 2 frames per second on my 13" 2013 rMBP. This never happened using Mavericks. If you try full screen zoom on Yosemite with an external display attached, it's similarly unusable.

It's good to see this get some attention. I spent a long time trying to figure out how to make full screen zoom usable with an external display.

I found if you enable the "Increase Contrast" accessibility feature, performance is improved, but it does negatively affect aesthetics.

I answered my own question about this on Apple StackExchange here:

Yosemite has been a major regression in almost every respect, I actually regret upgrading. Aside from the obvious and major performance and stability issues the major features are just plain broken. For example, try answering your phone from your computer. It takes way too long to actually pick up the call from the phone and then when you try to answer it bugs up so that in the end you can never actually answer the c…

Sorry for the ignorance, Windows user here. Can't you somehow downgrade?

You can, its actually easier than in Windows since theres no licensing issues to handle.

I am currently working on an OpenGL based UI toolkit and recently purchased a 4K monitor and a EVGA GeForce GTX 750Ti to drive the display for testing purposes. As you might expect, it appears taxing to push 4X the content over the bus or have the card render content at a high resolution.

This may not be the effect seen here, but it is the first thing that came to mind. I am not sure how well system hardware has kept up with display technology.

I feel like the entire compositor has a performance regression. This includes dragging windows, and seems to have nothing to do with transparency. When running OS X virtualized inside VMWare Fusion (which does not have hardware accelerated video drivers for the guest), Mavericks was very usable. Yosemite dropped to 2fps (measured using Quartz Debug tools). I had to use Quartz Debug (available in the Graphics Debug To…

I think a big part of it is the glass blur effect that they put on everything with yosemite.

I also feel that since iOS 7 that stability and quality has gone down a lot, or they got too ambitious with the glass blur effect.

I'm at my wits end with Yosemite. I'm very seriously considering switching to Linux or Windows. Of the numerous problems this OS has, my biggest problem is waking my rMBP from sleep. About 20% of the time, it just doesn't wake up and requires a hard shutdown. I never had that problem with Mountain Lion or Mavericks.

Remember iOS 7?

Same thing.

Who was the joker who kept insisting that iOS 7 was really better and very few complained? I warned about this, post-Jobs Apple design and attention to detail.

I answer my mobile from my iMac regularly without issues. I don't have the 'continuity' feature due to Apple's choice to block old iMacs (mine is a late-08 model), other than that, it's a bit slower at app-launching but I didn't had any major issues.

I recently updated from Mavericks to Yosemite on my 2012 rMBP. Even with no transparency on my battery life was down from 6+ hours to less than 3.5 hours! And everything is so annoyingly slow. After 3 days with Yosemite I had to use my wife's 2009 Air for something, it's running Mavericks, and wow, the speed! That day I restored from a backup and now I am back to running 10.9. My battery is back to 6+ hours, and my laptop is flying.

I also updated my iPad 3 from iOS 6 to iOS 8. Now it's unusable! So, so, so slow. And that I can't even downgrade. If you are going to screw things up, Apple, can you at least give me an option to downgrade.

I think the main problem is the monolithic aspect of the OSX and iOS. Why is the Mail or Face Time app part of the OS?

Earlier quoted context omitted.

The phone thing was infuriating. After upgrading all of a sudden every device I own would start ringing like crazy: phone, computer, Apple TV STOPS airplay because the iPad streaming to it was also buzzing like mad. I KNOW I KNOW, you can turn it off, but I hate the fact that upgrading my OS has now become "turn off the 10 gimmick features so you can get back to some level of sanity", especially because after I pick…

All of the features you've just canned, I use regularly, and don't see the huge issue that you're talking about. I receive calls on my laptop daily and I've very rarely had it fail. I find being able to reply to texts and calls insanely useful. Regardless of my anecdote all new technology is prone to bugs. To say "turn off the 10 gimmick features so you can get back to some level of sanity" is ridiculous. The feature…

If Yosemite, iOS 8 and other recent changes have shown anything, it is that that problems are not consistent across the user base -- some users are plagued by bugs, while others are somehow, inexplicably completely problem-free.

I myself have been hit hard by Yosemite bugs (graphics glitches, slowness, wifi not connecting at all, very slow wifi, Mac not coming out of sleep, AirPlay issues, Airdrop issues, Bluetooth suddenly disappearing etc., all this on a fast, fairly new MBP), but I have never experienced any iOS 8 bugs of note.

The corollary is that when someone complains, we need to take it seriously and not pretend everything is fine. Clearly many people are hit by problems, and the problems are very real.

Nope. Battery life and stability has been way better for me. And the UI improvements help a bunch. Also, the tight integration with iOS is so great.

Stability is not "completely lost"
