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…

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.

Same with me. Before upgrading I always used to close the lid to make my macbook to sleep. The wake-up experience was good. But after upgrading, after waking up the system becomes too slow to use. I have to restart. So stopped putting my mac book pro to sleep. Now I always have to shut down when not using. Apart from sleep-wakeup problem, in general this has become much slower compared to mavericks

Probably this could be related to hardware config. I have a mac book pro at work with 8GB ram and it works fine. My personal mac book pro has 4GB ram and it has problem.

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 you're talking about is Handoff, its 1 checkbox in your device. Airplay not working? I use it regularly again, with Plex and Beamer, its one of the most useful things I have connected. You say its ruined through software updates, but then go on to say that your gripe is the interaction interface? And of all things, scrolling. Wouldn't that be a pre-existing condition?

I feel like your frustration could be solved with just simply setting up your devices in a way that suits your uses, not the common denominator.

Quick FYI--you can disable this on your phone if you want to globally disable on all devices. It's weirdly in Settings->Facetime, as "iPhone Cellular Calls".

I've also had lots of problems with Yosemite, but I don't think this comparison is useful at all. The Hackintosh looks like a fresh install with nothing else running, whereas the rMBP has other apps running. When I don't have 100+ Safari tabs open, Yosemite runs a lot better.

My late 2014 rMBP 15" performs just like the video, and with nothing else running. It's the only thing that's disappointed me with my purchase - their flagship laptop (well, 2nd from the top, I have the 2.2GHz) should run the OS silky smooth. Like my 2010 MBP did when I bought it in 2010.

Interesting. The flashing at least seems to be an isolated System Preferences bug, as I don't remember seeing it in any other applications. Would be better to compare a larger number of UI interactions - Finder, Safari, Exposé/Mission Control, iTunes, etc., to more clearly establish a pattern rather than just claiming it anecdotally. Not saying the pattern isn't there, but proving it would be a breath of fresh in air…

Tiger didn't have Mission Control, but I certainly think there are other tests that could be done that really compare all aspects of the OS. I can tell you that Mission Control is, at times (far too frequently) extremely laggy for me on OS X Yosemite. Couple that with apps leaking memory, leaving me with mere megabytes of free RAM, and my top of the line rMBP slows to a crawl.

Dashboard has become virtually unusable in Yosemite. "Laggy" is an understatement. If I'm activating it after a restart, it can take a full minute for the widgets to become active. The same selection is available instantly in Snow Leopard. Thank goodness I've got a partitioned drive, and can switch back and forth between Y and SL as needed.

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.

This. I love the full screen zoom but had to turn it off for my thunderbolt display. Also I had a hot corner for Mission Control that was similarly laggy, had to turn that off too :(

the zoom with a thunderbolt display attached is unbearable! I really hope they fix the jankiness

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 use BeamSyncDropper v2 and have it open on startup. The only downsize is it takes a bit for the terminal window to load and execute the shell script. If you have an SSD this shouldn't be a problem, just be patient for that 2-3 seconds of painstaking peasantry. xD

Download and discussion about BeamSyncDropper can be found here: http://www.tonymacx86.com/customization/92201-beamsyncdroppe...

Also one thing about OS X running in VMWare is make sure you're using the specific CPU to the fullest potential. Graphics are rendered with the use of CPU. If you don't have the processor(s) / cores set properly you could be only at 50% overall performance. For example, I am currently using an i3 330UM. I've noticed a significant jump in performance switching from single processor 2 cores; to 2 processors 4 cores.

Personally, Mavericks outperformed Yosemite on this little machine. I've experienced long window load times, hangs, and even guest crashes since the jump... My main desktop workstation is rocking an i7-930; I WILL NOT upgrade my main VMWare workstation to Yosemite. If I need to I will just clone my current VMWare image and run Mavericks / Yosemite in tandem. I would much prefer Mavericks > Yosemite...

The graphical glitches that he notes however, happen even on a powerful, plugged-in 15" retina model. I just tried it myself. Some parts of each screen, including the blue (or grey) themed UI elements for tabs or dropdowns, take longer to move to a selected state. It's unclear whether the delay is due to the time it takes to load the preferences for the screen -- that it can't do so before you click -- or if the graphics themselves take that long to draw but already know what state they should be in. It's funny, I knew something had changed, but I couldn't pin-point it until this video. Until the side-by-side, I figured the glitches were a side-effect from it being "too fast" since there's no transition animation. But it's obvious the animated version simply felt smoother and more integrated as a UI.
