os x OS X Mountain Lion Discussion

Need fixes for Thunderbolt Stability!!!! Come on Apple, lets make 10.8.1 the magic number!

Mission Control animations stutter with a handful of apps open. I had the same issue with OS X Lion until the v10.7.1 or .2 update. Now I'm back at square one again. Nice.

Try to put the dock to the side of the screen and see if it stutter then. There are people that says the new 3d dock is the reason of the stutter.

I don't like having my Dock on the side.

[nyolc8]

I don't like it either, I just said it for testing... to see if the dock is the problem or not. :)

That's insane. Mission Control starts noticeably lagging on my 2010 27-inch iMac (BTO better graphics card) with the Dock at the bottom and 7 Safari windows open. The lag is completely gone when putting the Dock on the side. Apple really needs to address this. On OS X Snow Leopard and OS X Lion I had no issues even though both have Dock reflections too.

Do you have any stacks in the dock? If so try switching them to display as folders, some users have reported that that improved performance.

[.Neo]

That didn't improve anything.

[Stetson]

You can also get the 'side dock' effect without putting the dock on the side of the screen, you just have to change a setting via the terminal:

defaults write com.apple.dock no-glass -boolean YES
[/CODE]

then

[CODE]
killall Dock
[/CODE]

To go back to the 3D dock do the same thing but change YES to NO.

I don't see any lag on a 2011 core i7 iMac with stutter when using the Mission Control and I opened like 20 tabs on Safari and a whole bunch of other applications open too hmm. What spec is your 2010 iMac?

I'm assuming it's because the ML dock has a Gaussian blur effect and the old dock didn't. It probably just needs some optimization.

I think they won't optimize it (if it's an optimizing problem)... you know... it's Apple... they want you to buy a newer mac. :/

Normally I'd agree with you, but even the latest and greatest Retina MacBook Pro can stutter on it with enough windows open. :p

Me neither. And I have a 2009 iMac. Not that I use Mission Control a lot though. But I have to admit it?s a killer feature, I don?t know why I?m still ALT+Tabbing all the time

The Dock should be using CoreImage for that, which does it all on the GPU (Same as the blur behind menus/panes), that shouldn't be the cause of any performance slowdowns.

I'm sure it's using the GPU for rendering, but that doesn't make it impervious to animation stuttering. :/

Thank You Sir, might come in handy with a low spec macbook.

Even if you have a thousand tabs open in one Safari window, it's still only one Safari window Mission Control has to render. That won't really affect performance unless Safari takes down the entire OS.

I had the same issue with OS X Lion at first. Apple fixed it later on and everything was buttery smooth again. Undoubtedly they screwed something up again.

New 10.8.3 (12D43) update for devs.

[.Neo]

Any noticeable improvements v10.8.3 brings in general?

Graphic drivers have been improving each build, less stutter in full screen apps and switching windows, Safari was crash happy in the previous build so i'll have to test that out, but other than that Mountain Lion has been very stable for me.

[.Neo]

I haven't had a single stability issue with OS X Mountain Lion on my former 2010 iMac. But then again I didn't have any with OS X Lion or Snow Leopard either. Hopefully this trend continues when I receive my new 27-inch iMac.

Same here, it's the reason why i switched 3 years ago it's very fast and stable + eye candy. :)

I recently got my hackintosh setup with my copies of Lion/Mountain I bought when I had my MBP and I have to say even on my i5 2500K OC'd to 4.5GHz, GTX 570, etc. has some stuttering even while I have full GPU rendering and everything enabled correctly thanks to tonymacx work and my compatible Z68X-UD4-B3 mobo.

[NeoWind]

Why we can't change the dock on 10.8 anymore?? Anyway to change the logicboard inside the macbook pro? alienware can easily change the graphic card to 670MX

why the luxury macbook pro doesn't have this awesome option?? Apple want to eat more money?? I hate the fact that it can't change...good product but poor performance in few years time. YUCK!

^ If you have one of the newer machines with the thunderbolt port, in near future you may very well be able to add gfx cards via the thunderbolt port. So fret not :)
