Apple Releases OS X Mountain Lion Developer Preview 3

This looks a lot less buggy than DP2 did.

A few bugs for features people rarely use (Photos in Mail, Back to My Mac, screen recording, DVD player, Help topics) and some FileVault issues that are easily fixed if you're up-to-date?

If you're not an end user and just want to fool around or develop, you'll be fine. I'd also like to note that I spent 6 hours (before being able to get back to restore to a Time Machine backup) trying to fix the mess DP2 left on my 2011 iMac.

I think we'll see DP4 mid May, GM released at WWDC with a public release on the App Store at the end of June.

Apple said late Summer, which means late August at the earliest, but most likely September.

How seamless do you think the new airplay will be with the appletv?

PS:this is my first post, been reading since 2003, long time for me to wait to get in on the fun of posting!

All Apple said was "Summer". No late or early. Just Summer.

I agree. I couldn't tolerate the bugs in DP2, but I have been on DP3 all afternoon and it is working great! No bugs encountered so far.

I will give it another day to be sure, but this one may just become my daily OS....

Yessir.

Roughly anywhere between June 20th and September 22.

Welcome!

I have really been impressed with Airplay to date. My ipad, imac, ipod touch & macbook pro all equally can "talk" to appletv to date no problem, so I have high hopes for any future versions.

How do you activate app expose from MC?

Click to expand...

If you're in MC, you can pinch out with 3 fingers + thumb to spread the windows of that app out. Very helpful when you have a lot of windows in the same app open.

Like lion.

This might be the first update I might skip based on not being impressed by what's offered.

I plus one'd you on both posts. You are right and if some people here cannot cope with someone pointing out a grammar mistake in the feature they are commenting on to the point of taking time to minus point you, they are sad.

The speed increase over lion is worth it alone, for me.

seclusion said:

Good afternoon

Does anyone know if this build boots into 32 bit?
Or is it also 64 bit only?
Damn soundcard is 32 bit only

mission control needs refinement.

Please give us an option in system preferences to turn off grouping of windows when mission control is activated. A simple option would satisfy so many people and would have zero effect on all those that negate this request.

this +100000000

You can now turn off auto save.

And finder windows display a small bar for file copying process, indicating how much of the file is copied.

That better be some blistering speeds because this list is pretty lackluster.

I do this via two finger swipe up or down. I tried what you suggested and nothing happened. But the issue with this is that they don't spread out enough. I frequently have too many windows for this to be effective. It just ends up showing me a cluster of windows.

I'm still running Cheetah (OSX 10.0) and doing well, although I still miss Mac System 7, but it's support just isn't there.

Sorry, but that's all pretty misleading... For starters, you showed the trackpad window, then compared it to the Expose window from SL...

THIS it the actual equivalent window in Lion...

and contains most of the options that were present in SL. The one thing that's missing is an option to have the windows "ungrouped", which could, as the other poster said, be accomplished using a checkbox

I updated the screenshot, I know I posted the wrong preference window, but my point still stands. Mission Control is botched.

TopToffee said:

And unless I've missed something, I can still drag from app to app using Mission Control, in much the same way that I could with Exposé...

This however, is false. If you have 3 windows open in Illustrator and another 3 open in Photoshop and you want to drag an object from illustrator to photoshop, you need to do the following;

1) Click and hold the desired object in Illustrator
2) Hit a hot corner to activate mission control (show all windows, grouped by app)
3) Hover and hold over the group of windows in Photoshop
4) Hit another hot corner to show all windows from within Photoshop
5) Hover and hold over desired open document in Photoshop
6) Let go of the object and it gets pasted in

STEPS 3 AND 4 RIGHT THERE ARE WHY MISSION CONTROL IS A FAILURE.

Expose allowed everyone to go DIRECTLY into the desired open document window of any specific application, bypassing steps three and four. Lion DID NOT make things easier, it made workflow SLOWER.

This has been complained about for the past year from Mac OS users while a huge number of Apple fanboys for some reason NEGATE this issue and dismiss even having a single checkmark in System Preferences to ungroup. ITS ONE SINGLE CHECKMARK. I don't care if Apple ships the OS with grouping turned on by default to satisfy the arrogant userbase, just so as long as they give everyone else a SINGLE OPTION.

When and WHY did the apple community start to dismiss simple options as this?!?!

They do, it is called Snow Leopard.

LOL, thats so true. Snow Leopard is amazing. I got a MacBook 2011 which came with Lion. Simple things like selecting tabs in system preferences showed lag. I couldnt understand why a new laptop with 4gb of ram, an SSD drive, an above average video card (ATI 6750M) and a Quad-Core i7 2.3ghz laptop with a clean install of Lion be THAT slow?

When I found out how badly Mission Control sucks, I got rid of Lion and even rid of the recovery partition. Went back to Snow Leopard 10.6.8 and everything has been running perfectly smooth.

I won't switch to Lion or Mountain Lion until I absolutely have to. Luckily I know that won't be anytime soon.

Install 10.6.0 and try to repeat that. SL got stable over time as well.

Mac users will be able to upgrade to Mountain Lion from the Mac App Store™ in late summer 2012.

That is a very well written suggestion complete with a descriptive example. I hope you will send that directly to Apple in the form of feedback.
