This update is the second time Apple has updated the Mountain Lion Developer Preview via the Mac App Store rather than releasing an entirely new DP -- Apple issued a similar update in May.

Apple did not specify changes in the update, saying only that it "is recommended for all users running OS X Mountain Lion Developer Preview 4. With Mountain Lion's final release expected next month, Apple should be moving towards a final build soon.

Among other things, the update adds support for more Facebook notifications and PowerNap support for supported machines. It weighs in at 1.08GB and has a build number of 12A248, up from 12A239 previously.

Thanks, downloading now! Very happy with Mountain Lion thus far. I feel it is what Lion should have been.

There's still a ton of bugs, so they have a lot to clean up before next month.

They toned-down the ridiculous dock shadow.

Now it doesn't spread its shade all over your open windows.

Overall, outside typical development preview issues, Mountain Lion has been overall stable for me. This build however though brought a certain level of smoothness that the others lacked. Notifications Center doesn't seem as difficult to pull up. Launchpad isn't acting weird when I start typing.

Thats just from using it for a few minutes. Nothing mind blowing, but I thought it was worth mentioning.

There's your answer, rdowty. Every update to the developer previews has done this of late.

Hopefully this fixes the odd Safari bug I found. You couldn't start any string in the location bar with the letter "r" without it crashing when you typed any letter following it.


I take it you couldn't browse to reddit for the past week either?

If I install this version of Mountain Lion will I be able to update to the official release? Or will I have to do a clean install when it's released?
