"200 New Features" Mountain Lion slide shown at WWDC

Apple released the Golden Master (GM) version of OS X Mountain Lion to developers today. The "golden master" designation indicates that this version of the software is intended to be the final version released to the public, barring any last-minute issues. The Build is 12A269.

Apple first previewed Mountain Lion in February, highlighting many features already present in iOS, including Messages, Reminders, Notes, Notification Center, Game Center and more at that time. At WWDC, Apple announced additional features, including Dictation, iCloud Tabs, and 'Power Nap'.

We previously highlighted this video which shows off many of the new features found in Mountain Lion:


Mountain Lion will be priced at $19.99 and released to the Mac App Store in July.

[SIZE="4"]I'm honestly not that excited about this upgrade. Nothing exciting has really come out since Tiger or Leopard in my opinion. Most of these new features will be used for like 5 minutes by the mainstream user because they're just not that important (i.e. Reminders). And they also end up taking up more precious RAM & most importantly, battery life (on a laptop). Can someone name something that is really that ground breaking in this release? It just seems like things were reorganized & tweaked a bit.

P.S.
I've been in the Apple game since 1985, so I know a good Apple product when I see it. I'm not saying this is bad, but it's just not that amazing. Maybe OS 11 will be exciting?

A reminder on how to make your own USB copy. Requires a 8GB+ USB drive

*Download the installer from the app store.

*Right-click installer -> "Show Package Contents"



*Contents -> Shared Support -> InstallESD.dmg (open it/mount it)



*Open the terminal and copy this command:

open /Volumes/Mac\ OS\ X\ Install\ ESD/BaseSystem.dmg


*Now open Diskutility and "restore" BaseSystem.dmg to your USB drive.

***PLEASE NOTE THIS REQUIRES YOUR USB HAS A GUID PARTITION TABLE***

[Changing partition table to GUID]




[Restoring the DMG]


*Now open your newly restored USB drive



*System -> Installation



*Delete the link called "Packages" and then create a new folder with the same name





*Open the terminal again and copy this to it:

open /Volumes/Mac\ OS\ X\ Install\ ESD/Packages


*Copy everything in this folder to the "Packages" folder you created on your USB.





**Note this stage might take a while**



Hurray you now have a working installer.

----------------------------------------------------------------------------------------

A note:

This guide may seem different to others you have seen but it works better:

*The standard installer will copy the installation DMG to your hard drive and then re-run the installation using that. i.e you are needlessly running the install twice. My way doesn't do that.

*This installer allows you to clean install
