Just a week after Apple released the original beta of its upcoming OS X 10.8 Mountain Lion, the company rolled out the fourth developer preview of their new Mac operating system yesterday. It is unknown what fixes are included in the update, but its content could be substantial because it measures a hefty 1.08 GB.

It appears that the company is making the final tweaks for the OS X 10.8 before it officially launches next month. Although it is nearly done, there were reports of known issues on the Mountain Lion. This includes entering a Wi-Fi password, which occurs when an incorrect log in window is displayed every time FileVault is enabled. There were also known issues with the software’s Game Center, as well as AMD and NVIDIA graphics cards.

Introducing the OS X 10.8 Mountain Lion

Last week, Apple introduced their OS X 10.8 Mountain Lion during their annual Worldwide Developers Conference in San Francisco, California. The company’s head of Mac software Craig Federighi introduced the new operating system, and bring on the spotlight on its iCloud integration.

Included in the feature is “Documents in the Cloud”, wherein users can access their files anywhere. Also added on the iCloud website are the Notes and Reminders apps, which make it available from anywhere with the use of any Apple devices with data connection.

The OS X 10.8 will also feature the “dictation for Mac,” which will also be available for the new iPad. However, this is not the same personal voice assistant as Siri.

Apple’s upcoming Mountain Lion OS will also have the new Safari web browser. It features a unified smart search field and iCloud Tabs, which synchronizes open website across Apple devices. The web browser will also have the Tabview feature that enables users to zoom out and see all the tabs that are currently open in Safari.

Other than that, the OS X 10.8 Mountain Lion will have the Power Nap. It updates an Apple device and backs up data automatically while the machine is sleeping. Moreover, it silently refreshes data and is power-efficient. This feature will be compatible with the second-generation MacBook Air and the next-generation MacBook Pro.


The fourth developer preview of OS X 10.8 Mountain Lion is now available for download at the Mac App Store. On the other hand, the upcoming OS will be available on July for $19.99.
