Apple Inc. (Nasdaq: AAPL) looks to be gearing up for something big.

The tech company is pushing for more overtime hours by certain staffers beginning Wednesday, meaning that a big release will likely be on the way soon, according to Apple Insider. Many believe the release probably will be the latest iteration of the Macintosh OS X operating system.

OS X 10.8, or Mountain Lion, likely will introduce more than 200 new features for Mac users, including an updated iCloud system, a new notification system, and Facebook integration.

In addition to prepping existing workers for overtime, Apple is also planning to bring on new temporary workers to handle the rush caused by the new product. Apple has reportedly been training staff on Mountain Lion since May.

On July 9, Apple distributed a final test version of Mountain Lion to developers, confirming that the system's final build is complete.

Mountain Lion continues Apple's trend of integrating its mobile iOS features into OS X. Starting with the last release of OS X, Lion, Apple began porting features seen on its mobile devices to its OS X operating system. Along this line, Mountain Lion will introduce Notes and Reminders as separate applications.

System requirements for Mountain Lion specify 2 GB of RAM and 8 GB of available hard-drive space, according to Apple. Additionally, any computer upgraded to 10.8 must be running at least version 10.6.8, Macworld reported.

Mountain Lion will be available as an upgrade at the Mac App Store and in Apple Stores for $19.99.
