OS X Mavericks release date speculated to be on October 15 is hinted once again by the release of the final non-public version of the Apple OS. According to Macworld, the golden master of the OS X Mavericks for developers (OS X 10.9) will become the official 10.9.0.

This means that the official consumer download date for the OS X Mavericks is not far off. Apple has only said that the OS will be arriving “this fall” when it first announced the software at the company’s annual WWDC conference. MacWorld recommends that for those aiming to upgrade for the new OS, it’s time to start preparing your Macs for the upcoming Mavericks.

The Cupertino tech giant has not officially released system requirements according to MacWorld, but from what the Mac-focused site saw so far, the new OS supports any Mac that works with Mountain Lion and is already running on OS X 10.6.8 or later.

Base on this, models compatible with the OS X Mavericks include: iMac (Mid 2007 or newer), MacBook (Late 2008 Aluminum, or Early 2009 or newer), MacBook Air (Late 2008 or newer), MacBook Pro 13-inch (Mid 2009 or newer), MacBook Pro 15-inch (Mid/Late 2007 or newer), MacBook Pro 17-inch (Late 2007 or newer), Mac mini (Early 2009 or newer), Mac Pro (Early 2008 or newer) and Xserve (Early 2009).

Apple usually recommends Macs to have at least 8GB of free space to install the OS X update, but Macworld suggests leaving at least 15GB to 20GB. It noted that the Mavericks installer alone is likely to be around 5GB in size, and users will need some room for temporary files. It will also be helpful, before updating to the OS X Mavericks to have the latest update for the Mountain Lion.

The Mountain Lion OS X released on July 25, 2012 by Apple cost $19.99. The previous OS released in 2011, OS X Lion, cost $29.99. Pricing for the new OS X Mavericks will probably hover at the 2012-price of Mountain Lion, but won’t be surprising if it goes down to $9.99.
