That quick rate puts Mountain Lion well ahead of OS X Lion which took three months to reach 14 percent share and currently sits at around 34.
Most likely, the quick adoption is thanks to Apple's decision to sell the upgrade for just $19.99 as a digital-only download.
Apple's update tightly integrates with cloud storage solutions for Mac users, as well as steal multiple features from iOS, the company's mobile operating system.
The OS will only be sold as a digital download, hence the cheaper price, and you must be running the latest Lion or Snow Leopard to upgrade.
Among the new features is an OS-based integration with social networking giant Facebook, microblogging giant Twitter and other services like Flickr for sharing pictures
"Power Nap" lets your computer stay "updated" even while in sleep mode, meaning your emails will autosync, software updates will download automatically, and any file backups will work as well. This feature is available to Mountain Lion users with the latest MacBook Airs or Retina Display MacBook Pros.
More notably, "Messages" will replace the former iChat system, allowing you to send instant messages to any Apple user, whether they are using an iOS device or a Mac.
Finally, the update will also bring basic dictation to your Mac, allowing you to talk into the mic and have it converted to text.
