Rumours were rife that Apple could be rebranding its operating system for the Mac. Suddenly this week, internet users found the term “MacOS” replacing the “OS X” on the company’s FAQ web page.

Recently, Apple’s Environment subsite was updated. The site has a section where the discussion is about its assessment for “Product Greenhouse Gas Life Cycle.” The Marshal Town notes that MacOs was mentioned at the section while other parts of Apple’s website still use “OS X” to refer to its flagship operating system.

However, it seems that now Apple has removed the term “MacOS” from its web page and used the same “OS X” term.

A software developer in March found a hidden framework in the OS X 10.11.4 which had “MacOS” in its coding. Reportedly, Guilherme Rambo found the term in a private framework known as “FlightUtilities” Rambo also stated that the feature is used to track flights; however, the El Capitan OS does not have the feature.

The private framework is said to be at “/System/Library/PrivateFrameworks/FlightUtilities.framework.” A tech website named MacMagazine had verified it. The website also claims that the rumoured operating system would be referred to as “MacOS 11” but not OS X 10.12. Rambo had said that with that framework he was able to develop a sample application.

There are several expectations associated with Apple this year. Rambo notifies that Apple would reveal more information regarding the hidden OS X framework and the planned rebranding to “MacOS” at the Worldwide Developers Conference in June. The event will see the launch of Apple’s next-generation operating system for the Mac.

In the past, Apple had used the term “MacOS” to refer to earlier versions of the Mac operating system. Till 2012, Apple sold computers with “Mac OS” but later that year the company decided to remove the word “Mac” from the branding for its operating system, simplifying it into “OS X,” notes TechCrunch.
