OS X is changing. Well, quite literally. Apple is said to be planning to rebrand its operating system OS X to MacOS. There are various hints that indicate this substantial change in nomenclature is in the offing.

Last month a MacOS was spotted instead of OS X in a framework file and earlier, Apple SVP of Worldwide Marketing Phil Schiller also hinted in an interview. Recently, a page on Apple's website also mentioned MacOS instead of OS X.

"To model customer use, we measure the power consumed by a product while it is running in a simulated scenario. Daily usage patterns are specific to each product and are a mixture of actual and modeled customer use data. Years of use, which are based on first owners, are assumed to be four years for MacOS and tvOS devices and three years for iOS and watchOS devices. More information on our product energy use is provided in our Product Environmental Reports."

While the change is yet to be confirmed, there are noises that this may be announced at WWDC in June. If at all this change happens, it will not be the first time Apple has renamed its OS. OS X was initially announced as Mac OS X. Later Apple dropped Mac from the name and it was called OS X, in 2012.

Since then, Apple has released 2 new platform-specific OS. The Apple TV runs tvOS, and the Apple Watch runs watchOS. Earlier, Apple wanted to differentiate the device from OS hence, iPhone OS became iOS in June 2010 as iOS runs on iPhones and iPads. Hence, a change in naming could be in the works, to bring OS X in line with the branding of Apple's other operating systems.
