It looks like Apple might be renaming the name of its operating system for Mac devices. According to the Cupertino’s website for its efforts for Earth Day 2016, OS X will be rebranded to MacOS. The name is found (and is still available at the time of writing), on the webpage discussing Apple’s focus on the environment and the lifecycle of its products.
“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”
This is not the first time Apple is using MacOS as a reference, last month, an OS X 10.11.14 framework was also found with the “macOS” naming scheme. To top this off, Apple seems to be dropping the “i” for its recent products – the Apple Watch uses watchOS, and the Apple TV uses tvOS, so Apple could shifting towards a more unified naming scheme.
Of course, this is only a rumour and Apple has not made any official announcements about rebranding Mac OS X. The company is believed to make its announcement at the upcoming WWDC 2016 happening in June.
