Although Apple changed its public code names to locations in California in 2013, it continued to use wine names internally until 2014. However, in 2015, Apple made the decision to switch from using wine names to using types of apples for internal code names. Original.
In 2016, Apple made the decision to consolidate its operating systems under one brand by changing Mac OS X to macOS. This name now aligns with other operating systems such as iOS, tvOS, and watchOS. This paved the way for macOS 11, the next version after Mac OS X, which was released twenty years after the initial beta of Mac OS X.
