With Apple’s 12-inch MacBook discontinued, it paved the way for the company to add new models to its lineup, which include the refreshed MacBook Air and entry-level MacBook Pro. The 12-inch MacBook is not being sold on Apple’s website any longer, and since there’s not an updated model added anywhere or mentioned in the company’s press release, it should provide a clear sign that the technology giant is most likely done with this variant of portable machines.

Additionally, Apple no longer sells the previous-generation MacBook Air, which makes sense considering that the company has now introduced two refreshes, including the one with updated processors and support for True Tone display technology. The company first introduced the 12-inch MacBook back in 2015 and in order to achieve that ultra-thin form factor, the company incorporated a Force Touch trackpad and a butterfly keyboard mechanism, the latter of which brought a torrent of problems.
