It is an important rumor that has been discussed for years. to date, all Mac chips are from Intel, but the transition to ARM chips may be dated. According to various reports, both Intel and the developers expect that Macs have ARM chips starting at 202o.
We know the information from media of both prestige and Axios confirm information from Bloomberg and said that multiple sources had confirmed Apple's intentions. This information fits with that received this week, where macOS and iOS apps should merge, according to Bloomberg, starting in 2021.
In the reports to which certain media have access, we can read:
Although the company has yet to say so publicly, developers and Intel officials have privately told Axios that they expect such a move next year.
Therefore, the Marzipan project unifying both platforms starts to make sense. Although most likely let's not see a fusion of operating systems as in the case of windows, it is possible that we see more and more similar characteristics on both platforms. The first information about the Marzipan project dates from 2018 during Apple's WWDC. In this sense, Apple uses a roadmap consisting of making progressive adaptations. This is what it is doing with the incorporation to macOS of the applications: Voice Notes, News, Home and Stocks.
Some do think that rebuilding macOS for ARM is an expensive task. It is possible that for a time two types of operating systems coexist, one for Intel and one for ARM. On the other hand, the hardware part is more expensive, since Apple will have to change all its equipment to ARM chips. The first incursion is being made in the T2 chip iMac Pro, MacBook Pro 2018, as well as MacBook Air and Mac mini.
