Three distinct Mac models are hinted at in placeholder files in the macOS Big Sur 11.0.1 beta, which suggests a possible 2020 release for those models.
A Twitter user by the handle @HarckerTech shared an image showing multiple placeholder bundles in the beta operating system, two of which were not present in the previous beta. These three placeholders indicate the possibility of three new Macs coming at the event.
Other elements are lining up to indicate new Mac releases as well. Supply chain reports suggest that the A14X will start production in Q4 2020 for use in Macs. This will be followed by production of a higher-end A14T chipset in early 2021.
Filings with the EEC show at least five Mac models are on the way.
