Long before Apple releases the first beta of the next version of the Mac operating system, the new OS will be tested internally. It appears that testing is already underway for the successor to macOS 11 Big Sur.

Synium Software has found references to macOS 12 in their servers. The references appeared for the first time on 11 January 2021.

The data is very credible. While a surfer could easily fake a macOS 12 device, these accesses can be assigned to Apple's IP network.

macOS 12 will probably be presented for the first time at WWDC 2021.

Why the new system will be called macOS 12

One can safely assume that Apple switched to a completely new numbering system with Big Sur - similar to the numbering on iOS. Instead of putting a cumbersome “MacOS Ten” in front of it and referring to macOS 10.13.0 High Sierra or macOS Catalina 10.15.1, as has been the case for years, the version number will probably be numbered more simply and macOS 11 will be followed by macOS 12.

Which name will be chosen for the system has probably not yet been determined but it is likely to take inspiration from a Californian landmark.
