A couple of unreleased Mac models were spotted in Steam's November 2022 survey. This survey gathers anonymous information from willing Steam users on details about their computers (including computer models, memory, CPU type, and more). Two unreleased Macs with the identifiers "Mac14,6" and "Mac15,4" were seen at the bottom of the list alongside identifiers for Apple devices like the Mac Studio, M2 MacBook Air, and 13-inch M2 MacBook Pro. The two devices were listed with 0% usage on Steam's platform, but their inclusion in the list suggests the company is testing the devices with upcoming Apple silicon chips on the gaming platform.
The "Mac14,6" was already spotted before in two separate Geekbench score entries with the M2 Max processor. That chip is rumoured to come out in the upcoming 14- and 16-inch MacBook Pros, which has been reportedly delayed to 2023.
