Apple earlier mentioned during its WWDC 2020 preview that the first Mac sporting the company’s ARM-based silicon would arrive later this year. While there’s a possibility that the company might hold a series of presentations next month, fresh info found in the latest macOS Big beta reveals that the tech giant might have a total of three models being prepped for an announcement that could take place very soon.

A series of files present in macOS Big Sur beta that were found by HarckerTech on Twitter reveal that Apple intends on releasing three new Mac models. These files are located in the /System/Library folder where Apple has bundles that identify different Mac models. Though most of these files are for existing models, pay close attention to MacHardwareTypes-2020f.bundle, MacHardwareTypes-2020g.bundle, and MacHardwareTypes-2020h.bundle, as these are the three new additions that might be released later this year.
