Every MacBook Pro which has a hardware model year of 2021 has a M1 Pro or M1 Max chip, and can run macOS 27 (Golden Gate).
During parts of calendar year 2021, Apple was selling two high-end Intel-based MacBook Pro models:
- MacBook Pro (16-inch, 2019). Introduced in November 2019, discontinued in October 2021.
- MacBook Pro (13-inch, 2020, Four Thunderbolt 3 ports). Introduced in May 2020, discontinued in October 2021.
These Intel-based MacBook Pros can run Tahoe - and are the only Intel-based MacBook Pros that can. They can't run the Apple-Silicon-only macOS 27 (Golden Gate).
FYI, Apple discontinued the MacBook Pro (13-inch, 2020, Two Thunderbolt 3 ports) in November 2020 - when the MacBook Pro (13-inch, M1, 2020) came out. Apple created the M-series Apple Silicon chips by scaling up designs from the iPhone and iPad world, and the plain M1 chip was ready before the M1 Pro and M1 Max chips were.
