What macOS can my Mac run?
Open the Apple menu and choose About This Mac. Look for Chip or Processor and the model name. For a more precise match, open System Information and find Model Identifier under Hardware.
Why the exact Intel model matters
The 13-inch Intel MacBook Pro from 2020 has two variants. The four-port model supports macOS Tahoe 26, while the two-port model tops out at macOS Sequoia 15. Choose the matching model identifier if the names look similar.
The lookup covers Apple silicon and selected Intel models. For other models, check the release-by-release links in Apple’s macOS version guide. On your Mac, open System Settings → General → Software Update to see upgrades available for that device.
