How do I know whether my Mac's ports support Thunderbolt?

\n

Short answer: Look for the lightning-bolt symbol by the port, or open System Information (Option-click the Apple menu) and check the Thunderbolt/USB4 section, which lists each port and what's connected. Most recent Macs have Thunderbolt on their USB-C ports, but not every port on every model.
