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

Look for the lightning-bolt symbol next to the port, or check **System Information**: hold Option, choose **Apple menu → System Information**, and select **Thunderbolt/USB4** (or **Thunderbolt**) under Hardware. It lists each Thunderbolt port and what's connected to it.

Most recent Macs have Thunderbolt on their USB-C ports, but some ports on some models are USB-only — Apple's specifications page for your model lists them. The same System Information screen also shows the connected drive and its link, which helps when a drive seems slower than it should be — see [why an SSD can be slower than advertised](https://storagestudio.us/faq/external-drives/why-is-my-external-ssd-slower-than-advertised).
