 ## Usage
 
-Connect the two devices via their DFU ports. That's:
- - the rear port on MacBook Air and 13" MacBook Pro
- - the port next to the MagSafe connector on the 14" and 16" MacBook Pro
- - the port nearest to the power plug on Mac Mini
+Connect the two devices via their DFU ports. The DFU port differs across devices and generations, see [How to identify the DFU port on Mac](https://support.apple.com/120694).

USB 2.0-only cables, including most cables meant for charging, will not work, as they do not have the required pins. Thunderbolt cables work too.
