Apple Intel Macs and FireWire
If you bought a Mac Book Pro in 2007 or so you could get it with firewire 800, Thunderbolt 1 and a number of other connectors. A few years later they did away with every connector except USB-C, for charging and devices. The result was a thin laptop that needed dongles, and breakout boxes, for everything.
If you have a garmin device to charge you need an adaptor. If you have a firewire 400 or 800 drive you may need two or three dongles to have the right connections. If you have a lightning cable you need a dongle, to charge one Apple device with another.
