On Mac computers, USB is available with these ports, depending on your Mac model.

They arent reversible, so a USB-A connector plugs into the port only when oriented correctly.

They both look the same, and the connector plugs into the port in either orientation.

Every USB port supports a particular USB specification, which determines the ports maximum data-transfer rate (speed) and power delivery when used with a USB cable and device that meets or exceeds that specification.

For example, if you connect a USB 3 device to USB 2 port, your device is limited to USB 2 speeds, and it cant draw more power from the port than can be delivered over USB 2.

In other words, to get the best performance, make sure that the USB port on your Mac and the USB cable to your device meet or exceed the USB specification of the device itself.
