And if you have the older Thunderbolt 2 port, this will only accept Thunderbolt 2 cables. On a Mac, if you have Thunderbolt 3 ports, you can use both Thunderbolt and USB-C cables, but if you only have USB-C ports, you can only use USB-C cables, not Thunderbolt 3 cables. USB-A 3.0 ports can accept USB 2.0 and 3.0 cables, but we do not recommend using USB-A 3.0 cables in USB-A 2.0 ports as you may not have the desired experience. And If you have a Mac, depending on which year it was manufactured, you may have USB-A, USB-C and Thunderbolt ports. If you have a PC, I expect you’ll have either only USB-C or a combination of USB-A and USB-C ports. One of the necessary steps in getting set up for a tethered workflow is to determine which USB ports you have on your computer. We recommend checking your computer model with the manufacturer for specific details about your equipment.
