Apple’s Macs come with Thunderbolt ports that are USB-C compliant. Depending on the model you choose, a new MacBook Pro comes with two or three of these ports. A pair of them are included in the new MacBook Air. Two Thunderbolt/USB 4 ports are included in a 24-inch iMac, and some models also have two USB-C ports. You most likely have devices that use USB-A, Thunderbolt 1, Thunderbolt 2, DisplayPort, HDMI, or another type of connection. What is the best way to link these devices? With the use of an adaptor.
