While the new iMac Pro lacks the internal expansion capabilities of prior “Pro” desktop Macs, Satechi at least has some of that covered with its new Aluminum Type-C Clamp Hub Pro. Available for pre-order today and shipping in January, Satechi’s new hub connects to one of your iMac’s Thunderbolt 3 ports and then clamps onto the bottom of your iMac — either the 2017 iMac Pro, iMac Retina 4K, and 27-inch iMac Retina 5K — and provides a front-facing data-only USB-C port, three front-facing USB 3.0 ports with up to 5 Gbps data transfer speeds, and a Micro/SD card reader.
