StarTech.com Dual-Laptop USB-C KVM Docking Station, Dual Monitor 4K 60Hz DisplayPort Dock, 5-Port USB Hub, GbE, 90W/45W Power Delivery to Two Laptops, Windows/Mac, 2-Host KVM Dock (129N-USBC-KVM-DOCK)

Intel Mac says the usb device is drawing too much power. Newer silicon Macs works perfect. Remember you have to install display link. There is no way to change double Shift key combination hotkey which switches computers to some other key combination. There is a bright white LED pointing at your face so I hid it with a tape.

Amazing find, after a month researching, buying and returning equipment, I found this unit. I'm able to connect a MacBook Air M3 and a DELL Vostro 14 5410, drive two 4K displays flawlessly, all ports work really well, and power distribution works for both laptops simultaneously. You do need to install a set of display app/drivers for MacOS for the MacBook to be able to extend two 4K screens.

My setup is two laptops, dual screen via DP, mouse, keyboard and other USB peripherals via USB 3.0 hub. So far it works fine for me. No issues during setup and with switching. Used an Avocent KVM switch and two Dell docking stations before which resulted in a clutter of cables and extra chargers. One of my laptops has no USB Type C but I connected this one with and C to A adapter. Only drawback that it does not charge via this connection and requires its own charger. The box is compact. There are USB connectors on the back; only in the front panel. Note some USB cameras may not work via the switch (or hub) but this is usually clearly stated in the respective manuals. I was not so pleased with the packaging and stuffing inside the Amazon box. There was hardly any protection (stuffing) inside to prevent the StarTech box from moving. Ideally the front panel should have a 1️⃣ - 2️⃣ indication LED to indicate which of the two laptops is active. Notability it almost took two months after ordering before the switch was shipped. Luckily I was not in a hurry.

Bought it to easily change between Macbook Air and work laptop (Windows), connected to two monitors, keyboard, and a mouse. Pros: - It works! Both monitors are picked up by macOS, which is fantastic - One cable connection to laptops for both peripherals and power delivery is very convenient - Having some extra USB-A and USB-C, as well as headphone jack, is neat Cons: - Switching between PC/Mac is not instant, takes 10-15 seconds to fully switch - When switching to Mac, monitors are offline until you press any key on the keyboard. I got used to it, but it's still annoying - On Mac, there are often minor display artifacts, specially in the parts of UI that involve some sort of semi-transparency (for example, when hovering over icons in the dock). Occasionally, the monitors flicker, i.e. go dark for a second. These are minor annoyances though, nothing serious - A few times dock just randomly stopped working for no apparent reason - every connected peripheral went offline, power delivery stopped. Unplugging dock's power chord and plugging it back helps, but having everything shut down in the middle of work or game session is VERY frustrating - On several occasions, keyboard/mouse straight up refused to connect to Mac (while monitors surprisingly worked), but connect without issues to Windows laptop - Also, often switching between PC/Mac just doesn't work. Turning off/on the dock usually helps, but sometimes you need to let it cool off for a while. I have this dock for about 3 months, and as the time goes, the number of issues keeps increasing, and now it's almost daily. At this point it feels like it'll just give up on me, which is certainly not I'd expect from a $400+ (CAD) product. If you're looking for a dual-monitor KVM solution for your Mac - this thing will give you ample amounts of frustration in everyday use, so I suggest looking elsewhere. On the other hand, if you have two Windows machines, it might work just fine, but for this price you can find better and more reliable alternatives anyway.

Of the 4 different dual-display KVM's that I tried , this is the easiest and most dependable. BEST SOLUTION FOR MAC. . #1 Support DIsplayLink on Mac. This is required on mac for extended desktop support. #2 ONE BUTTON PUSH to switch between computers. My setup is a 14" Macbook Pro M1 and PC Tower Ryzen 5950X/AsRock-Taichi MB/GIgabyte Titan-Ridge TB3 PCI card/RTX 3080/etc #3 Supports Huion 24" HDMI (w DVI adaptor) and its USB Pen Display input. #4 Quick recovery of display when MacBook is disconnected and then reconnected. Or when the KVM is switched off. Comparing the StarTech to the others, aside from VisionTech, all come in plain brown boxes with minimal packaging. Ordered lowest to highest price: A: VisionTek VT2900 - Nearly half the price of the others. Light weight and cheaply made feeling, Thin plastic. No support of DIsplaylink on Mac. Extended display only on PC, Mac is mirroring only. Has slower USB ports only, 1x DP 1x HDMI. B: Startech 129N-USBC-KVM-Dock - Lacking the extra HDMI port, but switching takes only 1 button push vs 2 on the others. Glowing front light is not overly bright. Plastic case, that feels solid, comparable to Targus, much better than VisionTech. Most reliable display recovery from disconnects.2x DP All other ports same between B,C,D. BEST SOLUTION FOR MAC. C: IOGEAR GUD3CDHTAA - Full metal housing, feels study and heavy weight. Has HDMI port for 3 monitor support. Macbook disconnect recovery was slower and not as reliable as the Startech, often needing to be reset. 2 button pushes (due to the HDMI port) made it confusing what PC was active. Glowing front blue LED is way too bright, and I needed to cover it. 2xDP 1xHDMI All other ports same between B,C,D. D: Targus DOCK750UsZ - Plastic case, that feels slightly more solid than Startech.. Has LED indicators on the mode switch that help reduce the confusion on 2 button presses to switch. Includes usb cables that have screws to secure them to the device. Manual provides some trouble shooting tips, something the others all lack. 2xDP 1xHDMI All other ports same between B,C,D. These are much more pricey than other KVM solutions but use far fewer cables, and offer better hub support
