Does the ethernet interface require a driver in MacOS?

Yes, it does. Well, it's complicated. UNI seems to have cheaped out and used the RTL8153 chipset, which many of these cheapo hub manufacturers use. Realtek (the chipset maker) hasn't released a Mac driver for this for years, and the latest one they did release is buggy and causes frequent crashes and kernel panics on the Mac. Without this Realtek driver, the Mac supplies its own "emulated" driver which basically does all the network data processing on your Mac's CPU, slowing it down and using high CPU. With the driver, this processing is done on the chip inside the Ethernet port in the hub itself, offloading it from your computer's CPU onto the hardware itself (where it's meant to be processed). So you're stuck between a rock and a hard place. Use Realtek's buggy driver and have your computer crash every few hours/days, or don't use it and have the Mac emulate the chipset as a fallback, using up your Mac CPU for no reason AND putting a limit on your maximum speeds with this hub's Ethernet. For more information, search up RTL8153 and Mac. If Uni released a new version of this hub with a better, well-supported, hardware-offloaded Ethernet chipset (and a USB-C port), I'd immediately buy that one to replace this one.

Macbook pro 16‘’ charger is 96w. Does this hub support it or is it only for smaller chargers?

I have a 16" M1 Pro MacBook Pro and when this is plugged into the Apple 96w power supply it charges the battery all the way up the battery, but System Information > Power says it's only supplying 60w, so the UNI hub is eating 36w and all that's plugged into it is an Ethernet cable, AC Charger Information: Connected: Yes ID: 0x0000 Wattage (W): 60 Family: 0xe000400a Charging: No

What are the dimensions of the 8-in-1 hub? The size listed in the Product Information seems too large to be accurate

I have the 6-port version with the same product dimensions as the 8-port version listed at 5.9 x 4 x 1.1 inches . Actual 6-port size is 3" x 1.75" x 0.75". Don't know how much wider 8-port would be, but the USB-A ports measure 7/8" apart on-center. So, 8-port version should be closer to 4" x 1.75" x 0.75"
