It could be worse, but it doesn’t sparkle with creativity. In contrast to any kind of documentation, by the way: all the paper was printed only with legal notices. At this point you just notice that Dell is serious about certain things. Stability seems good as well: we ran our internet traffic and several gigabytes of backups over them for several days and had no problems. They are correctly recognized by the Mac (with the same product ID) and the most laborious part of the installation is thus to open the package. More importantly, they connected immediately and required no driver installation. They only get a boring name like “USB 10/100/1000 LAN” in the control panel, but we didn’t care.ĭell network adapters under macOS: Problem-free. And lo and behold: after a few seconds they were directly ready for use. We got both and connected them to a MacBook with macOS Big Sur 11.2.1.
Some vendors say that they will not work with the M1 (yet).Dell produces two USB Ethernet adapters for the network, one with a conventional USB-A and one with a modern USB-C connector. macOS includes several drivers for Aquantia Chips (at least the Intel version of macOS). Only solution is thunderbolt, but that's expensive (either Apple's Thunderbolt 3 -> Thunderbolt 2 -> Apple GbE adapter) or one of the various 10GbE adapters that use the Aquantia Chips.
There are no other USB based GbE chips that I'm aware of on the market. They must be used with a proprietary driver as they didn't supported the CDC-ECM mode. Not sure whether Realtek will rework their driver, or just abandon the Mac platform for their drivers. Apple blocked the kernel APIs for USB based NICs in Big Sur (and replaced them with DriverKit userspace APIs). Realteak had a driver for macOS up to Catalina. ) is done by the CPU instead of the NICs hardware which a) causes high cpu load during high network activity and b) can cause instability with some implementations.
In this state, there's no offloading which means: All the heavy lifting (checksumming. Instead, the NIC also supports basic CDC-ECM mode which macOS does have a driver (AppleUserECM) for. All those adapters (very likely) use the Realtek RTL8153 USB NIC.
