I got a new USB ethernet adapter because the old one had lots of issues (hence the gist in the first place). But it still uses the same Realtek 8153 chip although am using the native driver though now, AppleUSBECM.kext
In terms of my previous issues, I remember that when I clicked the little lock in the browser to view the cert, it would crash my computer. But the disconnects that required a restart were the bigger issue. (personal reference link)
I'm currently running macOS Mojave 10.14
@zenczykowski Thanks very much for that, you’ve refined and clarified my understanding quite a bit. I’ve been about to pull the plug on a 2.5gbps USB-C adapter (I have no 2.5gbps hardware, well, apart from the other 2.5gbps dongle I bought that ended up using far too much CPU when there were lots of packets flying around to be acceptable). But then I saw someone say that the only “true” offloading one would be within the expensive kind of Thunderbolt dock (i.e. that has its own power supply and starts around £200/$200).
Are you saying that the Startech dongles (I prefer 2.5gbps because big number better, although I understand (oh how I understand) the overhead issues with USB, so unless a 5gbps dongle was Thunderbolt I’d steer clear for now) won’t cause a silly amount of CPU usage during a heavy torrenting session? If I may restate my wildest desires more flexibly/plainly: I don’t care whether it connects via USB or Thunderbolt, but a USB-C connection is preferred (but I do have adapters for both ways). I just don’t want the CPU usage to be more than e.g. watching a 4K 10bit video - I know that is being offloaded and that’s why the CPU usage is so low, but that’s kind of the point and - call me spoiled - that’s how I remember Ethernet connections behaving on my old Macs, my old PCs, etc. Certainly my 2012 MacBook Pro (non Retina, still going strong as my always on Synthogy Ivory 2 piano station) has a built in Ethernet port that does not use 30-40% CPU under heavy packet load (I am a dumb dumb, but something tells me it’s more the amount of packets rather than large packets, but something in my left shin is telling me that I just said a stupid thing)
Obviously the less it costs the better, but I would much much much rather pay twice as much for something and have efficiency and reliability.
Thank you very much for responding, I know I am by no means entitled to anybody’s assistance, and if it’s more appropriate to do this sort of thing over PM or another forum please let me know. Jungle is massive
