Hi, I’m looking to buy a used imac and see that it has 10gig ethernet. I’m not very familiar with this high speed networking and need to know if it will be compatible enough to my standard 5e ethernet cable and router. I have a standard ASUS RT-AX58U Dual Band router, but I just don’t want to buy this iMac and then not be able to use the ethernet connection. Figured I would post this here because I see most 10gig posts were here. Thanks in advance!
10G is always backwards compatible with 1G and 100M, but not always backwards compatible with 2.5G or 5G.
that being said, Macs with 10Gig ethernet, also support 2.5 and 5G.
tl;dr 10Mb is the only thing that wont work.
