One of the things I noticed was that the App Store didn’t work with IPv4 turned off. I have even tried turning off IPv4 on my iMac and was still able to connect to sites like Google over IPv6 (see ).
I use an ISP called which in addition to a fixed IPv4 address gives me a block of routed IPv6 addresses, and this has always worked fine. I had also held off installing Sierra so my old machine was running El Capitan. When there were no new iMacs announced at Apple’s “Hello Again” event in October I decided to stop waiting and replace my ageing late 2009 model with an Apple refurbished late 2013 one (I had a friend who was eager to buy my old one). I've been trying to follow provided guidelines for testing out IPV6 thethering, but i couldn't find the checkbox for NAT64 on MacOS Sierra. › ∎ Ipv6 Network For Testing Mac Os Sierra ∎
