Hi everyone! My Macbookpro late 2014 can’t fetch ipv6 I have tried everything!! Restarting smc and pram. I have deleted all the files from library/preferences/systemconfiguration .Any other device i have works just fine, just my laptop wont. Tried booting in safe mode and everything worked perfect but normal mode wont!
MacBook Pro with Retina display, macOS High Sierra (10.13.1)
Use safe mode to isolate issues with your Mac - Apple SupportIf an issue doesn't happen in safe mode
If an issue doesn't happen when your Mac is started in safe mode, try restarting without pressing any keys.
- If the issue comes back, you might have incompatible login items.
- If the issue doesn't come back, it was probably caused by a cache or directory issue with your startup disk, which safe mode fixed.

I found the reason, it is the server.app (version 5.4).
IPv6 starts to work as usual after deinstallation of the server.app.

You have deleted all files by entering in system library > preferences > system configuration , this is a risky step you have to erase the HD and reinstall the OS macOS Sierra: Erase and reinstall macOS
In some countries IPV6 is still not in use , you can keep as automatic in system preferences > network .
You have to ask from your service provider , I am not getting the link how to test IPV6 , just click on it , and will show the results and searching that link in my records , if I'll found post you back .
I have the same problem after update to 10.13.2 on both iMacs but IPv6 does not fetch in safe mode too.
Interesting that in any OS in Parallels with bridged adapters to default adapter in host OS IPv6 works fine.
1) I tried to delete all files in system library > preferences > system configuration - did not help.
2) I tried to reinstall OS without erasing the system disk - did not help.
3) I did the clean install of MacOS with erasing SSD but after transferring apps, settings & files from backup - the same result.
3 MacBooks were updated without any issues.
Strange thing...
I think that is DHCP issue but I don`t know how to troubleshoot it 😟.
Once again:
"in any OS in Parallels with bridged adapters to default adapter in host OS IPv6 works fine" but in host OS the default adapter (and anyone other) is not getting an IPv6 address in the same time.
Maybe my english is bad, sorry for that 🙂.
It is my local network after router connected to ISP with native IPv6.
Before update to High Sierra 10.13.2 on two of my iMacs the ethernet adapter always got IPv6 address automatically by DHCP but now after update the same ethernet adapter is not getting IPv6 address.
But in the same time in VMs in Parallels Desktop the bridged ethernet adapter (to the ethernet adapter of the host MacOS which is not getting IPv6 address now) gets IPv6 address as always.
That`s why I think it`s some sort of software issue.
You can get more information about IPV6 on the internet , a screen shot for the link .
Here is that link What is IPv6? - Apple Support
Nice to hear .
