I tried "tcpdump ip6 and icmp" but it says im blocking all. How would
I do what I am trying to do?
I can't quite figure out tcpdump syntax.

"tcpdump icmp6", per pcap-filter(7), does not do what you need?

with -vv it shows the mac but Is there a way to put the full packet
all on one line that I can parse the output easier

Not that I know. The -e option shows the link layer addresses at the same dump line though. Perhaps you can use that.
