% netstat -an | grep -c TIME_WAIT | wc -l 1

  You want to drop the wc -l. Mac `grep -c` counts lines that match, so it always prints 1 line, so piping to wc -l will always return 1. Or just open up and do netstat -an |grep TCP_WAIT and just watch it. If any don't disappear after a few minutes, then you're seeing the issue.

    They probably aren’t affected because the buggy code was only added in macOS 26: https://github.com/apple-oss-distributions/xnu/blame/f6217f891ac0bb64f3d375211650a4c1ff8ca1ea/bsd/netinet/tcp_subr.c#L3753 https://github.com/apple-oss-distributions/xnu/blame/f6217f8...

      Ouch - "every Mac" from the original post is a hallucination then. I can live with the writing style when the topic is interesting (here it was for me) but complete untruths are much worse.
