    I’ve also had Macs online for years without issue.

    I guess it only applies to “ephemeral” ports 49152–65535, though I’m not sure what range macOS actually uses. Wikipedia has numbers for Linux and various Windows versions but not macOS: https://en.wikipedia.org/wiki/Ephemeral_port

    So does that mean typical desktop usage, like email, web browsing, SSH, etc. would be unaffected? Anyone have any insight on this? I’m not a networking expert myself.

    I can’t believe the claim that “everything else dies” when that goes directly against observed reality.

      Ephemeral ports are used most often for outgoing traffic. Like if you connect to HTTP, the remote port is 80, but the local port could be any TCP port in the ephemeral range.
