> Apple Community #250867747: macOS Catalina — "New TCP connections can not establish." New connections enter SYN_SENT then immediately close. Existing connections unaffected. Only a reboot fixes it.

This is a weird thing to cite if it's a macOS 26 bug. I quite regularly go over 50 days of uptime without issues so it makes sense for it to be a new bug, and maybe they had different bugs in the past with similar symptoms.

Interesting. The article mentions complaints on the forums running Catalina, so that must be something else.

As someone who also operates fleets of Macs, for years now, there is no possible way this bug predates macOS 26. If the bug description is correct, it must be a new one.

The article is written using AI, so unless you verified the complaints, the safe default assumption is that they don't exist.

It definitely exists, but it could be a completely unrelated issue.
