Apple's latest update to macOS Catalina appears to have broken SSH for some users.

The issue is that under Apple's macOS 10.15.4 update, released on March 24, trying to open a SSH connection to a port greater than 8192 using a server name, rather than an IP address, no longer works - for some users at least.

The Register asked Hall to elaborate on his findings but he declined, citing the possibility that the problem might be particular to his set up rather than a bug in the software Apple shipped.

A post two days ago on Apple's discussion forum complains, "After that update I am no longer able to open a SSH connection to a port greater than 8192 using server name." And three discussion participants claim they too have experienced the same issue.

One of these individuals, posting under the user name "Webdeck," filed a bug port in Open Radar, a public iOS and macOS bug reporting site created by developer Tim Burks because Apple hides its Radar bug reporting system from the public.
