Mac OS X 10.6.5 was released for both Snow Leopard and Snow Leopard Server users last Wednesday. But since then, the update for Mac OS X 10.6 Server has been pulled without explanation.
Some who installed the update before it disappeared have reported issues on the Apple Discussions forums (1, 2). One person said that the update broke Lightweight Directory Access Protocol and Domain Name System functionality, while another said they had a problem with external drives.
"I've only updated a few machines to 10.6.5 so far... One of them (fresh 10.6.0 client install with 10.6.5 combo update installed) needs an AFP connection to a server (also running 10.6.5 now, but server edition), and the connection drops at some point within, usually, less than an hour..." user Robert Carneim2 wrote. "The other case is a 10.6.5 server with a Drobo connected to it, and it was all working great under 10.6.4 and earlier for over a year—now the Drobo drops off randomly. Has anyone seen similar behavior recently or ever?"
In yet another thread, some said they had issues with their mail server after updating to 10.6.5. User "lionadmin" said they now have some users receiving others' e-mails in "large amounts."
In addition, when the Mac OS X Server 10.6.5 update was released last week, some users found that the combo updater made available from Apple would download incorrectly. Links that originally led to downloads associated with the latest update to Snow Leopard Server are now met with a 404 error page.
AppleInsider contacted Apple support, which confirmed that Mac OS X Server 10.6.5 was no longer available for download. Representatives could not, however, provide an explanation as to why it was pulled. It was recommended that any user who might already have 10.6.5 installed back up their system as a precaution.
