Serious technical problems likely responsible
The Server version of the Mac OS X 10.6.5 update is now missing from Apple's download options, AppleInsider notes. The update is reportedly being plagued by a number of technical problems, which could be enough to warrant retooling. In one case, the update is said to have broken DNS and LDAP functions; in others, the code is accused of causing random drops in client and external storage connections.
The patch may also be responsible for some e-mail troubles, namely misdirected messages. Some people have complained that when it was available, the Combo version of the update would not even download properly. Apple support staff have confirmed that v10.6.5 Server is no longer available, but have not so far offered an explanation.
