10.6.8 Server high CPU usage, hwmond culprit

It seems no matter how careful Apple is each OS update (especially server updates) reveals its own challenges for the user, that leaves them wishing that they had not left their stable platform for the bug fixes that made that update so desirable. the 10.6.8 server update was no different it claimed to fix such long time bugs as Server Side Rules which has been a thorn in the side of OSX Server Administrators everywhere who use OSX Servers as their primary email server.

Solr, WordPress & OSX Server

I have long been a fan of WordPress and not so much a fan of the search engine functionality that comes boxed with it. As an Apple Systems Admin I have several WordPress websites running on several OSX Servers. One of the sites that I administer finally got to the size to where the search capabilities of WordPress fell short of the clients desire and I was forced to look into other avenues for searching.

10.6.4 Group Calendars in iCal officially supported

Ever since Apple has given us the ability to use web based group calendars its been a cat and mouse game to get some level of support in iCal. In 10.4 when these calendars first came out it was a very cool idea give users their own calendars and give them a web interface to use it. Allow them to subscribe to their calendars in iCal which allowed the user...
