Mac OS X 10.6.2

Mac OS X 10.6.2 is out.

It fixes quite a bit of issues, including a long-standing issue that I’ve had with Apple Remote Desktop, and its daemon build_hd_index freezing my machine for fifteen to thirty minutes every night at midnight.

It also fixes a rather nasty bug that deals with guest user accounts. In fact, if you have guest user accounts enabled, you should update immediately. Otherwise, I recommend waiting a few days for your production environments, for any new issues to float to the surface and get squashed.

Software RAID Problems

My friend and colleague Tom Bridge sent me a useful bit of information for those interested in the Mac Mini Server…

Mirrored Apple RAID and SoftRAID cause kernel panics under 10.6 and 10.6.1 server.”

What this means is that the Mac Mini Server is not really all that useful until they resolve this issue, and anyone updating their software RAID-based servers should hold off as well.
Further research indicates that some people feel that it has to do with custom block sizes. I was unable to ask Tom whether his experience with this bug was the result of custom block sizes or not, although I doubt he would have done so.
This probably affects Snow Leopard client as well.
