Waiting to hear what other users report concerning any new OS patch or update, regardless of computing platform, is sound advice that I have long since taken to heart myself.

However re the most recent MacOSX security patch I failed to take my own advice and allowed the Snow Leopard version (10.6.8) security update to install on my MacBook Pro. The good news is that there have been absolutely NO issues at all as a result of this update to date.

The bottom line is that the causes of the reported problems have yet to be ascertained. However If the security patch issues become more widespread then we can be assured that a remedy will be developed and posted for downloading. Apple is generally quite good at getting that happening for users.

The simplest and most practical option is to delay installation of the update and wait for news of a revised patch.

In the meantime, if you have installed it don't panic. If nothing untoward happens after installation then things will most likely be OK. If things do seem unusual you can (a) try downloading (if you need to) and reinstalling the most recent 10.6.8 Combo Updater or (b) a little more dramatic, reboot and then do a backup from a time machine (assuming you have one of course) that predates the time of installation of the security update.

Cheers,
