I’ve just finished updating my test server with Mac OSX 10.5.6. Both updates went without any problem and my setup was not affected in a negative way. Only had to get a new version of GPGmail. Every item had started after the reboot and worked according to expectations.

If you want to read more on what is affected in the updates I would suggest reading the Apple support site for the 10.5.6 update and the 2008-008 security update.

In case of doubt, please make a full bootable disk image backup with Cabon Copy Cloner before you start.

I will update my production machines this weekend when I’ve got some more spare time. If you want to be sure everything is allright please wait untill then.

Update: There was an issue with postfix, please read the update
