Apple has updated the combo updater for Mac OS X Server 10.6.3. Although Apple provided no details on what was changed, the only users who need to consider installing it are those who updated from Mac OS X Server 10.6.0 using the 1.0 version of the Mac OS X Server 10.6.3 Combo Update, build 10D573 (in other words, someone reinstalling Snow Leopard Server from scratch and then updating to 10.6.3 in one step). The combo updater is available via the Apple Support Downloads page, and will be presented by Software Update to those reinstalling Snow Leopard Server from scratch. (Free, 897.32 MB)
Editing iCal Events in Snow Leopard
Snow Leopard makes looking at event details in iCal easier. In the Leopard version of iCal, you had to double-click an event to reveal only some information in a pop-up box; you then needed to click the Edit button (or press Command-E) to edit an item's information. In Snow Leopard, choose Edit > Show Inspector (or press Command-Option-I) to bring up a floating inspector that provides an editable view of any items selected in your calendar.
