If you’re using the ATTO card along with Snow Leopard then the 2.41MP driver on their website is compatible with 10.6, but they have yet to update the website to reflect that it is. These are the drivers for 42ES coupled with the EMC Clarion system: http://attotech.com/product.php?model=80
You may want to check with Tech Support, but it appears the latest 10.5 drivers will work with 10.6
Mac OS X 10.6.2 Server is now available. This update represents a great step for environments that have either already made to, or are preparing/planning the upgrade to, Snow Leopard Server. In this update, Apple addresses the following issues (from Apple.com):
adding and removing imported users in Server Preferences
synchronizing Portable Home Directory content
using iCal web interface within select time zones
previewing and capturing dual-source video in Podcast Capture
server-side filtering of incoming mail messages
using chained digital certificates for mail services
creating images with System Image Utility
automating installation of NetRestore images
preventing brute force password attacks
using sudo command with authenticated Open Directory binding
binding to Active Directory domains with invalid service records
creation of mobile accounts for Active Directory users
correcting a problem that would cause the Software Update cache to grow excessively
In Mac OS X 10.5 and below, the default behavior was to take screenshots (command-Shift-4) by creating a file on the desktop automatically named Picture 1.png. The second file would be created as Picture 2.png and so forth. In Snow Leopard though, the screen shots are named Screen shot followed by the date (YYYY-MM-DD) and then the time (HH.MM.SS). So if I took a screen shot at 3pm today it would be called “Screen shot 2009-08-31 at 3.01.05 PM”. This keeps them showing up in the same order they otherwise would have. At first I wasn’t sure whether I liked this change, but now I’m sure that I do. The defaults commands that were used to change the default image type and the location are still applicable.
