Apple has released Remote Desktop 3.5 Admin, an update to its remote desktop management software that introduces several reliability, usability, and compatibility improvements — at least some likely connected to the company’s recent release of Mac OS X 10.7 Lion and Mac OS X 10.7 Lion Server. An updated version of the app’s companion Dashboard widget has also been released. ($79.99 new from the Mac App Store, free update through Software Update or the Mac App Store, 25.27 MB)
Mac OS X Zip Expanding Utility
Firefox (and possibly other applications) may ask you what you want to do with .zip archives that you download from the Internet. If you want to expand them with Mac OS X (rather than StuffIt Expander), you may be unsure of which application actually does the job. You're looking for Archive Utility (in Leopard and later) or BOMArchiveHelper (in Tiger). In either case, the application is stored in Hard Drive/System/Library/Core Services/. Don't move it from there, though, or you'll confuse matters.

If you need to run Software Update on the Snow Leopard Server machine, you can ssh in and run it from the command line. Fussy, I know, but a necessary fallback sometimes when ARD doesn't work.
