		<title>OS X DirectoryService UUID case sensitivity</title>
		<description><![CDATA[I recently ran into an issue where some new users with LDAP based accounts did not see any CUPS shared printers. The solution turned out to be case sensitivity of the apple-generateduid attribute.

		<title>Bookmarks Not Synchronizing Over .Mac In 10.5.3</title>

Open a terminal and run: /Applications/Safari.app/Contents/SafariSyncClient.app/Contents/MacOS/SafariSyncClient --unregistersyncclient com.apple.Safari This will return NO, then run /Applications/Safari.app/Contents/SafariSyncClient.app/Contents/MacOS/SafariSyncClient --register which should return YES.]]></description>
