Whereas I have been reading pages and pages of bad news on 10.5.6 (eg <http://www.macintouch.com/readerreports/leopard/topic4834.html#d20dec2008 >), I wanted to report that I did a combo update (over 600 Mb to download...) yesterday on my new MacBookPro 2.8, after running Applejack. I also ran Applejack on re-start. Everything seems just fine, I am pleased to say. regards, Trevor
