The day it came out, I downloaded the massive (520 MB) Combo updater for 10.5.3, ran the update without problem, had to restart twice, and everything seems fine. I updated permissions before and after. On a separate topic: I was in town (Geneva) this afternoon, and saw a laptop (Acer?) with an 18.4" screen. I had never seen or heard of this size before. It was running a BluRay disk/demo. A generally impressive specification. Price CHF 1999, about $1900. I was a bit surprised or disappointed to see a PC with BluRay when there is no Mac laptop with such. I feel that Apple are no longer leading. There were about 20 other (mostly ugly) models of PC laptop with very good specifications, and low prices. Some very low. I hope for good news next week from WWDC. regards, Trevor
