Last weekend I upgraded my MacBook Pro from Leopard, Mac OS X 10.5.8, to Snow Leopard, Mac OS X 10.6. This kind of classes as early adopter behaviour as there's no bug fix release for Snow Leopard out in the wild yet to iron out any kinks or rough edges but I wasn't particularly bothered by this. I've used OS X since version Cheetah, version 10.0 and have gone through the intervening releases, Puma, Jaguar and Panther. With Tiger I stopped using a desktop machine and took a decision to make my Yahoo! supplied MacBook Pro my sole day-to-day machine, an experiment I didn't regret and which has become the norm for me. When Leopard arrived I took the early adopter plunge and upgraded and, apart from a few teething troubles, which I can't even recall now, all was well. Then Snow Leopard arrived and I waited a week, not quite early adoption but early enough. I heard no shouts and screams and even my one blocker, the lack of suitable Cisco VPN support for the version required to connect to Yahoo!, was resolved so I made sure my backup was up-to-date and upgraded. The backup gives me more foresight than I really deserve.

At first all was good. The Exchange server my corporate mail is hosted on is Exchange 2007 and at the right service pack level to work with Snow Leopard's rather stringent requirements. Mail took my authentication credentials and set up my Exchange account, iCal did the same and so did Address Book. Granted they took a while to sync up but that was over a VPN connection, over a wifi link, over my home broadband connection so some slack was cut.
