Stop the presses! Wait! We don’t have presses! That’s good, since Apple has just released Migration Assistant Update for Snow Leopard, which is described somewhat blandly despite the rather irritating consequences:
This update addresses an issue with the Migration Assistant application in Mac OS X Snow Leopard that prevents transfer of your personal data, settings, and compatible applications from a Mac running Mac OS X Snow Leopard to a new Mac running Mac OS X Lion.
Although it’s unclear how prevalent this bug is (we haven’t run into migration problems during the testing of Joe Kissell’s “Take Control of Upgrading to Lion”) and Apple implies that it applies only to a new Mac running Lion, we still recommend getting this update via Software Update or the Apple Support Downloads page (where it’s a 714 KB download) before upgrading to Lion. And if you’re planning on buying a new Mac that has Lion pre-installed and migrating your data over to it from a Mac running Snow Leopard, you’d be silly not to download this Migration Assistant update first.
