I have already opened my Christmas present from my wife because I couldn't wait any longer. New iMac!
. . . .
Just used Migration Assistant to move data but not apps.
The only suggestion I have for the Wiki article, Edouard, is to clarify for a new WeatherCatter that before you move any files, you need to close out of WeatherCat on the old computer.
I wish each of you a Merry Christmas and Happy New Year. Even you Exairbusdriver.
