Something happend with my MacBook Air after the last update to 10.8.3. Not only mine, my wifes too.

When sending and opening a mail with a pdf attachment, the fans start spinning and Mail is soon up in 100% CPU usage.

Opening the PDF in Preview at the same time forces Previw to also use 100% on the other core.


This never happend before.


The PDF file in this case is a 66k twopage PDF made from Numbers,
