Folks,
In case you're getting slow downloads of Yosemite this morning, you can
get it directly from
cifs://software.ecs.soton.ac.uk/software
It's in the images/apple directory. You're looking for version 10.10.0.
Just copy the installer app over to your /Applications folder and run it
from there.
Jules
