Having just criticised Apple for one thing, I’m going to add some praise for another. OS X 10.4.7 is a huge improvement for people like me whose home directories are mounted over AFP. I no longer get an enormous delay when I log in before I can do anything, which is great, and it seems (touch wood) to be more robust than it was before.
(Of course, just after I decided to write that, mdimportserver crashed…)
