I haven’t had any crashes since Monday, so I’m willing to chalk those up to being flukes. I am doing a better job of separating my beefs about GnuCash and Fink under Tiger from a genuine appreciation for the upgrade itself. A genuine upgrade of OS X, as opposed to an archive and install, has historically been less stable, but for reasons stated, I’m still reluctant to go that route unless I have to do so.
Stay tuned for breaking news on the upgrade front.
