Hello everybody, I recently switched from 2.4 to 2.6 with my iBook G3 and documented what changes I needed in order to get 2.6 running. It's not really a howto but a short outline of the relevant differences between 2.4. and 2.6 (howto seemed suitable for the subject). http://www.daniel-zimmermann.com/joe/ibook/ibook-2.6.html Hoping this will be useful to someone, Joe
