I have been reading this forum regarding the effects of the new upgrade of Leopard with some interest and for the moment I have hung back from applying the update (I am at 10.5.1 having recently installed Leopard on my machine). Given that people have experienced a variety of different problems after upgrading, I am wary of downloading and installing 10.5.2. Would users here recommend the update, as my hardware is fairly recent (see sig) and may cause fewer problems. Have Apple been able to fix some of these problems with more up-to-date hotfixes/patches? Or is it worth hanging back and waiting for a bit? While I don't need my iMac for critical purposes, it WILL be annoying if the patch causes a problem for me. If you could let me know your thoughts, I would be grateful.
