...I still have Tiger since I use a lot of recording/music production softwares, such as Logic, ProTools, etc etc. When Leopard came out I abstained myself from upgrading (BlackBook user here) because I a bunch of softwares had some problems with leopard. I guess all that must be solved now. Besides that is there anything else I should be aware of?, should I make a backup of the most important things? Or is it a smooth upgrade? thank you very much guys.
