So i still havent updated my MBP to 10.4.9 because I am a little nervous. I am having no problems with .8 but i have a problem where i always want the best of the best and the newest of everything. Not sure if .9 will help my computer perform better but it may make me feel better mentally because its just sitting there calling my name in software update. So my question is should i install it, whats the risk it will screw something up? TIA.
