Forgive me if this has been answered already but I am a little confused on my options. I have rev. 1 installed runs great with a few minor (some unsolvable: PS/2 Keyboard) issues like my sata dvd drive and bluetooth recognizing my Microsoft optical desktop bluetooth keyboard. Will downloading and installing rev. 2 fix this or is there a method currently available for me to update 10.5.2 rev.1 to rev.2?
