I wanted to let everyone know that I downloaded and easily installed the Mac SW beta and it works absolutely fantastic!!!!!! I have tried it with all the common applications I normally use and expect audio with with no hiccups or issues. I especially love the ability to have the benefit of the superb Bongiovi Acoustics enhanced sound quality with my photo presentation, movie and online streaming applications. This is an early christmas present!!!!!!!!! (sure glad I didn't get coal - hahahaha). Will keep testing, but I am so impressed at such early flawless results. BTW, I am using it on a 20" IMAC w/2.16 GHz Intel Core Duo, 3GB 667 MHz DDR2 SDRAM, Bose Companion 2 Desktop speakers!
