Yes, with the 10.6.8 upgrade and 0.9.4, I now no longer need a hub. I am running the program in hog and integer mode. All the usb ports now work without any clicks. I did the comb 10.6.8 update as I find fewer issues with them. Maybe running Onyx to repair the permissions: http://www.titanium.free.fr/viewtopic.php?f=15&t=399 and then zapping the pram: (Shutdown Mac. Hold down: Command, Option, P, R all at the same time, and press Power button. Keep holding down the buttons until Mac restarts and you hear the second startup chime.) will help. These two things have helped with some issues for me in the past. Sven

Hello: I am new here. I saw this thread on the popping issue which I had but now is gone. I have a late 2008 model Macbook Pro 2.5GHz, 17 inch. I had the popping/clicking issue which went away using a usb hub. I did not have the issue with Fidelia 1.08, so I used it as my audio software. After upgrading to OS X 10.6.8, I tried Audirvana again which upgraded to the 0.9.4 version. Now in hog/integer mode I no longer have any clicks. So I don't know if the OS X or the Audirvana upgrade or both which did the trick, but all usb ports now work fine. Haven't had time to really compare Fidelia versus Audirvana, via a quick listen both are fairly close sound wise. Sven
