Well, after giving up on ever having a usable G85 in OS X it seems that these drivers aren't at all bad. I recently decided to give the AIO another shot as I needed to use the scanner and I am not seeing the hideous CPU usage when idle that prior releases always gave. Too late for me to forgive the crapness of HP with their prior releases, but I can safely say that this latest and last version is OK. Overall rating is -1 star owing to the length of time it took HP to finally produce something half decent wrt to this printer.
