Since the latest osx update (not the combo update), i have no sound anymore except for the first sound when i boot, i checked midi settings, reinstalled lion, did a disk check etc, ram resets all the usual. I also have no flash content on any browser, i read something that the newest osx blocks older flash versions for security reasons. i updated flash like ten times now, nothing. Since I'm working in video and sound, i cannot use the computer anymore. has anyone found a solution for this? or is someone at least experiencing the same behavior on their mac? edit: i had kernel panics too every time i would boot. after the 4th lion installation it has gone now.
