Mac OS 10.4.10 Under Development
While few details are available, MacRumors has heard that Apple is in the process of gathering testers for another update to Mac OS 10.4 "Tiger." The update would bring the version number to Mac OS 10.4.10.
Apple released Mac OS 10.4.9 in March after a prolonged period of testing and refining. Despite this, some Intel iMac users have reported that the update created audio problems, which Apple has reportedly pledged to fix in the "next update."
