The first pre-release builds of Mac OS X 10.4.10 started circulating in Cupertino earlier this month, AppleInsider reports.
Apple is believed to be attempting to gather testers from its Apple Developer Connection members for an update to Mac OS 10.4 called '10.4.10.'
While the specific fixes this update targets are unknown at this time, Apple representatives said that there is an audio-related issue to be attended to.
Apple released Mac OS X 10.4.9 in March.
