The software, labeled Mac OS X 10.5.4 build 9E6, weighed in at 55 megabyte -- just a fraction of the size of the recently released Mac OS X 10.5.3 Update's massive 420 megabyte package.
People familiar with the software say Apple has indicated to developers that there are presently no known issues with update, which address issues with iCal, digital camera decoding support, LEAP connections via AirPort, and sometimes missing HTTP headers.
More importantly, those same people say, is a fifth that will allow Creative Suite 3.0 users to once again properly work with files that reside on a remote server.
Immediately following Apple's Mac OS X 10.5.3 Update released last month, CS3 users flooded Apple and Adobe's support forums to report that they could no longer properly save files from InDesign, Photoshop, and other CS3 programs to a location on a remote server. The files would become corrupt, those users reported, rendering them useless.
In addition to evaluating the aforementioned fixes, Apple has also asked that its developers focus their testing efforts on a handful of system components once having installed build build 9E6. Among these are AirPort, iChat, print, ruby and samba.
On Tuesday, AppleInsider reported that Apple was preparing the first beta releases of Mac OS X 10.5.4 to arrive in developers' hands ahead of its annual developers conference which kicks off on Monday.
