People familiar with the development of Mac OS X 10.6.5, the forthcoming fifth incremental release targeting Apple’s Snow Leopard operating system, have revealed that the key focus will be interfacing with iDevices running iOS 4.2, in order to support wireless printing (AirPrint).

A report by AppleInsider detailing the nature of Mac OS X 10.6.5 Build 10H555  suggests that development is coming along nicely.

According to the site, the beta, labeled build 10H555, was sent to select developers on Wednesday evening as a 614MB disk image.

The update includes roughly a dozen general operating system fixes that enhance the stability, compatibility, and security of a Mac, the site notes, paraphrasing the documentation provided with the build.

Apple reportedly lists the following changes:

- improve reliability with Microsoft Exchange servers - resolve a delay between print jobs - address a printing issue for some HP printers connected to an Airport Extreme - resolve an issue when dragging contacts from Address Book to iCal - address an issue where dragging an item from a stack causes the Dock to not automatically hide - add SSL support for uploading files to iDisk - resolve an issue with Wikipedia information not displaying correctly in Dictionary - improve performance of MainStage on certain Mac systems - resolve spacing issues with OpenType fonts - improve reliability with some Bluetooth braille displays - resolve a VoiceOver issue when browsing some web sites with Safari 5 - address stability and performance of graphics applications and games

Going by the listings, the next 10.6.5 seed may actually be the final, public release. And it should, provided that AppleInsider is right about it being “due for a release ahead of iOS 4.2.”

The build contains no known issues, and asks developers to focus their testing efforts on 3D Graphics, Printing, QuickTime, Time Machine, and USB Devices.
