Mac OS X 10.6.4 to tackle issues with OpenGL, iPhoto, DVD Player

The next update to Apple's Snow Leopard operating system will pick up where Mac OS X 10.6.3 left off by tackling compatibility issues with OpenGL-based applications and bandaging glitches with first- and third-party applications.

That's according to a list of code corrections that Apple provided to some developers on Thursday alongside the second external beta of Mac OS X 10.6.4, carrying build number 10F46. It arrived roughly one week after the Mac maker issued the first external pre-release copies of the Snow Leopard update, which focused on graphics drivers, Windows file sharing, USB devices and Voice Over.

While the focus areas remain relatively the same in Thursday's build, Apple added a fix for dropped connections with Cisco VPN and thus asked developers to evaluate the overall reliability of VPN connections under the beta.

According to developers testing Mac OS X 10.6.4, other fixes are also in the cards for pairing Apple remotes with Macs, graphics anomalies that surface when editing images in iPhoto's full-screen mode, and video playback in DVD Player.

Additional code corrections reportedly target glitches with Parental Controls, erratic USB keyboard behaviors, 3D animations, and problems launching Adobe CS3 applications like Photoshop and Illustrator.
