Apple asks developers to focus on graphics in first OS X 10.7.5 beta

Apple has supplied its development community with the first beta of OS X 10.7.5, its forthcoming maintenance update to the Lion operating system.

People familiar with the beta issued on Tuesday indicated that it is identified as build 11G15. Those testing the software have reportedly been asked to concentrate on testing graphics performance and quality along with networking reliability and performance.

Another area of focus is said to be the importing, editing or viewing of images and media. The delta download is reportedly a 937-megabyte installer, while the combo update weighs in at 1.87 gigabytes.

AppleInsider first reported on Monday that Apple was preparing to issue the first preview of OS X 10.7.5 to members of the Apple Developer Connection.

Details on what exactly has been changed in the first beta of OS X 10.7.5 remain unknown, but any fixes or updates are likely to be relatively insignificant with OS X 10.8 Mountain Lion set to hit the Mac App Store in July.

The most recent update to Lion, OS X 10.7.4, was publicly released in early May. It included a fix for a potential security flaw in FileBug.
