Apple declared a couple of days ago that the pre-release version of OS X v10.8 Mountain Lion is available for registered members of the Mac Developer Program. The announcement took place only a month after the company released the previous build.

As the project is ongoing, Apple has informed developers that Mountain Lion Developer Preview 3 comes with a set of some currently unresolved issues. The problems include installation errors, iTunes syncing problems, changes in brightness settings, missing topics or icons to name but a few.

Some of the problems revolve around Java applets that cannot run in Safari. It is worth noticing that Apple has recently delivered a few Java patches, specifically designed to fight the Flashback trojan and to address Java vulnerabilities.

As there's quite a few issues, it seems that Apple still has some work ahead before releasing the new version.

Apple appears to be focusing its efforts on enhancing its Game Center as well as ensuring a smooth integration into the next OS X. Rumours say that the new version of OS X Mountain Lion will be released around "late summer."

Tech analysts expect that this new version will be able to deliver better iCloud integration as well as additional features brought from iOS.
