More than a month after the announcement of the Yosemite operating system in June at the WWDC (The Apple Worldwide Development Conference), Apple has finally released the trial OS X 10.10 Yosemite Public Beta, and those who have already tested the new system have a lot of good things to say about it.

Writer Ben Reid says, "The first beta, as those who downloaded and ran it on their Mac machines last month, was quite refined and non-developer friendly, and aside from a few snags, has felt about as smooth and seamless as any official release. This 5th Developer Preview however brings in even more bug fixes and general performance enhancements, and although there's not much to shout about in terms of features, it's definitely worth updating to if you latched onto the initial beta release."

He also says that the new Continuity features will seamlessly tie together Yosemite and iOS 8 and allow "creative and productive folks to work in an uninterrupted fashion at their convenience, and with improvements to a number of native apps."

Among the improvements that macrumors.com has listed include a slightly redesigned top bar of the System Preferences, the new download progress bar for the Launchpad, the new volumes and brightness HUDs, and a more transparent calculator.

The beta version has been made available to those who have signed up for the Developers Program which charges an annual fee of $99, and it will only be open to the first 1,000,000 registered users.

Interested people may just sign up with their Apple Id and password at appleseed.apple.com/sp/betaprogram . For a detailed process of how to download for free, Ben Reid's article provides step-by-step instructions.

Apple warns those who wish to try out this new system out to install it first on a secondary Mac, should there be problems that will arise in the installation of this trial version. Or you can always back up your files.

The final version will be officially available to the public in October.
