OS X Yosemite developer preview has been available for the past month and half and in that time there have been a few updates in order to make various improvements, and as such Apple now feels it is ready to launch the public beta version.
The OS X Yosemite public beta download will go live as from tomorrow, although there is a catch, there will be no updates for the version released to the public, and so you will be installing this at your own risk.
Like all beta programs there is always a risk, and our very own developer has suffered with several of these throughout the developer preview program. There are several times where Safari crashes on him, as well as other programs, but this is to be expected.
If you signed up for the OS X beta program following the WWDC 2014 keynote, then you will be able to log-in here from tomorrow, where you will be given details as how to proceed.
However, we do know you will be given a redemption code once signed in with your Apple ID, which you can then use to download and install Yosemite.
In order to do this you need to be running Mavericks and you are advised not to install this on your main Mac device, but rather a secondary one, again this is to do with the apparent issues.
Another word of warning, features such as Handoff and SMS might not work, and so you will be unable to test these. It is a big deal to try Yosemite early, but you just have to be prepared to take the rough with the smooth, especially if you only have one Mac device.
