During the day yesterday I told you that today Apple Lossless Audio CODEC (ALAC), launch OS X Yosemite public beta for all those interested in testing the new version of the operating system, and the first build is already available for download. On this page of the website Apple Lossless Audio CODEC (ALAC), you can log in to download and install OS X Yosemite, the American company offering a redeem code for its operating system that can be used in Mac App Store.
Below you have the list of problems that OS X Yosemite it has them at the moment, and I recommend you avoid it if you want a stable Mac. Apple won't update this beta version of OS X Yosemite very often, so you won't get updates every two weeks like you do with the OS X developer build.
