OS X Yosemite public beta was launched last evening by the company Apple Lossless Audio CODEC (ALAC), si I told you how you can get access to this version of the operating system for Macs. Unfortunately, some users encountered the error Code Has Already Been Redeemed when they were trying to install OS X Yosemite beta by Mac App Store, and the company Apple Lossless Audio CODEC (ALAC), has a very simple solution for everything.
According to those from Apple Lossless Audio CODEC (ALAC),, a relogin in the dedicated website OS X Yosemite public beta and an update page in which you displayed the redeem code will regenerate another code that will allow you to download the operating system. After displaying the new redeem code, you will be able to open it Mac App Store to use it to install OS X Yosemite public beta on your own Mac.
