For those of you who've already gotten Beta Preview or Developer Preview access to, I highly recommend installing it on a separate partition on your hard drive. There have been many reported bugs and even that prevent access to the system, so if you install over your current OS, you're risking having to boot into recovery or reinstall from the ground up. Installing the Yosemite beta on a separate partition means your partition will be safe and sound, and that you won't have to use Yosemite as your primary operating system. Plus, you're free to uninstall Yosemite at any time without ruining your Mavericks partition, and you can even give that Yosemite partition's space back to Mavericks if need be.

You’ll see a disk image called “InstallESD.dmg.” This is your ticket to creating a bootable copy of Mountain Lion. Open the Disk Utility app in the Utilities folder under Applications. Drag the “InstallESD.dmg” into the white box on the left side of Disk Utility, and the disk image will be added.

Hit “Restore” and let Disk Utility work its magic. Is there a good youtube to mp3 converter for mac.
