    Hi. I'm on the public beta and want to downgrade back to Yosemite. I'm wanting to use boot camp for Windows 10 and can't get it to work on the beta.

    I'm getting an error saying the partition couldn't finish.

    Thanks everyone.

    Think I got it. Found the Command+Option+R during reboot

    Did you get it working on the beta or did you downgrade to Yosemite first?

    So I had to erase the HD (which was fine. I moved my iTunes library and pics to ex Hd). Then install clean Mountain Lion (what it came with) then upgrade back to Yosemite 10.10.5 just got office and all my stuff back on. Trying the Windows 10 now.
