How do I uninstall Yosemite and reinstall Mavericks? My Mac automatically upgraded to yosemite and now it's frozen with a white screen.

I made the mistake of allowing the update of Yosemite when I needed to keep my Mac on Mavericks. Now my mac won't boot. Screen is frozen, white. I've tried the "control R" routine but am not clear on how to get Mavericks back. Help. Mavericks / Yosemite for Dummies please. It isn't a big deal for me to lose the files on the Mac since I have all my important files backed-up on external drives. I am wondering about my itunes however; I have my settings as such that itunes should be backed up to the cloud, but how can I be sure? My main concern is getting my original OS Mavericks back.

iMac, OS X Mavericks (10.9.5)

Do you have a Time machine backup? If you do you can restore from that drive. If your Mac came with Mavericks then you can do an internet restore and it will put it back to original factory settings. You can copy your iTunes folder and restore that later if needed.

Do a backup, preferably 2 separate ones on 2 separate drives.

Revert to a Previous OS X - Yosemite

Revert Yosemite to Mavericks

If you do revert, I'd use Setup Assistant to restore your data. This process takes a while, so do it when you won't need the computer for several hours, based on my experience.
