Hi folks, I made a backup of Mavericks through Time Machine and went to upgrade to Yosemite. Then in Yosemite I also made a backup to Time Machine. However now I installed Mavericks again because I was having the CPU whine, no matter what I tried. I want to restore my system with the Mavericks backup but it says that the time machine backup is from a newer version...? Can I just manually delete the Yosemite backup in order to have access to the Mavericks backup?
