I feel like I should be able to do this but want to make sure there is no problems. I have two macbook pros A - 2014 15" Running Yosemite, configured exactly how I want it, backed up with time machine B - 2015 15" Running El Capital, configuration is messed up Can I just restore B to a backup from A and have basically the same computer twice? Is it okay to do that if you're going backwards in OS X versions? This would help a lot! Thanks!
