My old MacBook (mid 2007) running Snow Leopard has died. I just got a new MBP Retina running Yosemite. Now, I have a few questions that I googled for answers, but I am still confused. I would appreciate any help, guide, orientation. (1) Will I have problems restoring from Time Machine, created on a MB Snow Leopard, to a new MBP running Yosemite? (2) Should I say yes when the set up assistant ask me to "restore from a back up"? My goal is to have all the files, apps, and configuration from my old Mac (passwords, iPhone on iTunes, etc) into the new one keeping the new OS. Is that possible? I'm sorry if this question is already around, I know Yosemite is pretty new and I am unaware of the difference with any other OS. Thanks in advance for your help.
