After giving my kid the 12" rMB I have in my possession and old Macbook Pro. I will install El Capitan on the original HD, but will be getting an SSD drive to replace it. My question is do I have to clone the original hard drive to the new SSD, or can I just slap the new SSD in there and OS X will be installed via the cloud. I'm guessing not? I do have one of those external hard drive "toasters" than can mount drives to the laptop. So unless I can do a cloud install on a totally empty drive I'll clone the original hard drive to the new one with Carbon Copy Cloner and then install the new drive. Thanks for any advice. I think a memory upgrade and the SSD upgrade will give this old mac a new life.
