I just ordered a new 27" iMac. My current iMac has the latest OS X 10.11.2 installed. Will I have a problem if my new iMac only has OS X 10.11 and not the equal of my old iMac of OS X 10.11.2. I was hoping to migrate my old computer to my new iMac by using Set-up Assistant - so I will not know which OS is installed on it until the new iMac goes through the entire setup procedure. If I let my new iMac go through the entire set-up I could check which OS version I have but then I would have to use Migration Assistant with sharing my old iMac with my new iMac.
