In this case, you'll want to create a throwaway account on the system to set it up and use Software Update to bring the system up to the same patch level as the old one from which you're migrating.Īfter you've updated the system, you can run the migration wizard and import your profile and apps.

It's quite likely the new MacBook is running OS X 10.9.4 or older, depending on how long it was built prior to shipping and purchase. How can I proceed with Mac-to-Mac migration? I would like to avoid having to purchase new equipment if possible is there some way to update the new Mac even though I haven't set it up yet? So I assume the issue is that the old Mac is running a newer Software Update. I'm just running Mavericks, up to the newest software update. I've found sources saying this can happen when you upgrade to Yosemite, but I have not done so. Your Mac requires an upgrade before you can migrate from this source. This source contains a newer release of OS X. The old Mac appeared on the new Mac's migration screen, but with a warning sign over its icon. I just bought a new 15' MacBook Pro, brought it home, followed the Migration Assistant instructions on my old 13' Retina MacBook Pro running Mavericks (which explicitly say to install all software updates on the source machine before migration I did so, including an OS X update), powered on the new computer, and when prompted to do so connected the two via Ethernet (using two Thunderbolt adapters I do not have a Thunderbolt-to-Thunderbolt cable).
