I have a mid-2009 13" MacBook Pro still working, running 10.11 El Capitan. I would like to move it to a newer 2015 13" MacBook Pro currently running Catalina 10.15.
- Of course, making sure the new MacBook Pro has an equal or larger hard drive;
- Taking into account the old mid-2009 cannot be updated beyond 10.11;
- Not knowing if the newer 2015 MacBook Pro could run El Capitan.
My best option seems to be the following:
Using the Migration Assistant (working with OS X Snow Leopard v10.6.8 or later): make a TimeMachine backup of the mid-2009 MacBook Pro, connect the TM backup to the newer 2015 MacBook Pro, launch Migration Assistant (within the utilities folder) and select the Time Machine backup. I assume that 32-bit app will be quarantined, but everything else would work (i.e. Mail, preferences for all working apps, etc.). Would that work?
I don’t actually know if the newer 2015 MacBook Pro could run El Capitan. If it could, another option would be to clone the older MacBook Pro to the newer one and then slowly update through all version of macOS, all the way to Catalina.
