Hi, I haven't ever found it in the software anywhere. It's usually physically engraved on the bottom of the MacBook Pro somewhere, but that doesn't help us. Apple usually has those designators on their site somewhere. I usually just take the 9-2 identifier and add MacBook Pro Apple and throw it into a Google search and it will come up either on Apple's site everymac.com. The before 2012 is a little misleading, but 2012 is when the retina displays and MagSafe 2 charger came out, so they're correct, but those units that you're talking about did use the 60w MagSafe 1 adaptor as you've found.

That's the kind of thing I expected to find in the system report, but I couldn't get anything other than the not-very-helpful "9,2" thing. -- Alex Hall > On Mar 17, 2018, at 23:35, Tim Kilburn <kilbu...@me.com > <mailto:kilbu...@me.com>> wrote: > > Hi, > > That machine is likely an A1278 if that helps. > > Later... > > Tim Kilburn > Fort McMurray, AB Canada > > On Mar 17, 2018, at 20:47, Alex Hall <mehg...@icloud.com > <mailto:mehg...@icloud.com>> wrote: > > Hi all, > My mother has a 2012 MacBook Pro, and the cord on the charger is finally > starting to wear out.
