I didn't know that was possible. Of course, I don't know a lot of things about computers. Stuff that's easy for you and others just throws me off like using my external drive. I don't understand all the ins and outs so I am at a standstill.

I am going to try to download Sierra to my old MBP and see what happens.

And at any rate, I'll bet that they didn't d/l from the App Store, but from some proprietary source that doesn't even interact with it. [/quote]
