With all due respect, everything you’re saying is ringing tons of alarm bells.Absolutely, if I buy it I will be happy to share the results. I explained to him several times what version I use, that I intend to use Profile Migration to be up and running with his machine, and that I need to run Mojave... and he said he'd done this several times, no issue. It's definitely an experienced and reputable seller, in fact I don't know how anyone can possibly have 100% feedback with thousands of transactions! There's always someone who complains. So that coupled with the return policy gives me some assurance. Thanks again, really appreciate your concern.
You’re correct, thousands of transactions and a full 100% approval is almost unheard of.
You clearly came here for some advice, that’s what everyone has given you.
If you absolutely need Mojave, no matter what this person tells you, they cannot get Mojave running without some type of hack, trick or virtual machine, and it’s very likely trying to do these things could cause plenty of errors. Remember, the computer you’re looking at still has an Intel chip and a T2 *and* a Touch Bar with Touch ID.
Installing an unsupported version of macOS on that and keeping everything working properly and all security checks in place would be an absolute miracle, and probably a major security flaw Apple should fix right away.
I guarantee you that somewhere in that listing this person is lying.
Now it *is* possible they could have the mid 2019 15 inch MacBook Pro, a different computer from the 16 inch that *can* run certain versions of Mojave, but I wouldn’t bet on it.
