What MacBook ?

Hi guys,

I search a MacBook ( priority to pro ) on eBay or something.

But, what for MacBook can I upgrade the ram ? I found a MacBook Pro from 2017, with NON touchbar. Model: A1708, for 350€. But with 8GB ram. That’s to low.

Can you tell me on what MacBooks pro can I upgrade the ram ?

Best regards

Ben
