I must have bought one like that just came that way. I like having 16 GB of RAM and I wanted 512 GB for storage purposes. I just started school and I needed a computer so I splurged and bought it. Of course that means I keep my iPhone 12 for at least another year or two. The computer is worth that though.How do you customize a refurbished MacBook from the Apple Store? There’s no way to customize these; how they’re sold is how they come.
