Mine is ALMOST flawless. One very unnoticeable one. Please share how it happened. I accidentally picked up my naked iPhone and I guess the stainless steel is harder than aluminum at it just caught the corner slightly.
I use hardshell cases which offer good scratch / dent protection. Did once drop my 2012 rMBP and got a chip in an area not protected by the case. There are a few more small chips but I have to look closely to see them. Not a big deal. Mine is in good shape cosmetically considering its age but not 100% perfect.
I can however see the "staingate" issue starting to come back since the display was replaced for it in 2016. That bothers me more than chips in the aluminum.
I have a 16", a 13" from 2016 (although purchased in 2017), and a 15" from 2014. None of them have any dents or scratches that I can notice. I'm pretty careful with my portables, and to be fair they don't get as used outside the house as much as some people's do. But the two older ones have been to Japan at least once apiece.
The last and maybe only time I dented a portable was with my first-gen MacBook Pro from 2008ish. I was putting it back in my backpack and the bag slipped out of my hands, falling to the floor with the MacBook Pro in it. It probably would have been fine but it landed on a table leg, denting part of the side by the power port. It still works fine today though.
Got a nick on the top/back so no big deal. Not really sure how I got it but when using the machine I can't see it, so that's a win. I don't take particular care with it and a year old I am happy with the wear.
My brand new MacBook Pro slipped out of a new case and literally cartwheeled along an old stone road. It got small dents on all four corners! I just put a plastic protector around it and don’t usually remember what’s underneath. It doesn’t bother me very much but next time I get a new laptop I’ll know what not to do.
Don’t get too obsessed about battle damage, folks.
My 2013 has a good bunch of scratches (especially on the bottom) and also a dent from when it fell of the table once. Still works perfectly, tho. Never really cared much about the optics. The new 16 is so far scratches and dent free. Time will tell for how long
Nothing on mine not even a hairline scuff. I had the screen replaced on my 2015 as part of the recall program and the genius guru mentioned he had never seen such a clean MacBook. Always had a hard shell on mine too tech21 with the rubberised exterior. The internal rubber compound marks the top/bottom case but that cleans off with a damp cloth.
My late 2019 MBP scratches/gouges so easily, and the worst of it, my partner did it. I replaced our 2014 MBA when the screen died in 2019 (that's not very long, Apple! ), and I was so excited to purchase a new machine because my partner had scratched/gouged the heck out of that machine, too, so badly, in fact, that my clothes would snag on the chiseled edges. The first time he ever used the new MBP, several months after I bought it, he scratched/deeply gouged it on all sides. He must bump it into the wall when he's setting it down. I saw him hit the lamp once when he was standing up. Of course he denied doing any of it.
