Fix some scratches on my Macbook pro please how can I repair these scratches on my Macbook pro they made me so sad.
Apple will put a new case around your existing working components for a flat rate repair - probably $350 these days, but I haven't checked.

You would want to file down the aluminum if it protrudes, but that won't look much better than the ragged dings you have shown. Unlike steel, aluminum doesn't repair well and the anodized coating that Apple performs to make the pebbled surface isn't something you can DIY replicate.

If you're just concerned with color, you might be able to get some modeling paint to make it a bit closer to the shade, but on close inspection it won't fool anyone. If that goes badly, you can still file off the paint and use sandpaper which is the last thing I would mention - that really looks bad in my opinion, so I would avoid that unless you are ready to pay for an Apple repair if you don't like what the grit of the sandpaper does to the finish.

Small metal files are much easier to control and limit the area of "rework" so unless you have sharp edges, I would leave it alone if you want to keep the area looking new as opposed to feeling smooth.
