Oh, for all those who are worried about removing the anodized finish, don't. I did this 6 months ago, and there is no "black stuff"or any other sort of residual. (AKA - My sleeves aren't dirty.) The people claiming that this will remove the anodized finish and make your laptop look bad are, quite frankly, talking out their ass. Or they are idiots. Either way, they are wrong.
Folks I'm a trained welder, blacksmith and bladesmith. I've got hunks of aluminum in my garage that I machine on my milling machine, cut on my CNC plasma cutting machine, and weld on my big ass Lincoln TIG welder. In other words, I'm experienced at working with Aluminum.
This tiny amount of area is not going to get exposed to a harsh environment because your laptop can't take it! Plus, the oil from your skin rubbing in this are will actually keep that small area further protected.
Note that I used a file and did this by hand. That is because the file removes metal as shavings - not dust. I would highly NOT recommend doing this with sandpaper or another abrasive. As you can see from the video the shavings are too big to become airborne and can be swept right up.
Also, for those who are listening to the other camp of idiots who claim that damage could come to your motherboard from getting shavings on it, know this: THERE IS ZERO CHANCE OF GETTING SHAVINGS ON THE MOTHERBOARD. Use your head people.
Finally, turn your machine off. I ONLY left mine on so people would not think this was a hoax. YES, I really did this to my MBP. And yes, I can afford it if I broke it. So guess what, I took the risk so you don't have to wonder if it can be done. Not the first time I've done something like this, nor will it be the last.
So, you've got two choices if your bothered by the sharp edge on your MacBook.
1) Listen to the guy who did it and had zero negative consequences.
2) Listen to people who did NOT do it, but who have a desperate need to sound like a metallurgist or some sort of authority despite their lack of hands on experience.
Caio! - John P.
