alt Hacker NewsYes it’s doable at home, even with fairly primitive tools. You need several chemicals and (if you wish) colored dye.
Anodizing works as follows:
1. Take the MacBook apart
2. Clean it
3. Chemical bath to remove old anodized layer
4. Clean it again
5. Chemical bath with power supply attached. applied voltage+current and duration will determine hardness and thickness of the anodized layer.
6. Clean it
7. Dye it.
8. Seal the dye in a hot water bath.
It’s fairly straight forward to do.

This made me smile because in my book this is at every effect impossible, especially if the goal is getting a functioning laptop at the end of the process. To be clear, it's impossible for me because I lack the knowledge, expertise and tooling to even think about doing it.
13 year old me who anodised remote control car chassis completely agrees the process is quite simple.
In the context of a MacBook, it’s not. Removing just the aluminium components and leaving everything that doesn’t like baths undamaged is practically impossible for amateurs. I’m not sure it’s something many professionals would take on.

Otherwise known as "remove everything from the chassis, leaving only the chassis."
But do so in a way that lets you fully re-assemble it later on, after you've finished the re-anodising.

Why the dye? I thought anodising's colour comes only from the voltage used, with no dye needed.
ie you can pick the colour you want, but you need to get the voltage correct for that colour
Reversing step 1 will be the real tricky part.
Not strictly DIY because a professional anodizing workshop did the actual anodizing, but cool results nevertheless:
