Translating step 4
After six years of removing proprietary pentalobe screws from MacBook laptops, we can remove the six of them from the back of this laptop with our eyes closed.
We also happen to sell the prettiest pentalobe screwdriver you'll ever see, useful for all of your MacBook opening needs.
Six screws! That's the fewest we've seen on a unibody MacBook of any vintage, with 8 on the 2015 MacBook and 10 on most MacBooks Pro.
