Sometimes, information about Apple prototypes circulates, and the M42ADP1,1 is one of them. Under this name hides the prototype of Apple’s first Intel laptop.
Let’s decipher: at least two other Intel prototypes exist, the M43ADP1,1, which is the Mac Pro prototype, and the ADP2,1, which is the Intel test platform (we’ll talk about both soon).
M42 is a code name, ADP stands for Apple Development Platform, and the 1,1 indicates that it is the first model.
Apart from a few photos (which follow), there is very little information about this model. The only significant piece is a program log that records data about the battery and indicates that this prototype had a less powerful battery than the final MacBooks. It indeed shows a capacity of 4,900 mAh, while MacBooks have a 5,600 mAh battery.
The M42ADP1,1 also has a particularity: it uses a Core Solo processor, whereas the MacBook always had a Core Duo — the Mac mini is the only model that was equipped with a Core Solo. The change was probably made towards the end of development; for example, the MacBook Pro went from 1.67/1.83 GHz at its announcement to 1.83/2 GHz at launch.
