It's only been a couple of days since Apple released its shiny new MacBook Pros and iFixit has already torn them apart, in more ways than one. Just like its older sibling, the new 13-inch Retina notebook didn't perform that well on the repairability scale, scoring a one out of 10 -- dropping one point from its predecessor's less than impressive two. That's largely down to the same restrictions as before: a glued battery that has been positioned to cover important screws, a Retina display that is fused inside a whole unit, soldered RAM and a non-standard SSD drive. Apple's also reduced the size of the battery, relying on Intel's Haswell processor and Mavericks' improved power management to boost battery life. The same fate befalls the 15-inch model, meaning it'll be almost impossible to upgrade either of Apple's latest notebooks when they start suffering from the effects of entropy.
