Apple product released means product disassembled by iFixit, the repair company that gives us all the details of the guts of the devices from Ma and other relevant manufacturers in the market, of course.
The great advantage of this machine is the new keyboard. Called Magic Keyboard, it was already present on the 16 ? MacBook Pro and has now reached Ma's best-selling notebook. And its arrival implies a subtle change: before, the Air was 3.6mm thick at the bottom and 15.6mm at the highest ; now, because of the keyboard, it got 0.5mm thicker.
The keyboard itself we already know from the disassembly of the 16 ? MacBook Pro. And it remains the same: scissor mechanism, without that silicon protection that was part of the last generation of the problematic butterfly keyboard. Let's just hope that Apple has really solved the problems with this new generation as the 16 ? MBP was released a while ago and until now there have been no complaints in this regard, we have a good indication.
The back of the computer has Pentalobe screws, with two clips securing the cover. Inside, things are very similar, but there are some differences such as a larger processor heatsink and a new cable configuration between the logic board and the trackpad. Speaking of trackpad, it is now no longer stuck under the logic board and can be easily disconnected, that is, just remove the rear cover to remove / replace the component.
The speakers are now fastened by screws, but there is still a good deal of stickers, even though they have a more "elastic release" friendly. The battery (exactly the same as the MacBook Air launched in 2018; 49.9Wh) is located under these new cables, which also helps in removing everything without interfering with the logic board. However, it also continues to be fixed with adhesives / elastic flaps.
Here, a note about these new ?elastic stickers?: iFixit stated with all the letters that they are much better than the stickers found in MacBooks Pro, which make any repair very difficult. They still prefer a lot more screws than these new adhesives, of course, but it's a step forward.
Because of these changes, the laptop gained a score of 4 out of 10 in repairability the previous generation had a score of 3. The strengths were highlighted above, while the weaknesses are the Pentalobe screws, the keyboard that remains integrated top case and the fact that the SSD and RAM remain soldered to the logic board, which, let's face it, is terrible.
