In conclusion, the iFixit rated MacBook Retina 2015 is one of the hard-to-remove and repair devices, with a score of only 1 on a 10-point scale. The details that make MacBook Retina difficult to remove and replace repair:

1. Exclusive pentalobe screw, need specialized tool to open
2. Connection cables also interfere with device removal
3. USB-C port fixed by screw, placed below the display frame, complicated to replace.
4. Batteries are mounted with glue, also need specialized heat equipment to separate, difficult to replace.
5. Details like the processor, RAM, and flash memory are soldered to the board.
6. The screen does not have a separate protective layer, but a fixed cluster, when replacing the cost will be high.
