I replaced my battery after being inspired by the instructions on the process. My MacBook is out of warranty and I suspected Apple would charge me several hundred dollars to fix it and require my laptop for at least a couple days. I didn’t like that proposition and decided to brave the DIY repair.
I bought the kit from IFixIt and received it about a week later. I’ve seen the comments about only doing the first five and last five steps. My experience with these types of things is that it’s usually best to clear as much out of the way as possible in case something goes wrong. Fortunately, little went wrong for me by following the instructions provided (well written and sufficiently descriptive).
I took my time and made sure I was patient when pulling cables as many of them have seemingly fragile locking mechanisms. Very much appreciate the author’s attention to detail and willingness to produce such a helpful work. As an homage to the DIY process, I made a time lapse of my effort (https://youtu.be/l4J6SFOrCQI).
