This is normal. It’s called “litz wire”, you can read about it on wikipedia. It mitigates the “skin effect” that causes electrical losses to be higher at high frequencies.
-The stranded wire in the coil is called “litz wire”, it’s not regular stranded wire, it’s a bundle of separately insulated strands for the purpose of avoiding the “skin effect” for high frequencies.
-The etched copper sticker looks like it’s an RF antenna for near field communication. Ethan Zuo pointed out that eliminating hardware connectors would make data recovery harder but I believe we will eventually find out that this new magsafe standard is not only for charging but also a high bandwidth data connection that can serve the “console” functions like data recovery. So basically just as good as a physical connection.
Agreed. Totally unnecessary and super messy to deal with the battery adhesive just to get to the trackpad. Please update this guide!
