How did you guys make out with this. I removed everything per the guide on my 2012 15” and once I was done I sort of thought, “why did I need to remove ALL of this????” and I’m about to do this on my 2015 15” Retina. thinking I’d be just as happy to take a long time and just work carefully to remove the battery itself. I can be patient. What’s the minimal amount I need to remove? it looks like the speakers would be the primary thing and the trackpad connector.
