I have a few third-party apps from trusted developers and I'm wondering about the icons. Can I change the icons that appear in the /Applications folder and the dock for third-party apps? These appear to be in a .icns file. I have been doing graphic design for over a decade, so the graphics are not a problem. I'm just wondering what problems I would cause if I attempted to edit the icons that appear in the app bundles.
Edit: I just had a thought. I'm on El Capitan.. is this going to present a problem (SIP)?
