have I mentioned lately just how much I LOVE how well Apple is doing lately at locking me out of my own computer? I remember the good ol days when ROOT was ROOT and not "root with training wheels"

FYI this is how it used to work: http://www.idownloadblog.com/2014/07/16/how-to-change-app-icon-mac/

Code:
VIRTUALBOOK:/Applications/Photos.app/Contents/Resources root # csrutil status
System Integrity Protection status: enabled.


bastards! They keep turning that back on! Apparently I'm going to have to play whack-a-mole with Apple. So

Disabling SIP: https://apple.stackexchange.com/question...s-on-os-x-10-11

they recommend you turn it back on again after you're done doing whatever you naughty little user has done, OR you can just wait five minutes for Apple to turn it back on again for you!

FWIW: after you disable SIP you can change system application icons. you'll be prompted for your password when you change (or restore) them. Then just drag into dock. You may be able to cmd-click them if they're already in the dock to make them update.
