Hey all, was trying to change the icon of my "Macintosh HD" on my iMac. I'd done this earlier on my Macbook Pro, and I had the same problem as I'm having now. I eventually got it done on the 'Book Pro but I don't remember what I had to do. When clicking "Get Info", in the left-top corner the icon isn't there. It's blank and says "png". Why does the icon not show up? I can't copy-paste it, and it's stuck that way. Please help.
