wow it worked!! I almost gave up...glad you guys stuck around & kept helping me out. So is that the general icon setting I should use for changing others?

most apps i've encountered will use Icon@2x.png but some apps vary. you'll have to dig around the app and see what icon names they use and experiment until one works
 
What happens if the icon in appfile says "unknown" - I wanted to change the safari icon to the chrome one. I noticed a handful of other apps also said unknown in appfile. Thanks

if you browse to the app's folder and open info.plist, it'll tell you what the CFBundle ID is (or something like that)
