How to use previous iTunes icon? I'm have a MacBook Pro (x86_64) with OS X 10.8.5 (fully patched). When I got the MBP, the iTunes icon was a cool blue icon.

Recently, Apple changed it to red. The psychologist tell us red indicates anger, defiance and hostility, and its a bad color. Its why USAir changed their color scheme from the shades of red to shades of grey. I did not like red, but I did not feel compelled to move.

I got updates this week (July, 2015), and Apple changed the icon again:



I despise that cartoony look, and now I am compelled to move. That cartoony look is one of the reason I have held back from OS X 10.9 upgrade for my personal equipment (and even one of the reasons to abstain from iOS upgrades). This is a personal preference, and I understand only a subset of folks feel the same way.

I've been through iTunes preferences, but I don't see a way to change the icons.

How do I change the iTunes icons? Or how do I use the previous, blue icon?



Related, other reasons to abstain from the upgrade includes all the untested features and broken features that got added to 10.9. Quod erat demonstrandum: iCloud Keychain and CVE-2015-1065. My keychain was never at risk through this vector, and it was a conscious decision to avoid the risk.
There are many ways to do this. Here are a few...

IMO The best way is to replace the actual AppName.icns file with the one from the older version, in this case it's: /Applications/iTunes.app/Contents/Resources/iTunes.icns

Select the application bundle and control-click (right-click) > Show Package Contents, then navigate to the AppName.icns file shown in the pathname above.  Note:  After replacing the AppName.icns file one may need to run killall Finder in a Terminal to force the updated AppName.icns file to show properly everywhere.  If it's not showing properly in the Dock afterwards run killall Dock in a Terminal.

Another way is to paste an image into the App's Info Sheet after selecting its icon at the top left of the Info Sheet.  Select the application bundle then control-click (right-click) > Get Info or  ⌘ -I.

Or use a third-party app that can assign an new image/icon to the application bundle.
