I want to change the color of the badge icon from red to blue. I just upgraded to Big Sur. I used to be able to do this by booting into Recovery mode, running the command "csrutil disable" in Terminal, and rebooting. Then, go to System/Library/CoreServices/ right click on the Dock.app and hit show package contents /Contents/Resources/". Then I clicked Get Info, unlocked with my password, and added "backup" to the end of the filenames of statuslabel.png and statuslabel@2x.png files. Then I put my customized badge icon pngs with the original filenames in the folder. The reboot again in Recovery mode to enable csrutil, then reboot again. ---Now, when I get to the step of renaming the mac os filenames (statuslabel.png and statuslabel@2x.png) in Get Info, it won't let me, even though I unlocked the finder window and entered my password. This probably seems like a really minor thing, but I want notifications; I just don't want the color red in my face all day long. Thanks so much for any help you can give.
