I'd like to change the icons on built in Mac apps such as Safari, Voicememos, Settings, etc. For 3rd party apps it works for me to go to "Get Info" and paste a new icon in, but this doesn't work for system apps.
I have tried disabling SIP and now instead of nothing happening it makes an error sound, but the new icon still doesn't show up. Macbook Pro, Ventura 13.2.1, Apple M1 Pro. Anything helps! Thank you.
