Given the fact that most apps are signed and won't run if the signatures don't match, and that macOS has had built-in user customisation of icons without tampering for many years, I think it's safe to assume it's using the latter.
- mh- 2y agoProbably? I've never customized icons on macOS. But this from their site made me curious: > Replacicon even watches for app updates in the background so your customized icons are not lost across app updates. edit: a quick google suggests this is just because some application updaters remove the old package entirely, so I guess it's what you said.
- danpalmer 2y agoYeah this is exactly it. When you delete and replace the app bundle macOS loses that customisation (understandably) and therefore you have to re-apply the customisation. This is why user customisation never works particularly well.
