I hate default icons but it's been a struggle to change them to some custom ones properly in El Capitan. DOWNLOADED APPS Sure, I can change icons for apps that I've downloaded the old way: Open the 'info' tab of the app and copy/paste the new icon onto it. But the change doesn't last. This morning, Tweetbot, for instance, went back to it's old icon all by itself. It happens every time an app updates through App Store. Then I have to manually change it to my custom icon once more. Is there anything that can be done about that? STOCK APPS (and Finder + Dashboard) Once upon a time, I could change icons on Safari, Finder etc. by using CandyBar but that doesn't work anymore and I can't use the copy/paste method for these system apps/whatever they are. Or can I?
