On previous versions of macOS, it was possible to change the Finder icon in /System/Library/CoreServices/Dock.app/Contents/Resources/.

However, this doesn't seem possible in Catalina anymore? Even with SIP disabled?


Based on this answer: Cannot change login wallpaper in 10.15 Catalina?

  1. Reboot Mac, holding R to boot into Recovery mode
  2. Open terminal
  3. Disable SIP with csrutil disable
  4. Reboot Mac
  5. Open a terminal
  6. sudo mount -uw /
  7. sudo cp ~/your-new-icon.png /System/Library/CoreServices/Dock.app/Contents/Resources/finder.png
  8. Repeat for finder@2x.png
  9. Reboot into recovery
  10. Re-enable SIP with csrutil enable

  • You should not need to disable SIP and do the reboot dance! Simply make the change while booted to the Recovery HD and note that the path will be e.g.: "/Volumes/Macintosh HD/System/.." – user3439894 Oct 8 '19 at 12:11
  • Interesting. Will definitely have to give that a go next time! – Alec Oct 8 '19 at 16:41
  • Just wanted to note that this method still works as of 10.15.7 – Colin Fredericks Oct 30 at 21:22
