Created with Apple's new Icon Composer application, using SVG shapes extracted from emacs.svg image included in Emacs' sources.
A series of *.icns files are provided for macOS 15 and earlier, and a
Assets.car file is provided for macOS 26 and later.
Grab the .icns file you prefer from the Resources directory, and replace
Contents/Resources/Emacs.icns within your Emacs.app.
It may take a while for macOS to realize the change, you can try and speed it by temporarily renaming the Emacs app to something else and then back again.
On macOS 26, the icons support light/dark mode, clear glass mode, and custom
color tints as well. However, this works a bit different from the old .icns
files on earlier macOS versions.
Grab the Assets.car file from the Resources directory, and place it into
Contents/Resources within your Emacs.app.
Then edit Contents/Info.plist, and add/update the following:
<key>CFBundleIconName</key>
<string>EmacsLG1</string>Set the value to one of EmacsLG1, EmacsLG2, or EmacsLG3 depending on which
icon you want to use. All three are bundled into the Assets.car file.
The existing Contents/Resources/Emacs.icns file with Emacs' default icon can
be left alone. Or you can replace it with one of the EmacsLG*.icns files from
the Resources directory to change the icon for pre-Tahoe macOS versions as
well.
EmacsLG1 simplifies and changes the outer shape of the default icon to comply with the shape of Liquid Glass icons.
EmacsLG2 stays as close to the original round icon as possible, while giving it that Liquid Glass flair.
EmacsLG3 is the biggest divergence from Emacs' default icon, and is inspired by the changes Apple has made to some of its own icons in macOS 26.
