Change the package icon created by the package manufacturer

Question

I created a package file (.pkg) using packagemaker ver 3.0.4. Is it possible to provide a custom icon in a .pkg file. Can someone help me how to do this? Thanks in advance.

Answer 1

Similarly, you set the custom icon of any other file, folder, or package.

Answer 2

Setting an icon for an mpkg, works fine

# create a file that actually going to set the icon file
touch <package_name>.mpkg/Icon$'\r'

# --- copy the customIcon.icns file to the <package_name>.mpkg before doing the sips, if its needed you 
# can take a copy of the file before doing the sips command, doing on a copied file will do good


sips -i <package_name>.mpkg/customIcon.icns
DeRez -only icns <package_name>.mpkg/customIcon.icns > tmpIcon.rsrc
Rez -append tmpIcon.rsrc -o $'<package_name>.mpkg/Icon\r'
SetFile -a C <package_name>.mpkg


# removing the tmp file
rm tmpIcon.rsrc

# remove the .icns from mpkg                
rm <package_name>.mpkg/customIcon.icns

# if you want you can hide the Icon$'\r' file inside the .mpkg file, file that presently sets the icon 
SetFile -a V <package_name>.mpkg/Icon$'\r'


Hope this helps.
