What utility or tool that runs which under Mac OS X 10.6 can I use to extract data (icon images and strings, etc.) from old Mac OS 7 (and earlier) resource files/resource forks? (...files created using ResEdit.)


Rezycle might work for you. Let us know.


Abet slightly unstable, the resource editor Rezilla runs under 10.7.4.


On OSX you can access the raw resource fork of a file like this:

cp resource_file/..namedfork/rsrc  resource_fork

There's also the system utilities DeRez/Rez (available in OSX 10.7 and some other versions) which allows for extraction of resource fork data into a form for use by the Rez resource compiler - e.g. extract icon data from an Icon file:

DeRez -only icns Icon^M > icon

It should be noted that the resulting files from both of the above commands require additional processing to convert the resources to a suitable form.
