Opening Mac fonts in Downloaded Stuffit Files
If you are having trouble accessing Mac fonts in downloaded Stuffit files (files with a sit file extension), it is because the newer Mac OS doesn’t have a helper application for the browser for older sit files. You can download and install the free Stuffit Expander (http://my.smithmicro.com/mac/stuffit/expander.html). After you download a Mac font (a sit file), first navigate to the folder where the sit file is. Hold down the Control key and click the file. In the context menu, choose Open With > Stuffit Expander. That will expand the sit file and give you access to the actual fonts.
