If you share a single Mac with other users and you’d like to share your iTunes and iPhoto libraries with them as well, If Then Software has created ShareAlike to help you. The new software, released as “DonationWare,” can be downloaded from If Then Software’s Web site now.
Designed for use with Mac OS X v10.3 “Panther,” ShareAlike features a pop-up menu that allows you to specify which user accounts on your computer can access your iPhoto or iTunes libraries. ShareAlike then renames those users’ existing libraries to keep their own files safe; your libraries will then be readable and writeable to other users.
