I am fighting with stuffit over a .sit file. I have version Stuffit version 8 installed but keep getting the error "Sorry, Expander requires Stuffit Engine 8.0.0 or later. Please reinstall...." It looks to me as if there are several versions of stuffit installed on this machine (was 10.2.7, just upgraded to 10.3). Specifically the stuffit engine in /disk0/System_Folder/Extensions/ looks to be 6.0. Is there any way to get rid of all the older stuffit stuff? or better yet can I unpack .sit files with tar?
