“GoldenDict“ is a dictionary lookup program which supports Linux, Windows and Mac. You can download the program for Mac “here“.

To make it work, you need some dictionary files as well. For example, this project provides some dictionary files for Chinese.

After install the program, go to “Edit -> Dictionaries -> Sources -> Files”, add the path which contains the dictionary files and check the “Recursive” option, then click the “Rescan now” button. If everything works, the program will import the dictionary files and you’re good to go.
