A Mac version of EDICT2 is generated daily and is available on the ftp site. A discussion occurred in 2019 on the Honyaku mailing list about the installation of Mac dictionaries. A very useful posting was made by Christopher Frederick, so I have included it below.
Anyway, once you've downloaded the Dictionary Development Kit, you should be able to generate a dictionary using the procedure documented at https://developer.apple.com/library/archive/documentation/UserExperience/Conceptual/DictionaryServicesProgGuide/prepare/prepare.html Though I still haven't tried it myself--and I expect that some of the file paths in the document will be out-of-date--this should at least point people in the right direction.
Hope this helps!
