Hey All,
Here’s a quick link to Erik Mendoza’s Interpres, which works to bridge the gap between Whitaker’s WORDS and the latest editions of Macintosh OS X.
When I finally purchased a new laptop, I discovered that Whitaker’s WORDS was no longer compatible with Macintosh Mountain Lion (OS X 10.8). William Whitaker died recently so his version of the software remains static and incompatible with the latest versions of OS X. However, Erik Mendoza has been awesome enough to produce Interpres, which is a compatible (and I would argue more user-friendly) version of the WORDS program. Hopefully, Interpres will also jive well with Apple’s up-and-coming Mavericks (OS X 10.9), due out later this year.
If anyone wants to add a footnote about the latest version of WORDS for Windows 8, I’m sure it would be well received! For those of you suffering under the heel of Windows 8, I offer my sincere condolences.
Cheers,
Ryan

LatinEdit – http://www.cinder.hk/LatinEdit/Overview.html – is a far superior implementation of Whitaker’s WORDS… or rather: it was, because I don’t think it’s compatible with 10.7+. LatinEdit has (had) conjugation & declension tables etc., more than just a dictionary. Nice little app.
If it’s incompatible, a solution would be to install Virtual Box – https://www.virtualbox.org/ (it’s free) – and launch a Snow-Leopard-(Server)-plus-Rosetta emulation within a newer MacOS to run these older apps.
Awesome, thanks!
PS: the links to the Mac version of the Latin Words dictionary (r4, v1.97e) seem to be offline. You can still download it at cnet: http://download.cnet.com/Latin-WORDS/3000-2279_4-10741069.html
Yet another update, namely the 10.7+ compatible build of Whitaker’s dictionary to go with the latest Interpres build (and all other compatible GUI wrappers running on 10.7 or later).

Just to clarify, this is already included in the latest Interpres (which you’ll discover if you follow the link).
There’s also http://www.u.arizona.edu/~aversa/latin.dmg which is not as informative but super fast to use with the three-finger-tap.
