I'm afraid, You're out of luck
There is a Bento-section in the forums - but there might be no desired answer as well..
I personally was never happy with bento because of the missing integration with FileMaker Pro. The integration into OSX (AddressBook, etc) was cool - but could no longer be done with newer releases, AFAIK.
Converting bento data into other DB's was (and still is) a nightmare (related data, photos, bento-lists, etc), integrating the photo-lib into bento duplicates the images, etc. As bento appeared, it seem to be very cool - but somehow it was not possible to maintain. R.I.P.
You might try to find a FM11 (or newer) version on ebay (don't get any older version!) - but since FM11 isn't officially supported anymore (it runs quite well on current OSX), chances are good, that You'll find Yourself at the same point next year or so. And converting Your bento sources will need work..
It's a pitty for bento users without budget )-:
Just realized that there is no longer a 'bento' - section in the forums. Sorry for mention this in the post before
Thank you for the post.
Support for Bento is through the Bento Forum archive:
For a full list of operating systems tested for Bento 4 review the following knowledge base article:
Although support for Bento 4 has ceased, I have Bento 4.1.2 running on my Mac OS X 10.9.4 machine. If you are not running Bento 4.1.2, then download it directly from Knowledge Base Article #11182:
Once installed, launch Bento 4.1.2. Does this work? If not, what is the error message you are receiving? Or, what symptoms are you experiencing?
