After 10 years of continued work on Attachment Tamer and over a year of, admittedly, not being able to keep up with Apple's sped up release cycle and increasing technical difficulties of Mail plug-in development, I decided to find a better way forward for both my customers and myself.
I am preparing a solution for handling attachments in current and future OS X releases, that would be up to the standard set by previous Attachment Tamer releases, in a partnership with well-known Mac developers. As the holiday season has slowed us down, I am going announce the more details early in the new year.
Happy End of the Year,
I know not what this portends. Perhaps Adam is seeking to seeking a buyer for AT???
Such that it is, 'tis better news than I was expecting...
