Macintosh Acrobat plug-ins need to be modified in order to support Adobe Acrobat 7
JANUARY 5, 2005 — Current Macintosh versions of Adobe Acrobat plug-in software
will not work with Adobe Acrobat 7.
According to Lori DeFurio, Adobe's Developer Evangelist, the reason is:
"Apple Computer has strongly recommended that all product development
be done under Mach-O, instead of the older, deprecated PEF platform.
As a result, and because continuing to support PEF means that
Adobe would have to write substantial bridge code, Adobe has
opted to move Acrobat to a fully compliant Mach-O application.
This issue is being discussed extensively amongst developers of
Macintosh Acrobat plug-ins, and mainstream plug-in developers
are working on plans to make the required modifications to
their plug-in software as soon as possible.
"This allows [Adobe's] developers and customers a forward-looking
perspective on the technology, allowing plug-ins to have maximum
compatibility with future versions of the Apple OS X."
