Henry JB, thanks for your consistency on this topic.
Pod Farm 2.5 was released in 2011. Since then, many users complained about lack of Mac VST 64 bit version.
I called support many times about it. Most of the times, techs weren't aware of the issue or mixed up between 64 AU Mac and 64 VST PC.
Everytime I always had confirmation that 64 bit VST OSX was not yet available but will be in the future. Last time was 2 years ago...
As mentioned by JB Henry - certainly because they had many frustrated user calls- it is now written on Pod Farm 2.5 product page that 64 bit VST OSX is not supported. Now it's clear.
