Our application can load plugins that are written by users. Our application
has only had a 64-bit Macintosh version available for 366 days, so most of
these plugins are 32-bit. Therefore we also ship a 32-bit version of our
application so that users who have old plugins can still use our
application with their existing plugins. This has worked just fine with Qt
5.6 but as I reported compiling a 32-bit version of our application with Qt
5.9 isn't working the same way as with 5.6.

We plan to support only versions 10.10 and above of the OS, and obviously
only on machines with 64-bit processors. We are also aware of Apple's
announcements about abandoning support for 32-bit desktop applications in
future releases.

Thanks
