Bob, we don't know for certain, but yes, the move by Apple is a good motivator. I mainly use the Windows version of BIAB, but I also have a Mac version of BIAB 2018 which, like BIAB 2018 was, is 32-bit only. The current OS on a Mac gives you a warning that at some point, 32-bit apps will no longer be supported.

We hope that PG Music is developing code that can easily be ported from the Windows 64-bit version to a Mac 64-bit version; such cross-platform development would make obvious sense. Whether that happens this year or later, it still will be a lot of work for PG Music to go to 64-bit on the Mac version. We also do not know if there will be a BIAB Plugin for the Mac version, and as you recall, much effort went into that for the Windows version and is still continuing.

The effect of these substantial program changes forced by the operating system on other reported issues, is not known by us users.
