This is my first post in this forum. I set out this morning to check on the status of a 64-bit Mac update, since I see a 64-bit Windows update is out. My two cents on this topic:

I use BIAB as a practice tool and for generating scratch tracks for arrangements I complete on my DAW. My last update was to BIAB 2017. The reality is that unless a 64-bit Mac version of BIAB is made available (and fairly soon) it will have to be left behind. The other software and devices I use force me to stay relatively up to date over time, and when 32-bit apps become unusable that will be the end for 32-bit BIAB. I may keep an old Mac around for awhile just for BIAB and a few other 32-bit apps, but I know better than to believe that will work for very long. Bottom line is that buying 32-bit BIAB updates no longer makes sense for me.

Here's hoping PG Music is working on a fabulous new 64-bit Mac version of BIAB!
