The 64-bit version of Beyond Compare v4.3 for macOS is coming along well. There are still issues to fix, but it is usable on macOS 10.14 and the viewers, scripting, and reports all work.

We plan to have a beta out ASAP after the macOS 10.15 beta drops, and hope it will be before the end of WWDC (June 7th). We will have to test BC on 10.15 ourselves first, but will try to do that quickly. The schedule may slip if the new OS causes any issues that significantly affect usability/stability.

When it launches, we will announce it here, on Twitter and Facebook, and it will show up as an optional download in the "Check for Updates" dialog. There will be a page listing known issues.
