My mom Upgraded to the new Apple OS and found a great number of program not upgraded to support the new OS This may be the same with BorisFX Products as well.
We are not aware of any problems with macOS 10.14 when using the latest versions of Boris FX products. Mojave should be fully supported. If you are saying you are aware of problems, then please give more details. Otherwise your post contains no actionable information.
I’ve been working with Mojave for a while now, and there are no issues with any product in the BFX line up.
