Will 32 bit apps still work in Mojave?

Mojave supports 32bit apps. It's the last macOS that will.

It depends. Mojave support for 32 bit depends on the app. Some will work, others won't. I have about 8 apps I still use that don't have a 64 bit replacement yet. They all work for me in Mojave. They are also all smaller utility apps that have a better chance of working.

Using AccountEdge Pro this is 32 bit. Any idea if it will be OK in Mojave?

Just to add, an app may not be compatible with Mojave for reasons that have nothing to do with it being 32bit.

That too. 🙂
