There is no native version of the software that will run on a Apple Mac. I don’t have the time or resources to look into this possibility.
However, it is possible to run the software if you are prepared to follow the steps outlined below. This example is for Meeting Schedule Assistant.
Step 1 – Install Parallels Desktop for Mac from:
Parallels Desktop is free for 14 days and you can test before purchase it.
Step 2 – Install Meeting Schedule Assistant by double-clicking the executable:
Step 3 – Once installed, double click on application icon.
The latest version of Parallels (as of October 2019) is 15. This information and screen shots have been kindly provided by @stecchio. Thanks!
I don’t know how easy it is to run the Public Talks software on the Apple Mac but I assume it is the same process.
Last MacOS Catalina accept only 64 bit only but you can install 32 bit apps inside Parallels because Windows is run as virtual machine.
