Mac OS X Catalina (and later) not supported
KARMA Software for Mac OS X is not compatible with Catalina (10.15) and later. KARMA Software is based on the older 32-bit Carbon Mac framework, and Apple has removed all support for 32-bit starting with Catalina and moving forwards. Therefore, after 18 years of continuous support, Mojave (10.14) is the end of the line for this version of the software.
There is no option moving forwards for us other than a complete rewrite of the software from the ground up. While this is being looked into, we can make no guarantee that it will happen, and even if it does, it will take a year or more.
Fortunately, there is a simple solution for people who want to be able to run older software and still move to 10.15 Catalina (or later): VMWare Fusion (or Parallels, although we personally recommend Fusion).
VMWare Fusion allows you to create VMs (virtual machines) of earlier Mac OS versions and run them inside a window on your Mac. It's especially easy to create VMs of the more recent Mac OS's, since the license does not prohibit it.
So, for example, you can create a VM of Mac OS X 10.13 High Sierra or 10.14 Mojave (which will be able to run your older 32-bit Mac apps), and run it inside of 10.15 Catalina.
Alternately, you can use the Windows version, which presently remains compatible with XP through Windows 10 version 1909 (not compatible with Windows 10 version 2004).
We are sorry for any inconvenience and thank you for your support these many years.
