I get a warning that KaleidaGraph is not optimized for my Mac. Will there be a 64-bit version of the software?
Yes. We are currently rewriting the software for a new development platform which will allow us to provide a 64-bit version of KaleidaGraph for both Mac and Windows. Beta testing for the 64-bit Mac version is currently underway, however it is too early to predict the release date for the final version. Registered users who are interested in beta testing can complete the form under the Support menu of our site.
If you do not want to use a beta version, we suggest using a program like VMWare Fusion, Parallels, or VirtualBox to install and run an earlier version of the OS as a virtual system. If you have multiple Macs, you could leave one at an older OS. If you have access to a Windows computer, the Windows version of KaleidaGraph can open your Mac files. Here are links to setting this up using Parallels Lite and VirtualBox: Parallels Lite: https://www.imore.com/how-install-macos-vm-run-your-32-bit-apps VirtualBox: https://appletoolbox.com/need-to-run-32-bit-apps-on-macos-catalina-use-a-mojave-virtual-machine/
