Agelong Tree family tree application runs on two platforms: Windows and macOS. This autumn there will appear a new macOS version 10.15 Catalina that doesn’t support 32-bit applications and it means that previous Agelong Tree won’t work on it. We have released a new 64-bit Agelong Tree build for macOS that will work on macOS 10.15 Catalina as well as on other macOS versions starting from 10.10. Download the new build, install on your Mac and stay with us!
