uh oh numbers dont add up

Hi TYiangou, 

Welcome to the Community Forum. 

At present, MYOB Business is compatible with Mac OS 10.12. Unfortunately, versions of Mac OS 10.15.x “Catalina" or newer are not supported. This was also discussed in a previous post in 2022, which you can find here:  https://community.myob.com/t5/MYOB-Business-Getting-Started/Business-Lite-on-a-desktop-Mac/td-p/760031.

To use MYOB Business, you may need to access it from a device running a compatible operating system.

Please let us know if you need further assistance.
