You don't state which version and build of Moneydance you are running. e.g. 2019.2(1868). What operating system is your new computer using.
I had read of issues with Linux but other users have reported that the latest preview build works well on other operating system. Maybe worth a try especially if you are in a position to reinstall your existing build if you find it does not help.
I found the culprit. I run FontExplorer Pro as my font manager and even though it disables Font Book in the OS it does nothing about several Font Book system caches and plists. I went to my favourite font management person for Mac (Kurt Lang http://www.jklstudios.com <http://www.jklstudios.com/> ) and followed his extensive advice about my system and its relation to other apps etc.
Moneydance all good now. Updated to latest version 2019.2
Thanks for help.
