A new version of MacOs (Catalina) is released.
For MacSign users:
MacSign Cut does not support MacOS 10.15 Catalina yet.
The estimated release date of the new MacSign version supporting Catalina is the first quarter of 2020.
Do not update your MacOs system when you use MacSign Cut !
When you by accident did already update your MacOS than you will need to revert this.
The current versions of MacSign’s plug-ins and Summa plug-ins for Adobe Illustrator are signed and work fine on MacOS 10.15 Catalina.
