Is Typinator compatible with macOS Ventura?

Yes, in general the current version 8.13 of Typinator runs on macOS Ventura.

We are in the process of preparing a maintenance release that irons out some small Ventura compatibility issues and will release a beta of Typinator 8.14 soon. We recommend turning on the "also check for beta versions" in Typinator Preferences -> Update, such that you will be informed as soon as we have released the beta.
