When starting Hedge on a too new OS, you'll get a warning that you are using an unsupported OS. You can either chose to upgrade your license, or continue as is. We cannot guarantee it will work without issues, as especially Apple often changes core systems that affect data transfers. Use of non-supported Hedge versions is fine, but at your own risk, and obviously, not supported by us when you do run into an issue and reach out. We’ll of course try to help, but if your issue is obviously caused by using a too new OS, an upgrade is required.
