You should now have a build that is accesible through the beta options that should help remedy the launch issue until we can get in contact with Apple and get a new build submitted.
To access this build follow the below;
Go to Library.
Right click on Talisman.
Go to Properties.
Go to Betas.
Select macfix from the drop down box.
This will be a temporary build, as said, until we can update OSX officially but this build will get Talisman working for you over the holiday period and it won't affect your ability to play cross platform, so if you've got buddies that play with you from Android, iOS or PC then you should still be able to play with them.
We apologise for the inconvenience but we have got this temporary fix tested, confirmed and up and running and there will be a more permanent solution with you shortly.
