What is "macos ventura"?

Is it part of a larger Garritan library?

Can you load other Garritan sounds?

Have you changed computers recently?

MacOS 13 aka Ventura Is the latest version. Many apps are not yet compatible.

MakeMusic has promised that Finale 27.3 will be compatible with MacOS 13 but it has not been released yet. It will include a Ventura compatible version of the Aria Player. Again, neither of these have been released — yet.

Thank you very much for the information. I will look forward to the update.

The Finale 27.3 update was released today. So, go ahead, download it from your Account and install. Make sure that you run both installers in the download.

If you still have problems, use the Submit a request link at the top of the page to submit this to MakeMusic Support. Good luck and please let us know what happens.

Hello friend, from trying things and replacing files in system folders, I think something went wrong because it didn't work. So, I decided to format the disk and reinstall from a version of Time Machine. I installed Finale with the v27.3 update, then jazz big band 3 from garriran and it worked perfect. 

Thanks for your help and for your comments.
