Catalina - Mac OS 10.15 - no longer supports 32bit applications. It is recommended not to upgrade to Catalina if a user has required applications that are 32bit.
The Mediasite Desktop Recorder (MDR) is currently a 32bit application and therefore it is not supported by Catalina. If you are already a Mediasite user, we recommend against upgrading to Mac OS 10.15. If you are a new Mediasite user already on Mac OS 10.15, you will be unable to install the MDR.
Attempting to install the MDR on a Mac using Catalina/OS 10.15 will result in an error that the OS cannot verify the application and check it for malicious software.
Attempting to upgrade to Catalina if the MDR is already installed will present the user with a dialog stating that the app is not optimized and will need to be upgraded after the installation of Catalina. At this time, there is no upgrade for the MDR available.
Please see the Sonic Foundry KB000004074 Knowledge Base article for detailed information regarding this issue.
You do not need to have the MDR installed in order to use Mediasite. You can create a recording using other software (such as the natively available Quicktime) on the Mac and then upload the file to your MyMediasite portal.
