Will they work with Mac Catalina?
Jaksta Media Recorder does work with Mac OS Catalina.
We have a new beta available that is more compatible than the current live release. You can get the installer for the beta here - https://download.shedworx.com/jaksta/beta/2.2.6_293/JakstaMediaRecorder.pkg
When you first attempt to run the installer you will receive a Mac OS notification saying that it can't be opened because it cannot be checked for malicious software. Click 'OK' and then go to System Preferences > Security & Privacy > General and click on 'Open Anyway' down the bottom. It will either run the installer or another similar notification as the first will appear and you just need to click 'Open' and then the installer will run.
