Testing OpenSim on macOS 10.15 Catalina today it was found that it fails to start with unsigned dylibs. There is no way to persuade the system to run these unsigned libraries as there is with an unsigned application.

I have signed the 4 libraries in question with my Apple developer ID, which after replacing the original ones will let you run OpenSim on Catalina.
They have only been tested on OpenSim 0.9.1 with mono 6.4.x so make sure to make a backup of your original installation before using them.

A zipped version will be posted in Resources. In the Finder you should be able to drag the bin folder in the zip into the same location as the bin of your OpenSim installation and the Finder should offer to merge the two. If not proceed to do a manual replacement of the singed libraries into the same folder location as your original bin.

These signed libraries have also been committed to the OpenSim 0.9.1 dev repository and will be included in a future release of openSim.
