Increasing System Resource Limits on macOS 2019-09-07

To run OpenSim with more than one region in a OpenSim instance on macOS you might need to increase the max allowed files open and/or processes per logged in user.

Placing the two files in the zip file inside /Library/LaunchDaemons will set the maximum allowed open files to 65536 and maximum allowed processes per logged in user to 2048 at the system level on system startup.
