Installing Orinj on MacOS is simple – download the orinj.zip file from this site and unzip it (it may already be unzipped by the download). Double-clicking on orinj.jar to start Orinj, however, produces the message "orinj.jar cannot be opened because it is from an unidentified developer". You can close the message by clicking on the Close button, but you cannot start Orinj.
To open Orinj, follow these steps.
- Close the message, if it is still open.
- Right-click on orinj.jar and choose Open from the popup menu.
- You will see the same message, but with two buttons - Open and Cancel. Choose Open.
- Orinj will open.
You will have to do this only once. Double-clicking on orinj.jar will open Orinj after that.
