  1. I am unsure of how to remove or delete the file /Library/Java/Extension/RXTXcomm.jar
    I have typed this in the terminal but it was unable to find it. I am sorry but I am not very computer literate. Where do I find this file, and how do I delete it?
    You will have to give me pretty explicit directions step by step if you could.
    Sorry but I am just a dumb blond

    1. Hi, I’m sorry but in the meanwhile i switched to Debian on all my systems, for this reason I’m not able to check for the file location. I suggest you to use the utility “locate” which should be present in osx. so if you type in a terminal “locate RXTXcomm.jar” it will output all locations matching that name (or as part f the name). I hope this will point you to the right direction. Let me know.
