    This has nothing to do with it being on a MAC or anything associated with your Mac. They are mutually exclusive as you have found out.

    • It would be good to know what exactly happens when you say, it won't tune. What message do you get? Make sure your tune power is at least 20 watts.
    • What is the antenna you are using - tell us more
    • Does it tune into a dummy load?
    • If it is an EFHW, do you have any chokes on the feedline at least 1/4 wave away from the antenna from your lowest operating frequency? This prevents RF from feeding back into the tuner and affecting SWR readings.

    Problem solved, performed a client ID reset per Marcus. All good now!

    Have I mentioned lately how impressed I am with Marcus software and support?

    Must be the best "Radio" software/customer support I've ever seen.

    Thank you for the comments,
