From time to time I try, try again to run this software on my Mac -- and fail. I understand it involves having the *right* version of Java -- which may or may not be the *latest* version. There may be some talk about reverting to prior Java versions. I hear you also need to allow 3rd party software (I do). Helpful folks like @awasson have mentioned they can make it work, at least on fairly recent versions of the OS. FWIW I'm running Mojave, OS 10.14. Any help would be gratefully received. Thanks.
