I am using MacLoggerDX3.9.8.with a Dual G-5 and Icom 756. Both the program and the support have surpased all my needs and expectations. This is a very intuitive program , so no need to be going back to manual much. Don Agro the owner is quick to answer any questions and any problems one might encounter.
Version upgrades are free within a reasonable amount of time(not sure exactly , but I have purchsed only one or two upgrades in the last few years (while I have downloadeed many version upgrades in the same time period.FYI -my pal at a large ham radio store tells me he is seeing many hams moving over to macs these days.
So try it out and purchase with confidence that you are really getting a great value. We Mac people are really lucky to have a guy like Don Agro programming for our needs.Regards to all. KG4USN
