Group automation on Mac doesn't copy.

Do you have “automation follows events” enabled? Edit -> Automation Follows Events.

Without seeing a screen shot some other things could be locked or frozen tracks and incorrect selection with the range tool.

As far as I know you are wrong.

To copy everything including group and bus automation data you have to use the global copy command to achieve what you want. And it has been this way as long as I can remember.
Groups automation do not follow when moving or copy/paste events and for a good reason.

But yes, it would be nice to have the option to select a range with the range tool and select th tracks to copy and get the group to follow suit, but it won’t do that.
