I just copy the cm93 folder from one place to another. Cm93 is data in this instance,for O
to use. "Show" O
the copied folder.. Do you know the file system of your mac well enough to copy something over and then guide O
to that place?
If you have the cm93 on a cd or usb stick, copy the cm93 folder to the location suggested in the help link "the users home directory" or anyplace you understand . Perhaps where you are wont to keep pictures will do for now.
I don't get the "install" reference. It worries me, as being unnecessarily complicated and boggling in this instance. "Install" is roughly what you are doing when Opencpn finds them but "LOAD" is a better way to look at it for Data, I think.
I'm of the opinion that Apple is a bigger monkey to wrangle than widows when you get outside it's comfort zone (Itunes being it,as far as I can tell
), but I have managed to move data back and forth, and then look at it on an apple machine.
