First off, apologies if this isn't in the proper section. I've found the process of getting a City Navigator map downloaded so unbelievably frustrating and can't find a workable solution. I'm on a Macbook Pro with completely updated OS.
I go to my.garmin, log in, see the map I purchased (and my Montana 680t is connected and visible to the computer), and when I click "Add To Device," it just sends me to a mostly blank page in Safari. I tried the support solutions for the Garmin Communicator plug-in to no avail. I've read Garmin comments on Twitter saying they will not be updating the plug-in and Safari itself warns it is a dangerous one and not supported any longer.
So how in the world do I gain access to the map I purchased? Any working help would be greatly appreciated!
