I Use Big Sur 12.3.1 and Express 7.12.
Mounting the XT is no problem but as soon as I try to install the maps on the Mac it goes wrong.
The "install on computer" button is so small in height that it doesn't respond when you click on it.
Who knows a trick to get the maps installed on the Mac?
I tried using resolution 2550 x 1440 and 1920 x 1080, however it does not resove the issue..
