Same here, Chart installer has been a trauma since the beginning, I try to update as less a possible, most of the time It kills the card and I need to send it back to the marine shop, they fix it and the next try... broken again.
also on MacOS it is impossible to select the whole card so I have to select the area on a box, with is smaller than the cart.
Support takes weeks to respond ad is no real help, BIG BUMMER, I will buy C-MAP next time, do NOT buy Navatics if you use Apple Mac.
Absolute impossible to install on MacOS 10.15.5
