Here is a version 1.6.5 for users on macOS 10.15.
Before downloading, make sure you delete the App Store version on your Mac.
- Drag the file to your Applications folder. You can run it from the Downloads folder, but you’ll probably want to override your existing app in the Applications folder.
- If you haven’t done this already make sure you’ve changed your security preferences or macOS will prompt you to change it.

3. Once you open the app you’ll want to log back into your Topo Maps+ account.
4. You will not be able to make purchases in this app. If you want or need to make a purchase do it on your iOS device and the purchase will sync to the Mac through your Topo Maps+
