There are different versions depending upon the version of MacOSthat you are running:

For macOS versions prior to High Sierra:

https://www.dropbox.com/s/2ml28l9a9iv0dzt/SkyDemon%20for%20Mac%203.7.1.zip?dl=0

For High Sierra:

https://www.dropbox.com/s/nr3rv8dxp9vdfx8/SkyDemon%20for%20Mac%203.10.0.0.zip?dl=0

Download this, uncompress it, then copy it to your Applications folder.

If you've already got an earlier version installed, first dragit from Applications folder to the Trash - you shouldn't lose anysettings when doing this, as these are stored separately in your Documentsfolder.

Important: The first time you run it, youwill need to locate it in the Applications folder from Finderand press the Control key, then click the app icon, then choose Open from theshortcut menu (this is because it is 'untrusted' - see: https://support.apple.com/kb/PH18657?locale=en_US . You may also have to click “Allow” to a pop-up about accepting inboundconnections.

When you first run SkyDemon it will check to see if a morerecent version is available, and if so will prompt you to download and installit.

Please use this thread for any specific feedback / issues withthis build (good or bad) - keep complaints about lack of native versionelsewhere. I can’t promise to fix everything - and indeed one day this mightall suddenly stop working when some unwanted update comes along. At the risk ofsounding like a lawyer, use entirely at your own risk.

Known issues:

As with the previous versions for Mac, there is now oneknown unresolved issue:

 - you must have a printer installed and configured beforeusing Print Centre, otherwise Print Centre won't work;

How does it work?: 

This uses a technology for wrapping Windows apps to run on macOScalled Wineskin, and should run on macOS 10.6 and above. It wraps SkyDemon forWindows.

Hi again,
‌and sorry for the late reply. I don't come here everyday. ‌Thank you for your reply rikur.
‌
‌I've booted the my system several times before I referred to this forum, though it didn't help. ‌I just tried to find the folder described above, but couldn't find it on my system...? $HOME/Library/Application Support/Divelements Limited/SkyDemon Plan .. the bold folders do not exist in my case.
‌At present, my startup freezes directly after the message, that I need to download any charts first. I see the checkboxes, but cannot select any.
‌
‌Any more ideas?
‌Regards
‌Lars

Have you got a $HOME/Documents/SkyDemon/ folder? If so, is it empty?
‌I've seen it hang at that point when it's unable to create this for some reason.

Grasping at straws, try cleaning things up, from a terminal prompt:
‌rm -rf $HOME/Documents/SkyDemon
r‌m -rf "$HOME/Library/Application Support/Divelements Limited/"
