I have been following this thread and have downloaded and installed Kstars on my MBA via this dmg file. I don't have my scope and mount fully functional yet so cannot test all the functionality, but can confirm that the program appears to install and work. Only issue I had was with "setup", which I clicked wrong box and lost, but that s a user/kstars issue.
I'll be watching for any updates and as soon as my scope is up and running will test the other features.
