kstars on macOS has no 'bundle identifier' look at the Info.plist file: <key>CFBundleIdentifier</key> <string></string> note that all apps on macOS should have a valid bundle identifier. if you don't have one several things like caching and native preferences are broken.

thank you but this is *not* resolved in version 3.5.5. see the screenshot attached above - the bundle identifier is still empty. please re-open this issue.
still unsolved in 3.6.9
Should be fixed in 3.7.1
