while playing around with KSTARS, I found two "unusual behaviors" in the Prefs regarding the "Apply" button:
Configure -> Catalogues -> Deep Sky Catalogue
Select or unselect an catalogue-> the "Apply" Button stays grayed out.
You can only press "OK".
Configure -> Satellites -> List of Satellites
Select one or more from the list -> the "Apply" Button stays grayed out.
You can only press "OK" or "Update TLEs".
This issue is still unresolved in version 3.5.2 (MacOS).
After pressing OK (as "apply" is greyed out) all changes are lost.
As you can see, I've just selected Intelsat, but I can't save this due missing apply button.
I could now select/un-select e.g. "Draw satellites as stars" to let the apply button appear and save my settings.
Beside of this behavior I can only see Satellites in KStars when I de-select "Show only visible satellites".

Looks this is a MacOS issue, on Linux the settings are reflected without needing to click "Apply". Just restart KStars to ensure everything is loaded again.
Looks like this issue still persists in 3.6.6 stable on MacOS.
Clear Skies,
