Thanks for the link, Rob.
I already had a shot in the past , but - sad to say - it's not for my level.
I'll keep being VERY satisfied with the dmg.

With KStars 3.3.3 I couldn't take bias, darks and flats

Here's my logs from tonight's testing. I seem to be able to take single images in the capture module and guide module. I can take as many single images as I want with no issues using either camera (ZWO ASI1600mm, or ZWO ASI120mm). But if I try to loop images in the guide module, the computer hangs (beach ball), and I can't access the app anymore, and am forced to force quit the application. The hang happens with both cameras. I rebooted between hangs, and the issue persists.

Logs attached.

I just saw JCJ's post above, and thought i would try to take flats, darks, and bias. I have the same issue, They don't take. Ekos reports an issue if you try to do a single frame. So I created a sequence for each, and tried again. The sequence doesn't start. It just sits on 0 frames and says waiting to capture.

Here's the log from that session.

Ok, that gives us a little more to work with. We can check it out tomorrow. Right now I am imaging the Lagoon, Trifid, and Swan in a big frame.

I reported the issue to Jasem and he is investigating. After I was done imaging my targets last night, I tried taking Darks and I confirmed that yes there is an issue with the dialogs Jasem has been working on. I wasn't prepared to test the guiding issue since I was doing wide field and didn't have a guider or guidescope with me.

I have built a new DMG yesterday and tested the version, I found three problems:

1 - Captured images are not displayed in the summary window (old problem I think), this is specific for MacOS, Linux Version Build: 2019-07-23T12:54:33Z is not affected.
2 - In the focuser module, the focus star is lost during autofocus, it seems it can not find it on the cropped square.
3 - Every time I start Kstars it looses my Geographic location (Lisbon, Portugal) and defaults to Greenwich UK.

I have no logs from it. I have to test again.

So we figured out the issues with the darks etc that Andrew and JCJ reported. It was just the order in which Jasem added the Yes/No buttons. Very strange because it works fine either way on Linux, but on MacOS, the order mattered.

Nmac, what is the problem with the summary window?? every image I take displays there. Is there a setting you have changed somewhere different than me? I haven't had the opportunity to test your #2 issue because I've been using a camera lens for my last few nights out, so no autofocus capability. #3 is very strange. The geographic location should get saved before KStars closes, have you had crashes that prevented it saving this information?

Well in my case the summary window simply does not display de captured image, and I verified, the option is turned on in the settings.
This also happens with simulators. I know this happened some time ago too. I can't figure out what's happening.

The geographic location issue, i have noticed, is random, sometimes it displays the correct location, some don't.
I will investigate this issue better and report. Tonight I will make another AF run to see what happens.

I don't know if it's relevant but I am build from sources on Mojave.

The geographic location is fixed for me in 3.3.3. It was previously not saving in 3.3.1.

I also build on Mojave for that matter

I have deleted KStars app and all config files and restarted all over with your DMG.
The only issue that still active is the first one (no image shown when capturing). All others solved, so something went wrong with my DMG.
You can see my options attached. I am in the middle of a session, as soon as it captures one image i will put a screenshot here. EDIT: Added.
