Update on the 2.0.0 release & the full manual
We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.
Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.
I'm having a hard time finding my stacked/registered image. I've managed to load the frames, set the "save directory" to a folder on my desktop, registered them, then APP makes the "gong" sound but no image shows in APP or is saved to the folder I set the save directory to. Where is the stacked/registered image? I've looked through a few tutorials but I think this question is so basic no one covers it. Thx for your help.

Did you have a reason to save your registered frames ? In a simple integration these are not normally saved. They sort of exist 'virtually' and go into normalise that way. If you do have a reason to save the registered frames then you should start the registration, then when it is complete scroll down to the bottom of tab 4 and hit 'save registered frames'.
This can be used, for example, to register results of previous integrations to each other so that they can be combined later.
It is perfectly feasible to load up the lights and calibration frames in tab 1, then go to tab six (check that the multi channel / multi filter options are right) and just hit integrate. APP will run all the steps/tabs and put the final integration into your working folder (unless there is a critical error).
However, I would recommend that you load the data and then go straight to tab 5. Run normalise and then check the graphs and see if there are any bad frames (clouds or whatever) that you would like to delete. Then go to tab 6 and run 'integrate'.
If I have misunderstood your question, and you have run a successful integration but can't find the output file, then that might indicate a problem with your setup. Some sort of permissions or access issue.

@connor231 Thanks for there reply John. What you described at the bottom is the issue. I have run a successful integration but cannot locate the output file.
I figured it out. Your reply pointed me in the right direction. Thanks you so much.Â
Ok - sorry about that.
You may need some help from someone familiar with the Mac setup. That's not me - I'm a Windows / Linux guy.
I would note that it looks like you are still using beta 41. I recall there were some reliability issues with that release. I would update to beta 45 and try again.
(edit - while I was typing this I see you have solved the problem).

Hi Jay @atlantic-city,
Thank you very much for sharing your question on the APP forum, welcome !
Is everything okay now? Or do you need more assistance?
Like John @connor231 indicates, please update to beta45 (beta46 is coming soon as well). You can always download the latest version from the downloads page:

On macOS, it is not recommended to save to your desktop, but if you try to do so, macOS should actually ask you if you approve this. Maybe that message from macOS was lost or not visisble at the time of your initial integration?
Mabula.
@mabula-admin Yes, thank you. I figured out what I was doing wrong. So it was no fault of the software... just my being a luddite and trying to learn too many user interfaces (APP, Premire Pro, LRTimelapse) all at once and getting confused. Thanks again for checking in!
