2026-10-09 APP 2.0.0-beta48 has been released !
This is mainly a bug fix release for the reported bugs in beta47. In addition it has a significant User Interface performance improvement noticable when you need to process 1000s of images in APP.
2026-10-03 APP 2.0.0-beta47 has been released !
This is a very big release... many code optimizations/rewrites, many parts of APP are much faster and more precise, especially star analysis and registration are much faster ! Big mosaics will go much faster 🙂
And we introduce a new preview filter, which includes the new Adaptive Deep Sky Stretch and a General Levels Stretch, this has been long over due. The old preview filter (the panel on the right side to stretch and preview your data) has not been updated for a couple of years and it is a critical part of any APP session.
Adaptive Deep Sky Stretch or ADSS is a much more intuitive stretch algorithm. It is also color preserving (which is a great new addition in itself ! ) which means that the highlights are no longer bleached, color is maintained from the linear data while stretching. You can simply stretch your data using the sky background level and signal width sliders which work much easier and more intuitive. You no longer need to fiddle with the old complicated sliders with zoom buttons. All the zoom buttons for the sliders are made redundant. And you can enter slider values in the slider value fields yourself. I will make a youtube video in the coming days to explain and fully introduce ADSS. Once the video is ready, it will be highlighted on the forum.
RGB Combine upgrade !. The RGB Combine Tool has been rewritten mostly. The tool is faster and easier to use and most importantly, the Luminance slider to inject a luminance channel or channels into the RGB composite is now working correctly. It no longer bleaches the RGB colors. Combined with the new ADSS preview, you will get much better and easier great composites with great color! I will also explain this in a new youtube video.
mac os has been updated to sequoia 15.7.7 and uninstall and install app many times
Dear Jeremy jeremychou,
Thank you very much for sharing your issue.
Did APP work correctly before the update of macOS?
Which APP version are you using or trying to install?
Please try 2.0.0-beta45 from the downloads page: https://www.astropixelprocessor.com/downloads/
If that does not work, can you try 2.0.0-beta39 for example?
If that also does not work, the issue can be caused the macOS update possibly. (It would not be the first time that a macOS release has some bugs)
Can you run APP in the following way to see if we can collect a startup error log that might indicate the issue:
open -a /Applications/AstroPixelProcessor.app --stdout log.txt --stderr log.txt
Please run APP and close the process if it does not close by itself. Then share the contents of the log.txt file. It will be best to run this command from your documents folder for instance, then the log.txt file is created there.
Thanks,
Mabula
Hi @jeremychou,
Okay, thank you very much for your feedback.
Did you try beta39? Did that not work? Beta7 is quite inferior to the latest beta's, so we need to have this work with beta45 as soon as possible.
Did you try to record the error log?
Mabula
beat39 is not working either

Hi Jeremy Chou @jeremychou,
I looks like a problem with having different APP versions installed into the same folder somehow.
Please remove APP completely. Make sure that the folder :
/Applications/AstroPixelProcessor.app
does not exist, before re-installing APP.
Please try beta39, if that works, simply try beta45. Again, first remove the old APP version before installing the newer one.
The reason that I mention installation of different versions into the same folder is because of the error/warning that you get:
Jun 09, 2026 4:53:30 PM com.sun.javafx.application.PlatformImpl startup
警告: Unsupported JavaFX configuration: classes were loaded from 'unnamed module @636be97c'
Can not be produced by beta37 or later actually, The last APP version that would normally produce this warning is beta36.
So for some reason, APP is not started correctly due to having different APP versions in the same folder I suspect.
Please let me know if this solves it or not.
Mabula
