astap program / Forum / General discussions ASTAP: Astap and macos M processor

Mariusz - 2025-03-04

I bought a new MacBook with an M4 Pro processor. When trying to install Astap, the system prompts me to install Rosetta. Isn’t this a native application for Apple Silicon? I tried the latest M1 version as well as an older M1 version. Both also asked for Rosetta. Why?

Can someone help?

Hi Mariusz,

Have you codesign the program? See below

Han

MacOS 64 bit version (Apple silicon processor, M-types cpu). Code signing of the executable is required. Instructions:

1) Download
https://sourceforge.net/projects/astap-program/files/macOS%20installer/astap_M1.pkg/download

2) Make sure the ASTAP program is not running. Place the mouse cursor on the pkg file and install using the right mouse button popup menu.

3) Open a terminal windows and copy paste and execute the following command:
codesign --force -s - /Applications/ASTAP.app/Contents/MacOS/astap

The code signing is required only once. An update doesn't require code signing.

Yes I have done everything as above and still program ask to install Rosetta first. I installed it on another MacBook with an old M1 processor with allready Rosetta installed, and here’s the situation:
The program installed successfully, and I checked in the Activity Monitor—it’s indeed running natively in Apple mode. Maybe it’s just the installer that requires Rosetta?

This is new for me. I have only an old Mac with an Intel processor, so I can not test it. The installer PKG file is only a compressed package but yes maybe there is somewhere a flag indicating Intel.

I will investigate further but not have a solution yet. Is installing Rosetta 2 a major step you want to avoid?

I assume I know the cause. There are two other command-line programs included in the package which do not run natively using an M processor.

unprocessed_raw : this one is used to convert dslr raw to fits.
fpack & funpack: there are used for un/compression of fits files.

I assume if I upgrade these command-line programs the pkg installer will work. Compiling unprocessed_raw for the M processor should be doable. The ohers fpack/unpack I could leave out of the package..

This link is quite complicated for me. Is there a chance for an installation package without Rosetta?

If you do not have DSLR images, I could just remove the intel programs and it will work for you. I will make such a package.....

Try this striped version:

Tell me if this works for you.

After installing you also have to codesign it

YES!!!! Now its working perfectly! Thank you very very much! Nice job!
After coding, I received the following feedback:
/Applications/ASTAP.app/Contents/MacOS/astap: replacing existing signature
/Applications/ASTAP.app/Contents/MacOS/astap: resource fork, Finder information, or similar detritus not allowed

Is this ok?

Program is working ok but I get an error every time I close the application:
The ASTAP application unexpectedly crashed.

The cause of the crash is unclear to me. I need an Mac with an M processor to test the program in the compiler& debugger to find the cause. I need a volunteer to allow me to remote login in his Mac and install the compiler & debugger and run the program to trace the cause of the error. Taking maybe 2 hours

Does the crash also happen in the older M1 Mac?

I put a link on my webpage page to this ASTAP stripped version. More users will have the same problem.

Yes, this error also occurs on M1 when close app.

I see the same error on my Mac with an intel processor. Okay I will fix it....

Great support. Thank you very much!

The error is fixed. I have also compiled the DSLR conversion program for M processors. Can you test it for me?

Download & install the ASTAP for M processors:

https://sourceforge.net/projects/astap-program/files/macOS%20installer/astap_M1.pkg/download

Try to load a DSLR image in ASTAP . If you do not have one try this CR2 image:

OK, I have tested:
1. The program installs correctly without Rosetta - OK
2. The program closes properly without crash - OK
3. The program loads an image from a link - OK

Is there anything else I can do for you?

I have only one sugestion. In stack menu then I click brows to add fits files keyboard shortcut "cmnd A" to select all is not working. Also then I view list of files shortcut to rename "cmnd backspace" also not working. Is this normal?

Good news. Thanks for the feedback.

About the keyboard commands. I do not know at this moment. Often these commands are programmed with CTRL instead CMND. My source can be compiled to Windows, Linux and Mac. I will check the new weeks. First some other things to do here.

Cheers, Han

Please upgrade to ASTAP version 2025.03.07. The previous version has a bug in sigma clip stacking of OSC images.

Cheers, Han

Astap version from this link:
https://sourceforge.net/projects/astap-program/files/macOS%20installer/
need Rosetta again :(

No should be fully M processor unless i made a mistake. So no Rosetta required.

Something must have gone wrong. Unfortunately, it’s calling for Rosette now when I wanna start instalation.

I think it is all fixed now in version 2025.03.11. Can you check?

1) The threads where running on a single processor because the number of available CPU detection's did not work for MacOS.
2) I did by mistake put the X86_64 version in the M package.
