Siril ver 1.2.5 will not load on my iMac 4 Sequoia 15.2

I installed Siril ver 1.2.5 on my new iMac M4 Mac OS Sequoia 15.2 .I was able to bring up the complete program once, Now it will not load. When I click on the Siril app: “Siril” appears at top right of tool bar , a pull down menu that contains About, Settings, Services, Hide Siril,Hide Others, Quit Siril. No other options

Do you use multiple screen?

Because on my side, no problem on macOS. And following on what you say, this is because Siril is loaded, but not in your main screen.

No that is not the reason, Siril is in my toolbar and when I select it by clicking on the application it will not load. I have tried closing Siril, removing it from the tool bar and restarting computer. Selecting Siril from the available applications it still fails to load completely.

I have also tried uninstalling Siril and downloading a fresh copy and reinstalling. Sirl will work as expected after a the install as I was able to process a few light frames. Then It will crash and not completely load.

Is this Siril from Homebrew? Or from our official package.

Well. I’m not enough of a macOS expert to understand. What I can say is that the application works on every Mac I’ve tried. And from what you tell me, Siril still starts, except that you don’t see it.
You should try deleting the config.ini file to see.

Siril did work on my old Mac with an intel processor. The problem is on my new Mac with the Apple M 4 processor. This computer went on sale in November.

Siril works well on every Mx processors.
I think there is an issue on your side. As I said, Siril is started. You should try to do what I said.

There are no config.ini files on a MAC that is a Windows file. However all I can say Siril worked fine on my old Mac with Intel chip and is not working on this new Mac with M4 chip. Have you specifically tried to use Siril on this new version of the MAC?
I hope there is a simple solution but I have not found it.

Please read the documentation page whose link I sent you before saying that.

It works on my M3. There is no reason it would not work with a M4.

I have tried Siril ver 1.2.4 and that version appears to be working as expected without any issues, On my Mac 4
