Siril/StarNet Integration Trouble

I feel like I’m missing some microscopic detail here, but I’ve searched the discussion archives pretty thoroughly and haven’t found a solution yet.

I am trying to get Siril and StarNet2 to play together on my MacBook Pro under Catalina, and nothing I can do will get it to go. I am able to run the StarNet shell script successfully in Terminal, and I can direct Siril to see the StarNet++ executable in the Siril prefs and make that link stick, but when I go to “Star Processing” in the Image Processing tab in Siril, the StarNet choice is greyed out.

I’m running a freshly-downloaded install of Siril 1.2.1 and a freshly-downloaded install of the StarNet 2.0.0 Command Line tool for MacOS. The laptop has a fresh clean install of Catalina (MacOS 10.15.7), and I’ve apparently done all the Terminal and OS Security gymnastics to get the MacOS to see and run StarNet.

Where do I go next?

Does StarNet run alone on your computer?

In the command line, yes.

Problem solved, although I’m not at all sure how or why…

I deleted the StarNet CLI folder & files, downloaded a second clean install archive of the CLI/Mac version, and ran all the appropriate tweaks in Terminal to “bless” the files so that the Mac’s security noids would allow them to run…

Et Voila! Now StarNet works just fine, both running independently in the Terminal command line interface and also working within my Siril installation. I have absolutely no idea why it didn’t work the first time, but unless and until it stops working, I’m not going to worry about it any more.
