I’m greatly saddened to hear the news, but I can understand the reasoning behind the decision. The writing is on the wall for AppleScript & automation in general on the Mac. Script Debugger’s EOL is an absolutely devastating loss for AppleScripters everywhere.
Thank you both for all your contributions & support over the years! Wish you the best with your future endeavours.
Well hell, I was just getting comfortable. It’s like the really good in life always leaves too soon.
Thank you for all you’ve contributed in the short time we’ve been together and not taking it all with you. 
Thank you guys for all the work you have done. Thank you also for the end-of-product calendar; this is really nice to do. I wish you both great things going forward.
The journey in life and the experience from the past could set the path to imagination what we could do in the future. The hard part is not to do what we have learn its to do things nobody else have done. That was my feeling when I decided to stop using AppleScript and leaving MacScripter.net. I like to thank Mark for his effort to running the only forums that still are dedicated to AppleScript or Scripting on macOS platform for all years. I like to thank again Shane Stanley for his kindness and effort to share his knowledge in AppleScriptObjC. It become a easy path to learn how Objective-C framework was working it also set the path to do the same things in PyObjC. I do not think I would have read Apple’s API so much I have done without AppleScript that started it all for me.
I was not directly a Script Debugger user, I like to do it that hard way (no shortcuts) 
but I understand that many people use it when they need something better to debug the code.
Mark and Shane have a great journey to fill yours imagination.
Happy New Year 2025
So Long, and Thanks for All the Fish
ScriptDebugger is the primary reason I continue to use AppleScript for automation projects. Such a great development environment—but that is only half the story. Mark provided such excellent support for so many years. That was/is what is so great about small developers. The ideal.
With Shane’s help he continued to do this for years—a model for everyone. I also want forget my correspondence with Gerry, contributions from Matt, and others. Thanks so much for making my life easier for so many years. I’m sure I will still be using SD into the next decade.
