It's all working, I've now got it running on my PC as I'm working on it anyway. Really appreciate your help.Hi Tom - welcome to HFH.
Don't worry, you've got the project 99% completed, and you appear to have the Program field pointed correctly.
The clue for what is wrong lies in the file description for sacd_extract, it describes as a Document or text file. That means you haven't made it executable, which is an additional step required on both macOS and Linux (but not Windows), because it isn't commercial software with a signed certificate from a known developer. Both macOS and Linux turn it into a text file on download as a security feature.
The fix is easy and then you are in business, open Utilities → Terminal and type the following command:
Code:chmod +x
Followed by a single space, then drag and drop the sacd_extract file onto the Terminal window. The file path populates automatically. Press Enter.
Thats it, all done, you can close Terminal and the file will now describe as a Unix executable. All good to go, now just Run a rip.
Tom
