Do you experience problems during downloading?
Check your connection in Status and Interface settings window.
Use Test Server in Config > Servers.
We will probably ask you to do a test using only basic settings.
Do you experience problems during repair or unpacking?
Enable +Debug logging in the Status and Interface settings window and share the relevant parts of the log here using [ code ] sections.
Then, you expect us to know that you had then switched to installing it on your iMac. And to know what paths your particular iMac is mounting its NAS shares to when none of us are using macOS? Unbelievable.

I just want to thank you and everyone who tried to help,I was really frustrated with the setup,you are right I did ask on QNAP forum how to install sabnzbd on my Nas, installed,but decided to delete and use my iMac instead .
Again thanks everyone and my apologies,sorry!
