Conquest has been running great on my Mac with OS 10.12.

Suddenly I can not log on.  Rebooted, waited a day or two. 

I get this message:

Dear Thomas,

I think you may have put ConQuest as part of your startup system, so it gets started when you log in.  If this is the case, a colleague suggests starting your Mac in safe mode, then removing ConQuest from the startup folder.  You can then run ConQuest when you want to, rather than automatically when you log in.

Please let me know if this works.

Best wishes


Hi Thomas,

These forums are for discussion and help with the CSD Python API specifically, rather than the other components of the CSD System such as ConQuest. For help with these we'd recommend contacting our user support team (

However, for this issue I'd recommend the following:

1. Open a Terminal window

2. Type:


rm .csds_defaults

rm -rf csds_data

That should then allow ConQuest to start. If problems persist, as mentioned above please do contact CCDC support for further help.
