Hi,

I am suddenly getting a “Cannot open the Cosmos Browser, because Cosmos Service is not running.” error in C4D (Mac), when trying to Open the Cosmos Browser. How do I fix this?

Thanks,
Anders

You can try the below instructions and/or contact our tech support at https://support.chaos.com/hc/en-us/requests/new

Uninstall Chaos Cosmos by going to: /Applications/Chaos/Cosmos/uninstall/Uninstall
If they exist, remove the following folders: /Library/Chaos/Cosmos/Library/ChaosGroup/ChaosCosmos
Download and install Cosmos again: Download | My Chaos

Check if Cosmos is working now.

In case the above steps did not help:
Execute in Terminal: sudo launchctl unload ~/Library/LaunchAgents/CCBService.plist
Delete: ~/Library/Application\ Support/Chaos/Cosmos
Execute in Terminal: sudo launchctl load ~/Library/LaunchAgents/CCBService.plist

Check if Cosmos is working now.

I hope this long-standing, recurring issue is on the To-Do list to finally fix. I tend to avoid Cosmos updates until I have the to time wait for the “only seconds to update” which always take MUCH longer and then the “unable to open…” message. Then you have to re-install Cosmos. More and more assets are being moved to Cosmos, but we still have this issue and still many poorly converted materials as well.

First solution did the trick. Thank you!

That is a workaround a problem with the software, not really a solution. It does get you back online, but…
