Hi All,
If you are still facing the issue on AI CC 2014.1 that drag-drop is not working in the Libraries panel (Design Library panel) then please follow the following steps:
1) Launch the MAC OS "Terminal" application: Applications/Utilities/Terminal
2) Type or copy paste the command:
sudo /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.fra mework/Versions/A/Support/lsregister -f "/Applications/Adobe Illustrator CC 2014/Adobe Illustrator.app"
3) Press the Enter key
4) Quit AI CC 2014.1 (if it is running) and re-launch
Note:
If you have installed AI CC 2014.1 at a custom location than you need the following command in your terminal:
sudo /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.fra mework/Versions/A/Support/lsregister -f "<Path of your Adobe Illustrator.app>"
Please do let us know if this fixes the issue or not.
You can write an email to ShareWithAI@adobe.com along-with the forum link in the mail.
Thanks & Regards,
Raghuveer Singh
