I always drag and drop vectors for Illustrator to Photoshop files and edit the smart object when I needed to but I never encountered this problem before. If the problem persists, save the document to a different file or duplicate it in the Finder." Use the ‘Get Info’ command in the Finder to ensure the file is unlocked and you have permission to access the file.

"Could not update smart object files because the file is locked, you do not have necessary access permissions, or another program is using the file. But when I double click on a smart object to update it, it opens it up the file (Which is a drag and drop vector file from Illustrator) and I try saving the changes I get an error message. So I just updated to to the new OS and I started up Photoshop cc just fine.
