Closed Captioning with CaptionSync allows you to upload batches of files using our AST-Link droplet for Mac. This article shows how to use it when you upgraded your Mac.
Fortunately, the solution is simple – upgrade to the latest version which is found on the help page in main browser window. Basically run the install.sh script and choose the Overwrite options, and make sure you copy the Drop to CaptionSync (non-rush).app and Drop to CaptionSync (RUSH).app over your existing ones.
If this doesn't work, open a ticket so that we can help you troubleshoot this. Additional information is helpful:
Upgrading to Sierra:With the release of macOS Sierra, Apple has updated its cipher requirements and moved away from DSA (SSH-DSS) keys to RSA keys. If you have AST-Link already installed and have upgraded to macOS Sierra, you will need to re-install the AST-Link for Mac droplet to ensure an RSA key is created. First, download the latest version of the droplet from the help page, in your account. Then run the install.sh script, choosing the Overwrite options, and make sure you copy the Drop to CaptionSync (non-rush).app and Drop to CaptionSync (RUSH).app over your existing ones.
Once the keys are created, you'll need to add them to your CaptionSync account, like described in our tutorial.
