A recent update to Apple's Safari browser has created a bug in watching videos on TexAgs.

To resolve the issue, you will have to set your cookies (Safari > Preferences > Privacy) to "Always Allow".

We realize this setting is not ideal for many, and we are working to find a more permanent fix. If, in the mean time, you do not wish to make the configuration change above, we suggest using the Chrome browser to view TexAgs.
