By the way my extension manager is version 22.214.171.124
and I'm running an mac mavericks 10.9.4
quit Adobe Photoshop
sign out from the creative cloud application
sign back into adobe creative cloud, and launch the Photoshop wait for 2-3 minutes, and then check if the extension panel is there or not
To answer my own question, it appears to be an issue with the maker of the extension and not with the adobe products.
Just found this. It's probably the same with other extensions too, the developers just have to catch up.
Mac OS X 10.5 or higher
Photoshop® CS5, 5.5, 6, and CC (not compatible with CC 2014 at this time)
