A new release of ooVoo for Mac is available, version 18.104.22.168. While still technically a "beta" release, this update brings the Mac version much closer to the Windows version. The major addition is video call recording, which is a very nice feature. As far as I know, the only major feature that is still missing is "video effects", and personally I wouldn't even consider that one "major" - but I suppose others do.
I don't have a Mac, so I can't test this release myself. I would be very interested in hearing from anyone who is able to test it. How does it work, how does it compare to the Windows version, and so on.
