Hi,
Thanks "fortra" -- for ooVoo this is an old thread as ver. 2.2 is available.
Dan, to answer your question about CPU usage, I want to point out that with MACs, they measure CPU usage based on an individual CPU, so if you have a Quad Core, you can divide this by 4, so 50% is really a 12.5% load on the computer. Anyway, the video should be fine even if you have one CPU with a 50% load.
Please tell me where it says the plans are only available for Windows (maybe we have a mistake somewhere). In the past this was true but currently all of the monthly plans and pay-per-use credit options are available for MAC users. You only need one 6-Way plan to connect to 5 other participants but you will need to invite the third, forth, fifth and sixth users unless one of these users has a paid plan or received the premium features in an initial trial period.
I hope this information is helpful and thanks for using ooVoo,
ooVoo Marv
