Unfortunately, the Hangouts plugin currently only supports Intel based Macs. The reason is that we require the extra processing power found in the Intel chips. This means you will not be able to install the plug-in on a PowerBook, iBook, G4 or G5 Mac. Learn more about the technical requirements.
If you are using an Intel-based Mac and receive this message with Firefox, please disable the option to Open using Rosetta:
- Right click on the Firefox icon in your Finder.
- Select Get Info.
- Uncheck Open using Rosetta.
- Quit Firefox and restart.
