Today I made the happy discovery that even our aged 580 series Smartboards work with Lion. Yay! Our school has been gradually buying Smartboards over the last decade, which means some classrooms have some very antique models (with serial to USB cables and the old-style round erasers. I once rang Smart’s UK technical support about one of these boards and they were in complete shock that they still worked at all…). I was not looking forward to paying thousands to replace them when we either bought new Lion Macs or upgraded from Snow Leopard.
Smart still claim that OSX 10.7 isn’t officially supported by their Notebook software, but they have released a patch that fixes things up well enough.
