Hi I have a question for you. I have a 2010 MacBook Pro with 4 GB of RAM and a duel core processor. If it were your machine, would you upgrade to Yosemite? My problem is that I have preordered a Vario Ultra from Baum and it will only work with Yosemite. I’ll have to cancel the order and look into another braille display if upgrading my Mac isn’t advised. Thanks. Lena************ You are subscribed to the mac4theblind mailing list.
