So, going off of Maverick's supported list: iMac (Mid-2007 or later) MacBook (13" Late 2008 Aluminum, Early 2009 or later) MacBook Pro (13" Mid-2009 or later) MacBook Pro (15" Mid/Late 2007 or later) MacBook Pro (17" Late 2007 or later) MacBook Air (Late 2008 or later) Mac mini (Early 2009 or later) Mac Pro (Early 2008 or later) Xserve (Early 2009) What is the prediction for the oldest computer that can run 10.10? Since it's to be expected that Syrah will have more iOS like gradients and design elements, I'm sure that a more powerful graphics card would be required to run it 100% (i.e. no feature disabled). I'm sure my current MacBook Pro (Late 2011) will support 10.10 fully (other than the features introduced in ML/Mavericks that require the newer hardware), but considering the changes made and the fact that this computer only has an Intel HD 3000, I'm slightly worried. Apple said they wanted even more Macs to run the latest hardware so they lowered the minimum specs, but how low can 10.10s be lowered before the experience is ruined?
