Sep 21, 2016 - macOS Sierra is available as a free upgrade right now, but many people got. On any Mac dating back to 2010, and on MacBooks and iMacs from 2009. Older hardware will still work with OS X 10.11 El Capitan, which you're.
Click to expand.On the topic of hardware issues and old laptops, I have the 2011 MBP that is known to have hardware issues with the discrete AMD graphics card. I'm still running Snow Leopard and very interested in upgrading to El Capitan from all I've read, but I feel like I need to keep my laptop running on the Intel graphics, which I do with gfxCardStatus. Does anyone know if gfxCardStatus works with El Capitan? (Or else that the OS can natively restrict the graphics to the Intel chip?) I don't like the chances of burning out my logic board otherwise, and I want to keep going with this laptop until the Skylake release!
