Imveryinsane Posted September 8, 2013 Share Posted September 8, 2013 Hi, sorry if my post is not in the right section, or something similar. I've installed Mavericks, and I'm not so happy, because the MBP 17" mid 2010 seems a bit slower and the trackpad doesn't work well. So, wanting to install again the native OSX of my MBP model, I initialized the hard disk, I restarted the MBP and, using the original dvd with snow leopard installer, I tried to install it in the hard disk, but BIG SURPRISE it doesn't work more! Seems that something in the firmware has been changed and doesn't allow to install snow leopard in my MBP. How can I solve this trouble? Link to comment Share on other sites More sharing options...
