Hi I finally found the time to install Yosemite. I had just one problem on installation phase during the network configuration (jump back to the beginning, kind of a loop) but I skipped. Now I've the system but the network doesn't work also no AUDIO. Can you help me please. I've added my configuration. DSDT_All.zip

Hi, I'm new in the forum and I would like to have some suggestion on how to proceed to install Yosemite on my Lenovo edge e540. I tried with Yosemite Zone but the installation stop after the first screen. Thanks
