Detailed Step by Step Yosemite 10.10 Install Guide Clover UEFI / GTX 760 / ALC 898 / Realtek RTL8111 I was able to setup two Dell XPS 8700 systems flawlessly with the following steps. Everything except built-in Wifi should work. The systems had stock hardware except for upgraded Nvidia graphics (GTX 760) which should not impact the success of the following steps: 1) If you haven't done so already, download OS X Yosemite in App Store on a Mac or another hackintosh. 2) As mentioned in the Pinned Yosemite Clover install thread create a USB stick: Start Disk Utility, Select the USB Drive (not the partition the drive itself), Go to the Partition tab. select Current, then 1 Partition. Choose MAC OS Extended (Journaled), select Options, GUID partition mapping (Important) and name it Install. (I tried with both USB Stick and External USB drive with success) The command in terminal shown below can take a long time depending on the speed of your USB drive (10-30mins). I recommend using a better USB stick to avoid pulling your hair out during this process. Ensure the OS X Yosemite.app is in your Application folder.
