I have successfully installed Yosemite on my x230 using clover with UEFI method.
I have followed this tutorial to create a USB key and then install on fresh HDD:http://cloverboot.weebly.com
replace mavericks with Yosemite and add the following modifications:Step 3:
Just to explain: it will create a hidden partition on your USB key called EFI, where the clover directory will be created and the files needed to boot the USB key copied. To unhide it in order to copy the necessary kext, you need to mount it using EFI mounter v2http://www.tonymacx86.com/downloads.php?do=file&id=220
Then you can copy the following kext in EFI/CLOVER/KEXTS/Other:FakeSMC:

"copy mavericks to usb" use the following command instead of the one written:
sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/CloverBoot --applicationpath /Applications/Install\ OS\ X\ Yosemite.app --no interaction
then follow the process until the end:
Then you'll have to install clover on your hard drive so that you don't need your USB key to boot.
To do so do again step 3 "Install Clover to USB or HDD"
but this time, select your freshly installed hard drive.
You'll also have to copy the same kexts as in step 3.
You'll also have to create a config.plist. I'll put the details. It's necessary to have the brightness slider.what's working:
Sound with VoodoHDA (but doesn't detect when you plug a headset, I have to manually select headset on the sound properties)
Brighntess slider by pressing Fn+k and Fn+P
Speedstep with the following KEXT
All the USB Port in USB 2.0 mode in bios
