I have successfully installed Yosemite/Clover on my ASUS Z97-AR/Gigabyte GeForce GT740, but not without a bit of trouble.
1. I could not install Clover on the boot partition after install. It took me a bit of time to realize that Yosemite installer converts the volume to CoreStorage which becomes 'disk1' and that seems to where Clover installer tries to install the loader.
I had to revert the volume from CoreStorage back to generic volume and then bootloader installer worked well.
After that, I just copied over the config, SSDTs and kexts from the Mavericks install, and expected a fully working system - but not just yet.
2. AppleIntelE1000e failed to load during boot every time. The error was that it could not resolve the dependency to 'com.apple.iokit.IONetworkingFamily'. This kext showed up in kextstat, so I just did 'sudo touch /S/L/E' to rebuild the cache.
On reboot I saw that AppleIntelE1000e now loads fine, but this time the system did not boot at all - instead, it just went for an endless reboot loop.
3. Cleared all audio-related patches (config entries for kext patches and realtekALC.kext), downloaded toleda's audio_CloverALC command for 10.10 (
https://github.com/toleda/audio_CloverALC/blob/master/audio_cloverALC-100.command.zip) and re-installed the audio.
After reboot I have HDMI-only audio, no other inputs/outputs, but I suppose that was expected for 9 series mb.
At this point I ran migration assistant and brought all the data from the older Mavericks install.
Seems to be working fine so far.
A couple of minor things:
- tried to convert the volume back to CoreStorage, but that seems to be breaking kext patching somehow, the system boots but with no audio, so I rolled it back.
- it would be nice to have a microphone working, but not that important for me
Thanks to the Clover team and toleda for the work
EDIT: after some more testing, there's good news and bad news.
Good news is that all audio controls came back.
Bad news is that audio issues (sound cutouts which seem to appear when browsing internet) are back too.
