I also had the same problem affect one of my builds. It was solved by deleting network preferences (despite mine being listed correctly). It's fine but it somehow has WiFi as en0. If you're still having problems try logging out of iCloud and then doing the fixes listed in the guidesWell it installed fine, but now iMessage and Facetime will not log in. I'm using the latest Clover, and I cleared all cache for iMessage as the How to Fix iMessage Guide by jaymonkey instructed. I also cleared all network settings and tried a different user account. No bueno.

DefaultVolumekey in your Clover's config.plist, then it will automagically find the right volumes to boot when you're doing updates, there is no need for user interaction.
