All up and running here (Version 11.0 Beta 20A5395g).
Initially had a freeze booting up with the apple logo stuck at 90% of the progress bar, and USB devices powering down.
Went closely through my config.plist, updating every aspect - patches, DSDT, settings - and found a few errors / changes compared to the latest 0.62 sample.plist file. For example, somehow my secure boot setting had disappeared from config.plist.
Anyway - anyone having problems it is - as almost always - likely due to a config.plist issue (easier said, than fixed!).
