Hi michote:
Sleep still works on my UD5-B3 after the update from 10.6.7, no sleep enabler, just dsdt from database. I tried twice but failed or i was unhappy with it. I do not trust an update that does not finish successfully due a panic. I think i nailed it on my third attempt, everything is working so far, this is what i did:
HD1-> Main system.
HD2-> Back up system (Clone of main system just on a different HD)
1-Booted HD2 and ran combo update, changed install location to HD1.
2-Latest Multibeast and changed install location to HD1, selected system utilities, audio and usb rollback.
3-Rebooted to HD1 locked at apple screen because i could not install nvidia update from 10.6.7 on HD2.
4-Connected via VNC from windows to run nvidia date, rebooted to main system again and it was all working and updated
Note: I hope #4 can help others stuck on apple screen because they could not install nvidia update after the 10.6.8 update.
