Hi
I have a problem to upgrade from el capitan to sierra.
I had download sierra from App Store and when I reboot and I choose Boot macOS Install, it freeze.
These are the the last line code:
local.com.apple.xpc.launchd[1] (org.ntp.sntp.134) : Service exited with abnormal code: 1
busy timeout[0], (240s), kextd wait(0): 'AppleACPICPU'
I don't know to resolve a problem. Can you help me,please?
