Hi,
For the past few weeks my Mac turns itself on randomly. This either happens straight after I shutdown, or around 15 - 30 minutes after I shutdown.
I have so far tried to no fix:
1 - erased disk
2 - reinstalled macOS
3 - NVRAM reset
4 - SMC reset
5 - hardware diagnostics (no errors found)
Im out of ideas... anyone have anything else I should try before I put this in the tip
iMac, macOS Sierra (10.12.6)
It could be briefly losing power and restarting when the power is restored.
To eliminated that notion.....
1. Go to: Apple > System Preferences > Energy Saver and make sure that "Start up after a power failure" is un-checked.
2. Check all of your power connects, including your Surge Protector and/or Battery Backup if applicable.
3. Reset the SMC again, as per > Reset the System Management Controller (SMC) on your Mac - Apple Support
