Mac iCloud and Spontaneous System Reboots

The other day when rebooting from a system update I was presented with the option of using an iCloud account, instead of my normal system login account.

I figured, why not? What's the worst that can happen?

What did happen was unpredictable spontaneous system reboots. (Over 6 in one day).

I studied the syslog messages for what could be happening (and there were a lot to scan through).

There were a lot of messages pertaining to iCloud resources and authentication.

I reverted to my normal system login account and disabled the iCloud hooks that I could find.

It's been over 60 hours and I have experienced 0 spontaneous system reboots since disabling iCloud on my Mac.

See screenshots below:

  • I do not appreciate Apple's attempt to force me to use their paid iCloud services.
  • If Apple continues down this road, I will dump my Mac OSX systems and develop soly on Linux-based systems
  • I don't think I'm alone in this. I am a developer. I paid good money for my Mac system and use it for development and don't have time for these marketing hassles.
