There seem to be a number of issues with 10.12.4. I'm not sure how many of them are related, but I've had a couple occurrences where the system would reboot after entering the password of any user account. I've done the usual troubleshooting, resetting, safe-mode, etc, but I can't seem to get any of the accounts to log in. After contacting Apple support, both their L1 and L2 staff could only recommend that I wipe and re-install everything again. Neither seemed to be aware that there were issues with the 10.12.4 release. Has anyone else run into this issue and know how to fix it? I'd hate to waste time re-installing our environment on these systems every time something like this occurs. The last two times this happened, was on two different brand new 15" MacBook Pro touch.
