What are the implications and consequences of executing "kill -9 writeconfig" from the console?

    I am trying to delete an account and checked the "Erase home folder securely" option.

    I now notice the process writeconfig is running about 100% CPU, and has been so for some 12 hours now. (I also notice a process launchd has been gradually creeping up in disk write activity).


    Anybody know if killing either (or both) will crap out my machine if I do it in the middle of deleting an account.

    
Thanks; any insight/advice is appreciated.


    MacBook Air 13-inch, mid-2011, OS X Yosemite (10.10.3), 256GB SSD, 4GB RAM

    In reading further it looks like killing launchd is a really bad idea as it's one of the fundamental OS X processes.

    But I'm still curious as to writeconfig.

    Oof, bummer, not sure what I would do in your situation.

    But, if anybody else finds this thread and wants some advice: I would be reluctant to do a "secure erase" on a computer with an SSD.

    The way SSDs work, you aren't really guaranteed to securely erase anything if you do that. But it will put extra wear on the drive.

    IMO a better way to securely erase the free space on an SSD is to find a big file (rip of a DVD?) and duplicate it until the drive is essentially full. Then delete all the duplicates. That should pretty effectively erase whatever was on the drive previously.
