For some reason there seems to be a 'mach_kernel' file appearing on the root level of my HD in Finder? I swear it wasn't there before I installed the 'Security Update 2015-002' yesterday? Anyone seeing this file after the security update as well?
 
That is a critical system file. Do not delete it. You can hide it by entering the following into the Terminal:
Code:
sudo chflags hidden /mach_kernel
 
Hi All-

I have 10.9.5 & just downloaded the security update and also now have this kernel in the root level of Mac HD. I almost trashed it, then thought I better come here to see if there is any info on it.

So I did the terminal thing, entering: sudo chflags hidden /mach_kernel, hit return, and I get this:

Sorry, try again.
Password:

I have never had a password on my system, and have used terminal recently and it worked fine. I normally hit return for the password but now I can't do this. Do I have to create a password to follow through on this?
