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?
