What is this (mach_kernel)? I have just noticed it today after update to 10.5.7 was completed. It shows on my hard drive as a plain text file 9.9 MB in size. I tried to delete it but stopped when my administrator password was required (I assumed it might be important). If it is important can I make it invisible?
In fact it should not be visible. Are there any other items listed such as "var" or "etc"? If so then something went slightly amiss during the update. It won't affect you in any way, but these items should be invisible.
Go right ahead and make it hidden again. What you are seeing is just a file that is part of the underlying unix-like structure that OS X is built upon.
I'm not certain why after updates, the file seems to pop up, unless it's some backup or copy left over from the update.

Clearly you completely misunderstood the post to which you are responding.
The response was not to the OP but to Kappy.
Measure twice; cut once, my grandpappy always said.
There are several ways to make the file invisible. But we have to know which way to proceed.
First, in a terminal, enter the following command (we are only looking, not doing anything yet)
ls -al@ /
and then copy the line ending with
mach_kernel
which should read something like this:
-rw-r--r--@ 1 root wheel 10318880 Nov 24 20:39 mach_kernel
and copy the line below it if it exists. It will start with
com.apple.FinderInfo
and may have a number after it.
Once we see what the file descriptors are we can move on and fix it.
Most likely a simple
chmod
will suffice.
Visit the link I provided. I apologize that the original post somehow got messed up, but the one with the plain URL seems to work. Click on it and follow the instructions.
This is Paul. Thanks for your response. I'm now somewhat confused. I gather that the mach_kernel is important and should be invisible. I can't find out how I should make it invisible however. The link doesn't seem to address this and I'm not sure what the other comments mean in the discussion thread. Sorry if I've created a problem.
