Tennis4Two - The Roots Mac OS

XNU is the computer operating system (OS) kernel developed at Apple Inc. Since December 1996 for use in the Mac OS X (now macOS) operating system and released as free and open-source software as part of the Darwin OS, which is the basis for the Apple TV Software, iOS, iPadOS, watchOS, and tvOS OSes. Go To Folder is easily one of the most useful keyboard shortcuts in the Mac OS X Finder since you can jump anywhere instantly, and the root directory is no exception: Anywhere on the Mac desktop, hit Command+Shift+G, then type / and hit return to jump to root (Macintosh HD).

Developer Lem Ergin has discovered a serious bug in macOS High Sierra that allows anyone log into an admin account using the username “root” with no password. As per reports, it works when anyone attempts to access an administrator’s account on an unlocked Mac. Besides, it also allows access to the login screen of a locked Mac.

Update: Apple has released Security Update 2017-001 to fix the bug that enables access to the root superuser account with a blank password on any Mac running macOS High Sierra 10.13.1.

Apple is already aware of this bug and has issued a temporary solution to the problem.

“We are working on a software update to address this issue. In the meantime, setting a root password prevents unauthorized access to your Mac.” – Apple

  • The introduction of the new iMac was a huge event for Apple. After all, at its heart Apple is a hardware company, focused on selling cool boxes of silicon to comsumers. The introduction of Apple’s new operating system, Mac OS X, in many ways will have a more lasting impression on the computing world’s landscape.

How to Create Root User Password on Mac using Terminal

Step #1. Launch Terminal. (Simply open Spotlight Search → Type Terminal → Open it)

Step #2. Now, you need to type: sudo passwd -u root

Step #3. Now enter the Mac System password.

Make sure not to disable the Root User as it will blank the password and let the bug work again.

That’s it!

Wrapping up:

Apple will soon release a permanent fix for this bug. In the meantime, use this solution to shield your Mac.

after you su to root in the terminal, type 'ps -ax' and you should see all processes, find the one you want to kill, and 'kill -9 #INSERT PROCESS ID HERE#'

i forget what the -9 is for, but it's good in case something doesn't want to be killed, so -9 is kind of like a kill with extreme prejudice. You can always read the man pages...

The -9 flag will terminate the process immediately without giving the process a chance to exit cleanly. Using -HUP (hangup) is 'nicer' in that the program may be able to shut itself down, but OTOH -HUP doesn't always work and you have to resort to -9 anyway.
For more information open your terminal and type 'man kill'.

The usual way to restart a daemon to reconfigure it is to use kill -HUP. Dunno if it works for mysql but I've done this many times for inetd on solaris 2.6.

Your description of -HUP sounds more like the definition of -TERM (-15).
Kill -HUP is sometimes used to tell a process to restart/refresh. Often it does absolutelty nothing. The author of the program decides what to do in response to a -HUP.
Kill -TERM tells a process to shutdown (TERMinate) and gives the process the opportunity to do so cleanly.
kill -KILL (aka kill -9) is a shutdown that doesn't allow the process to shutdown cleanly.
If you type 'kill -l' (that's an 'L' not the number one) you'll get a list of signals. Count them off to find the numeric equivalent.
kill -l
HUP INT QUIT ILL TRAP ABRT EMT FPE KILL BUS SEGV SYS PIPE ALRM TERM URG STOP TSTP CONT CHLD TTIN TTOU IO XCPU XFSZ VTALRM PROF WINCH INFO USR1 USR2

Having access to the root account is a sharp & powerful double-edged sword.
It's not by accident that Apple locked it out by default, and that decision
shouldn't be crossed lightly.
In most cases, `sudo` is a far safer tactic. It allows you to run a command
as another user (such as of course the root account), and you're not left in
that other users account where it is all too easy to make a mess of things.

Better by far here would be to find & kill the process in question this way:

That last line is a test to make sure it worked. If it didn't, try
`kill`ing again with numbers increasing from 5 to 9 (shifting from safer
'let it die gracefully' commands to riskier 'alright just shut down NOW'
commands):

It should work by the time you get to -9, but hopefully sooner.

Of course, as another poster noted, this isn't the right way to do it
anyhow. The mysql distribution should have included a shutdown script. If
I knew mysql better I'd quote the command & syntax myself, but the other
poster already said it and, moreover, your mysql documentation should
surely have mentioned how to start & stop the server properly.

Read The Funny Manual!

Part of the previous post is BAD advice. Doing a kill -5, -6, -7, -8, before resorting to -9 is nonsense. To kill off a process, try -15 then -9. Each numeric argument corresponds to a different signal. The 'kill' command is a misnomer since it's a tool to send signals to processes, and only one of the signals happens to be '-9', the kill signal. For example, kill -8 is equivalent of telling the process it has experienced a floating-point exception and you want a core dump created (a huge debugging file, useless in this context). Here's a list of signals, their numbers, names and descriptions. The info came from 'man sigaction', I added the numbers for clarity.

I stand corrected. Very interesting.

Phillip,
To see all the processes type 'ps aux'. Personally I created/edited the .cshrc file in my home directory to include a line with the following
alias ps 'ps aux'
and once you launch a new terminal window ps will now give you all the details to identify pid's on running processes.

Surely it's a bad idea to shutdown any kind of database server this way (anybody who's had to force-quit FileMaker will know what i mean...),
Has anybody tried:
cd /usr/local/mysql/bin
./mysqladmin shutdown

As many users have discovered you can't get the mysql daemon to quit using mysqladmin shutdown. This is a bug that exists for all BSD Unices, and not just MacOS X. Some have suggested it is because the signals that are generated by mysqladmin shutdown are blocked in some way. There are a whole bunch of threads about it all over the net, as a search on Google for terms like 'mysql admin shutdown kill can't' will attest.
If anyone finds some solution I'd love to hear about it. For now it looks as if the only SAFE way to shut it down is to turn off the automatic startup of mysql and restart the computer.
You can sudo kill it if you don't have your root account enabled.
sudo kill process id

Mysql on OS X is ugly. Theoretically you should be able to shut it down cleanly with the
shutdown command from within mysqladmin, but that doesn't sem to work.
I have seen it written that the only clean way to deal with the problem is to
keep the shell which launched the safe daemon, interrupt it with CTL-Z, do
a ps and kill the spawned daemon brood, then kill the broodmaster.
Please correct me if i am wrong. I am waiting for a package which one can have
real confidence in. I have installed mysql on linux, linux ppc and OS X from original
sources. It integrates nicely into the redhat linux daemon start/stop runlevel scheme,
but i don't know how this issue is handled by Mac OS X.

Sending a server process a normal kill signal first is a good idea, lets it know that
it should exit gracefully and gives it a chance to behave like a gentleman :)
By the way, mysql is a very bad citizen, see my post below.
