Give it the executable permission with the command sudo chmod a+x /usr/bin/rootfinder. Now you can just start the Terminal and type rootfinder to run Finder as root. Again, leave the Terminal window open while you use Finder, and type ctrl-c in Terminal when you're ready to quit. When you try to sudo anything, it says: “no valid sudoers sources found”. It happened to me twice. The first time it happened to a MacBook. I tried to make some changes to the sudoers file, but it didn’t help, and I gave up. After adding an SSD drive to my Mac Pro and moving the system to it, it happened again. It's pretty much easier to install chkrootkit on an Ubuntu 18.04 Server as it's available in the Ubuntu repository packages itself. We can install it by running the command below: # apt-get update # apt install chkrootkit # chkrootkit -V chkrootkit version 0.52. We just need to make sure that we have the root privileges to use chkrootkit there. Nov 28, 2017 The root user is disabled by default. If you can log in to your Mac with an administrator account, you can enable the root user, then log in as the root user to complete your task. The root user account is not intended for routine use. Its privileges allow changes to files that are required by your Mac.
By default, sudo requires that users authenticate themselves with a password (by default this is the user's password, not the root password). Once a user has been authenticated, a timestamp is updated and the user may then use sudo without a password for a short period of time (5 minutes unless overridden in sudoers).
sudo determines who is an authorized user by consulting the file /etc/sudoers. By giving sudo the -v flag a user can update the time stamp without running a command. The password prompt itself will also time out if the user's password is not entered within 0 minutes (unless overridden via sudoers).
If a user who is not listed in the sudoers file tries to run a command via sudo, mail is sent to the proper authorities, as defined at configure time or the sudoers file (defaults to root). Note that the mail will not be sent if an unauthorized user tries to run sudo with the -l or -v flags. This allows users to determine for themselves whether or not they are allowed to use sudo.
sudo can log both successful and unsuccessful attempts (as well as errors) to syslog(3), a log file, or both. By default sudo will log via syslog(3) but this is changeable at configure time or via the sudoers file.

sudo will only log the command it explicitly runs. If a user runs a command such as sudo su or sudo sh, subsequent commands run from that shell will not be logged, nor will sudo's access control affect them. The same is true for commands that offer shell escapes (including most editors). Because of this, care must be taken when giving users access to commands via sudo to verify that the command does not inadvertantly give the user an effective root shell.
Return Values
Canon driver for mac os sierra. Upon successful execution of a program, the return value from sudo will be the return value of the program that was executed. Otherwise, sudo quits with an exit value of 1 if there is a configuration/permission problem or if sudo cannot execute the given command.

Jan 17, 2017 Method #1: Fix when macOS keeps asking ssh passphrase after updated to Sierra or after reboots. You need to use the UseKeychain option in your /.ssh/config file. From the sshconfig man page: On macOS, specifies whether the system should search for passphrases in the user’s keychain when attempting to use a particular key. Mac os sierra keeps asking for server edition.
