Known problems

Screen saver

The screen saver is activated and is taking CPU and memory :

$ ps ax | grep -i screensaver | grep -v grep

/System/Library/Frameworks/ScreenSaver.framework/Versions/A/Resources/ScreenSaverEngine.app/Contents/MacOS/ScreenSaverEngine -loginWindow

You can desctivate it this way in command line :

$ sudo su -l "ci" -c "defaults -currentHost write com.apple.screensaver idleTime 0"

You can check it this way :

$ defaults -currentHost read com.apple.screensaver idleTime

You have to reboot your instance :

$ sudo shutdown -r now

No root user

Mac OSX has no root user, but ci user has been granted.

$ sudo my-command
Password: **ci password**

NTP

Mac OSX ntp is not always up to date. It is advised to use INRIA’s one

$ systemsetup -setnetworktimeserver ntp.inria.fr
