With LGfL, they are quite strict on what devices on their networks send email. However, they are happy for you to make use of Google’s SMTP server.
Things like Profile Manager make use of email for inviting users onto the Managed Distribution programme, so I wanted to setup our Mac server to be able to send emails like that. After a bit of searching, I came across this brilliant explanation of how to send mails from localhost. And it seems to have done the trick!
We run our SMARTBoards in school from Mac minis, some of which are old enough to have DVD drives and so which make use of Super Drives. Anyway, since Mavericks there has been an issue where the DVD player will crash upon loading. Annoying.
After trying out things like resetting the PRAM and the SMC, it turned out that the issue was due to the second display. The machines have two displays: a monitor connected via DVI and a projector via VGA (which are mirrored). I tried changing which screen the display was optimised for (in System Preferences > Displays) and this seemed to do the trick. Yay.
