I had an older 2008 model iMac that I used Logmein to remote access and never had any trouble. Now I'm using a Late 2013 iMac and the program Teamviewer (since logmein is no longer free), but I cannot get the mac to wake on lan even though the setting is checked in system preferences. What am I doing wrong? I've called Apple and Teamviewer, and both said to call the other.
