I had the same problem. My solution is to turn off idle sleep and use the following sleep script:
#!/bin/bash
#how many checks are necessary to shutdown
checks=$1
#time between checks (see man sleep)
time=$2
### main loop
count=0
while :
do
if [ `who | wc -l` -eq 0 ]; then
count=`expr $count + 1`
else
count=0;
fi
if [ $count -eq $checks ]; then
count=0;
pmset sleepnow
fi
sleep $time
done
I start this script by the following launchd plist in /Library/
LaunchDaemons:
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd ">
<plist version="1.0">
<dict>
<key>GroupName</key>
<string>nobody</string>
<key>Label</key>
<string>de.uni-karlsruhe.ibds.auto_sleep</string>
<key>OnDemand</key>
<false/>
<key>ProgramArguments</key>
<array>
<string>/usr/local/sbin/auto_sleep.sh</string>
<string>12</string>
<string>300</string>
</array>
<key>RunAtLoad</key>
<true/>
<key>UserName</key>
<string>root</string>
</dict>
</plist>
As you can see, the script checks every 300 seconds if somebody is
logged in and if this test fails 12 times in succession, the computer
is put to sleep.
