This is a recommended update.

• Added support for 9 more machines, for a total of 13. In addition to the Power Mac G4 MDD, the June 2004 Power Mac G5, the 2004 iMac G5 and the 15-inch MacBook Pro, we now support the Late 2005 Power Mac G5 (including the Quad), the April 2004 and October 2005 15-inch PowerBook G4s, the 2005 12-inch PowerBook G4 and every current Intel Mac, i.e. every Mac with an Intel Core 1 Solo or Duo (”Yonah”) processor.
• The timer now disables during sleep. When the machine is about to go to sleep, MenuTemperature now stops polling. When the machine has woken up, polling resumes. This will hopefully fix sleeping issues which some have experienced.
• Various minor performance optimizations and other enhancements.

If someone could provide more localizations, I would gladly add those.

Here’s the download.

P.S. (this is only relevant for users on Intel Macs): As someone has pointed out, MenuTemperature currently doesn’t work well if you have set it to launch on log in, unless the SpeedIt kernel extension is already otherwise running. This will be fixed in a future release. For the time being, I recommend in this case that you add the line

kextload /Library/Extensions/speedit.kext

to your /etc/rc file, before the last line, so the end of the file should look like this:

touch /var/run/.systemStarterRunning

if [ "${VerboseFlag}" != "-v" ] ; then
        /usr/libexec/WaitingForLoginWindow
fi

kextload /Library/Extensions/speedit.kext

exit 0

You will need to authenticate in order to save this change. After a reboot, SpeedIt should run automatically, and MenuTemperature will recognize this and no longer ask for a password.
