Sometimes Mack heated, sometimes it gets very hot, that you begin to think about the reasons for the heating and cooling methods. For this purpose I would always see the CPU temperature in the system tray. But I could not find some good ready solution for this. So I wrote a little primitive program, the only purpose of which - displays the current temperature of the CPU for the computer on Mac OS X.
It looks like this:
The application can be downloaded here. To install it, unpack and copy the directory MacThermometer.app into /Applications directory. And if you want to make the application starts automatically when the system loads then store attached file ru.trolsoft.macthermometer.plist to user directory ~/Library/LaunchAgents/.
By default, the temperature is updated every two seconds. If this is does not suit you the refresh interval can be changed in the file /Applications/MacThermometer.app/Contents/Info.plist by key interval (see to the file end).
