Release Notes

When using Mac OS X Leopard with a computer containing an NVIDIA GeForce graphics chip, the whole screen output may unexpectantly stop responding ("freeze") when using certain graphics features of the application: Mac systems which use Mac OS X 10.5.x and a graphics processor of the NVIDIA GeForce series may fail during normal operation because the Leopard drivers are not yet working correctly. The driver is losing the connection to the graphics processor and does not recover.

Workaround: Restart the computer and open the Console application. Check if either the message "NVChannel(GL): Graphics channel exception!" or "NVChannel(GL): Graphics channel timeout!" have been recorded by Mac OS X in the system log for the time when the screen stopped responding. If yes, contact Apple stating the problem and suggest that the graphics card or its drivers have to be replaced.

 

After waking from sleep mode, the Main Logic Board Air Inlet sensor of some Power Macintosh G5 Dual Core systems shows negative or no readings: When a dual core PowerMac G5 wakes from sleep mode, the temperature reading of the air inlet sensor may show incorrect values.

Workaround: This is a known defect in specific versions of Mac OS X Tiger. This particular sensor is not correctly woken up by the operating system. We have made Apple aware of this problem and hope they will resolve it in future versions of Mac OS X. In the meantime, you can restart the computer to reset the sensor hardware, or disable data acquisition for this sensor in the preferences of the application.

 

In certain configurations, the entry "Logitech LCD Manager" may not be displayed in the list of LCD devices, even if a Logitech product with LCD support is connected to the computer (Hardware Monitor only): Although you have attached a Logitech LCD product and installed the Logitech driver software, no device entry for this product appears in the preferences panel of Hardware Monitor. The display does not work and cannot be configured.

Workaround: The Logitech LCD Manager software does not start reliably under specific circumstances. In this case, applications are not able to see or connect to the respective LC displays. Not only Hardware Monitor, but all applications trying to use LCD-enabled Logitech devices are affected by this problem. Try the following to start the LCD Manager manually:

  1. Launch Activity Monitor (from the folder /Applications/Utitilies), select the process called LCDManager, and press the stop button to force-quit it.
  2. Check if the file ~/Library/Caches/TemporaryItems/com.logitech.lcdmon.xxx exists in your home folder ("xxx" is an arbitrary number which can vary.) If yes, delete this file by dragging it to the Trash.
  3. Open the pane LCD Manager in System Preferences. This should start a working copy of Logitech LCD Manager.
  4. Quit and relaunch Hardware Monitor.

Logitech might resolve this problem in future versions of their driver software.
