PowerMac G5 1.8Ghz Single (late 2004, 600Mhz FSB) - The Freeze Bug


We want a bug free Power Mac 1.8 SP (late 2004)


Do you own an PowerMac G5 1.8Ghz Single (late 2004, 600Mhz FSB), and he freezes often after a uptime of 2 hours and more, if you play a Video with Quicktime in full-screen mode, a photo slideshow with Preview or iPhoto, since you run Mac OS X Tiger on it? Then read the following informations:

The affected users of the PowerMac G5 1.8Ghz Single in Germany have a Website for it. We explain in english the Freeze-Bug and the other known bugs of the PowerMac G5 1.8Ghz Single (late 2004, 600Mhz FSB).

We made also a list with Names and Serial-Numbers of affected users, and we would like to offer all of you to participate, and if you like, we add also your names and serial numbers to the list. It will show, that cannot be some individual cases only.

We plan also a special Fax Event, we send all a Fax with same Texts to Apple Ireland in Cork (for american citizens to Apple in Cupertino), with all the informations about the Freezing and the other bugs, with all Names and Serial Numbers. We would like to offer all of you, to participate the Fax Event too.

With this fax, we want to make Apple know, we will not hesitate to inform the public, the press and the consumer protection, if Apple does not offer an bugfix or an exchange of the bad Mac 1.8 SP to the concerned customers (for example a G5 dual processor Mac ).

Please have no fear, nobody except Apple, can assign the Names and Serial Numbers addresses to the real postal addresses of everyone, so your privacy is always secure. We in Germany think, we should use any useful chance, you too?

A few germans reported: Level2 Supporters said to them a few days ago, Apple works on a bugfix solution, which could be a Firmware Update or a Tiger bugfix, or combined. A possible release was assumed for the next 7-14 days, means middle of August. If the date is not kept, we plan the fax Event.

We will inform you about the special day!

Contact for questions and your suggestions (in english please): "tomvos @ macnews.de" (without the spaces between the @ char)

Power Mac G5 (Late 2004) 1.8GHz models stop responding randomly
Some 1.8 GHz models of Power Mac G5 (Late 2004) computers may experience any of the following symptoms:

- The computer may freeze when performing certain video-intensive tasks for extended periods of time, such as a full screen slideshows, QuickTime playback, or some games.
- The optical drive may not eject when you've been using the computer for about two hours.
- Internet Connect may become unresponsive when you've been using the computer for about two hours.
(This issue can affect either internal or external modems that use PPP as well as DSL modems that connect using the PPPoE protocol.)
- Attached displays may not wake up properly after the computer, running Mac OS X 10.4, has been sleeping for an extended period of time. The computer seems to wake up, but the display doesn't.

These symptoms only occur with the 1.8 GHz model of Power Mac G5 (Late 2004) computers. Apple Engineering has identified the cause of these symptoms and is developing an update to address the issue. At this time we can not provide a specific date when the update will be available, but this document will be updated as more information becomes available.

In the interim, making the the following changes in the Energy Saver pane of System Preferences may reduce the occurrence of these symptoms until the updates are available:

1. From the Apple menu, choose System Preferences.
2. Click on the Energy Saver pane.
3. Under the Sleep tab:
- Drag the slider under "Put the computer to sleep when it is inactive for:" to Never
- Drag the slider under "Put the display to sleep when the computer is inactive for:" to Never
4. Under the Options tab:
- Set Processor Performance to the "Highest" setting instead of "Automatic".
