In addition to information on diagnostic LEDs and self-installable parts, Apple has now launched the iMac G5 Troubleshooting Assistant. The Web-based support solution helps iMac G5 owners troubleshoot problems with their new desktop. It covers common questions about the new iMac and also walks owners through a series of time-tested instructions to help resolve support issues. Additionally, if you get stuck while using the assistant, you can click the “chat with a support agent” button to talk to a real person (every day from 6:00 a.m. to 6:00 p.m. PT).
