Late Monday, Apple released a firmware update for the Power Mac G5. Available via Software Update or Apple's Support site, the update provides:
"...changes for initializing and running your Power Mac G5. It provides some performance improvements for some PCI-X configurations, patches a security hole and improves fan behavior in Open Firmware."
We're anxious to hear from readers if this firmware update has helped with any of the loud fan issues we've covered here at MacFixIt. Drop us an email at Latefirstname.lastname@example.org.
