Apple released iMac MXM Update 1.0 for the 24-inch iMac on Thursday. The update improves Boot Camp video compatibility and corrects a problem where users would see a black screen instead of the blue installer screen during a Windows XP installation.
To install the update do this:
- Download and run the iMac MXM Update firmware installer.
- Navigate to Applications/Utilities to find the updater application, and then double-click it to install the new firmware.
The updater is free, and available for download at the Apple Support Web site.
