Apple released Mac OS ROM Update 1.0, which corrects USB device troubles on iMac, blue and white Power Macintosh G3, and bronze keyboard PowerBook G3 Series computers. The numerically-confusing Update 1.0 changes the Mac OS ROM version 1.4 in these machines to version 1.6. On USB-equipped Macintoshes, the update addresses problems with unresponsive devices when the mouse is plugged into the top or left USB port and the keyboard into the bottom or right port. Updated USB-equipped PowerBooks avoid a potential crash when removing a USB keyboard while putting the computer to sleep, more consistently recognize hot-swapped media bay devices, and require that the Target Disk Mode SCSI ID is set to 2. Please note that bronze PowerBook G3 owners should check the current Mac OS ROM version (found on the System Profile tab in the Apple System Profiler application), since many of the machines are already running version 1.6. NetBoot clients running under Mac OS X Server should also install the new version. Mac OS ROM Update 1.0 is a free 2 MB download.
