I downloaded a disk image “IOUSBFamily-315.4-log.dmg” for Mac OS X 10.5.5 Build 9F33? and I installed, but I didn’t unplug my microsoft wireless optical receiver for my wireless keyboard, and mouse. After reboot, my mouse and keyboard stopped working!! So I wasn’t able to do a next step : “Download the disk image “IOUSBFamily-327.4.0-log.dmg” for Mac OS X 10.5.6 Build 9G55””
I bought microsoft mouse and keyboard (not a cordless one, for mac!) an hour ago, came home plugged in, and still nothing. My mouse and keyboard port is dead?

I can’t do anything with my mac, without mouse or keyboard!! Please help me , what can I do!!!!

You need to go back to the 10.5.6 build. Check out the dev-team’s blog for filenames and instructions.
