Start ip drivers are missing and I don't have the disk. Mackeeper may have deleted start up drivers and restart page is background with terminal message saying start up.drivers not.found and.left system start up hanging. I tried pram and can't find start up disk. Its pocket architecture and odd 10.58 ,05 model. What do I do. Is there a terminal cmd for.restart. I tried mac- boot and it repeated errors. Maybe I threw software away accidently?
