Hi all, I've got a ~5 year-old intel Mac mini that failed to reboot after a simple Font update. No matter what I try, it begins the boot process just enough to get to the logo and spinning wheel, but stops there. I've tried target disk mode, boot from install DVD, single-user mode, verbose mode, flash PRAM, and every other keyboard combination I can find and nothing has any effect. They literally change nothing about the way it boots. It's as if the keyboard and DVD drive are being ignored (I'm using a wired USB apple keyboard). What do you think, is my mini hosed?
