I bought my mac mini around a year ago and today i decided to reinstall osx tiger on my machine with the proper cd's. It was going good at first everything installed properly and I was updating everything, I got to the intel update and it installed then when it started to verify it gave me the gray box with power symbol it in. I done what it said I restarted it and it came up with Unable to find driver for this platform: "ACPI" If anyone can assist me with this error that would be great.
