I've got a Tiger Retail Disc that I've used on 2 previous machines without a hitch. Now, I urgently need to install Tiger on a 12" 800mhz iBook G3, yet after thirty minutes, it tells me to Try Again! Some erros tell me that there are essential files that can't be copied. "Unable to copy package source file /System/Installation/Packages/Essentials.pkg/Contents/Resources/BundleVersions.plist" "Some files for Essentials may not have been written correctly" I can't use Target Disk Mode. What other ways can I cram Tiger into this thing?
