Running OSX 10.5.8 but cannot boot from Superduper copy on external HD
Running OSX 10.5.8
Followed Superduper instructions , first partitioning a new 1TB external using GUID and extended journaled format, then doing earase and copy all application of superduper.
But when i try to use the external to boot I get error message panic "unable to find drive for this platform\ACPI\...."
Updated all software.
Attempted Carbon Copy before Superduper and was unable to create a bootable external hard drive.
Please help. Thank you in advance~
