Silly cow is just going to have to learn how things work with newer Macs & their software.
Mac User group member updated from old 10.6.8 iMac to new 10.12.5 iMac. Now she's bought DiskWarrior 5 on USB and doesn't want to use Terminal to update DW to work with the newer system.
Extract from the quick start manual: The DiskWarrior flash drive ships with the ability to start up any Intel Mac that originally came with OS X 10.4, 10.5 or 10.6 installed. If you have a newer Mac that originally came with OS X 10.7 or later then see the section “Launching DiskWarrior while started up from your Macʼs built-in OS X Recovery” below. After your startup disk is repaired, you can use the included DiskWarrior Recovery Maker to update the DiskWarrior flash drive to start up your newer Mac.
She says the USB stick won't boot up her new iMac.
Quite right, not until she uses Terminal while started from her Recovery Drive: the DW system has to be updated to work on 10.7 or newer & Terminal is how to do it.
That said, it's a bit daft in this day & age for a software maker to ship/sell a system to work with OS X 10.4, 10.5 & 10.6 instead of the newer ones.
