I went and did a silly thing…
I initiated installation of Mac OS 9 to replace OS 6.1.2 my MacBook Pro was running. It was free, so why not? It took a long time for it do download from the app store. I thought I cancelled it, having hit esc, but it popped up when I had it. Not thinking things through, I clicked the button to install it – not realising it would take a couple of hours.
It’s been saying ‘Completing installation… Less than a minute remaining’ for almost half an hour now.
Am I screwed? Do I just let this thing run? (I have to take off for a few hours.) What happens if I do a hard reboot?
