Joe, Darn! Why you spending the six hours, you did not have a bootable backup? Darn... so without a bootable, getting you Mac HD back to good, is a bit of a harrowing time killer?

I think I'll risk it until those 1TB. get to $150 .. actually all I need it 1/2 TB for the new laptop.

My 27" imac mid 2015 hopefully still has a few Mac OS years ahead, how many versions? I don't know.... really then the hope for the imac 27" is that prices are lower on SSD externals and then super duper will be back in action....
But must have SSD for bootable? Pity.

Why need parallels, can't just boot into old OS? Fine though $50 year tolerable.
