Darn Joe, Zero interest in spending 6-7 times more.... hmmm laptop maybe just back up for apps can copy back?

What need SSD to boot into? And no bootable anyhow current with SD etc ......

SD has me backing up currently my imac Mac HD, but not bootable...

What is the main difference between.a bootable and non bootable backup for a Mac HD, besides being able to work from bootable, which I've never had to Do in 20 years on Mac...
