    I had a Mac Mini with a ssd and hdd utilizing OWC’s twin drive setup. The ssd drive had the OS (10.11 I feel) and the hdd had my residence folder and an previous model of OS X (10.7 I feel). I used to be working this setup for a number of years, with updates to the newer OS, with no permission points. The pc had a logic board or gpu failure (wouldn’t boot, energy mild on, no chime, clean display screen, fan instantly revs to full pace) so I bought a alternative Mac Mini with the identical specs and moved the 2 drives to the brand new machine. The brand new machine is not going to boot as meant.

    When I attempt to boot usually, the pc will get to the apple brand and the spinning icon for a half second earlier than shutting off. After I boot from a USB set up disk I can get to the disk utilities, and many others. The startup disk choices display screen doesn’t present an OS on the ssd, solely the hdd. All the pieces exhibits “OK” when working first assist on ssd. Operating first assist on hdd exhibits permissions downside which will prohibit booting. Utilizing “Confirm” within the menu I can navigate the contents of the hdd however nothing for the ssd.

    A pair locations on the internet have really useful making a backup residence folder on the ssd boot drive when creating the twin ssd/hdd setup, in case of permission errors or listing corruption, however they don’t clarify what the results are or repair it in the event you haven’t finished this and run into issues. I can’t bear in mind if I created the backup residence folder on the ssd.

    So, what’s conserving my Mac Mini from booting? Is there a corrupt listing or disk permissions gone haywire? If the issues contain my residence folder, is there a solution to create a brand new residence folder on the ssd to make the drive bootable after which level the OS to the right residence folder on the hdd, all with out overwriting something presently on the ssd? I’ve a sense I’ll be mucking about within the Terminal.
