*WARNING* Mac Errors

Go to solution Solved by FoxyOrange,

I don't know if Mac Minis have a recovery mode like the rMBPs do. Did yours come with an OS disc? If yes, you can boot off of the dvd and try and see if you can fix anything from there. If not (or if it doesn't have an optical drive) then chances are there's a built in recovery partition which you can boot off of. IIRC you hold down ALT while booting up and you can select which device to load up. 

To restore your personal files, if you know someone else with a mac get them to come over (or bring yours to their place) and connect the two via Firewire or Thunderbolt, have their computer powered on and logged in and after they're connected, hold down "T" (you need a keyboard plugged into your Mini and must hold down the key on that keyboard) as your mini boots up. It should show up as an external hard drive on their end, you can back up your files that way. 

That same person's mac could be used to create a bootable installation of OS Sierra too, if I'm not mistaken. You would need to format your drive though, hence why you'd wanna do the target mode backup thing.

So I finally decided to upgrade my Mac Mini's OS to the new Seirra or whatever it was called, and the power went down for 10 seconds or so. My PC is fine, thankfully(except the power supply became unstable so I changed that), but my Mac that was halfway through an OS update has crashed and now shows the error code that's seen in the attachment.

RIP work station

interrupted halfway through an upgrade is just too unpredictable to fix. i assume you dont have another mac or a USB boot rescue. You should be able to sign into apple store from another computer and download an installation disk.

yeah I know you can create a bootable disk from another Mac, which I don't have xD. My last resort would be to create a Mac virtual machine and create a bootable from there

It's a 2014 Mac Mini, so it doesn't have an optical drive. However, I will try to load from the recovery partition.

When I installed Yosemite on my rMBP things went really bad really quickly. If you format the drive (back up your files first!) you can have it download the OSX ver it came with out of the box via the internet but it's really slow. If you know anyone with a mac you can use theirs to create an OS install USB drive much like Windows. I'm not familiar with this process but I know it's possible. The benefit of doing this is that it saves you from downloading through slower servers and you get straight to a newer OS rather than an older one.
