How Should Internal Hd For Mac Be Formatted With Sierra

Sep 07, 2017  Internal storage devices appear under the Internal section in the sidebar. External devices appear under the External section in the sidebar. When you select a volume that already has data on it, the pie chart shows a shaded area representing the amount of data on the volume and an unshaded area representing the amount of free space available for another volume. Aug 28, 2018 - If you are working with APFS on your macOS Sierra, then you must already be aware of these. Not just an internal drive, you can also format an external hard disk as well. To start with, simply launch Terminal on your Mac.

'an error as occurred installing macOS. To use Apple Diagnostics to check your Mac hardware, shutdown, press the power button, and immediately hold 'D' key until diagnostics begins. Quit the installer to restart your computer and try again.' This is the message I get when attempting a clean install of High Sierra from the bootable USB drive.

I have formatted the HD and started clean install. It loads up, screen flashes black, and start installing. At '11 minutes remaining' error message appears. I tried holding 'D' key, but it always went to Internet recovery. Note, that I had a clean Sierra install on the computer (I was unable to download full High Sierra image otherwise) and all worked well using the same procedure: format HD, install. One thing that might be important: It is not clear to me if I should repartition the disk using the disk utility.

If so, steps to do that in High Sierra would be appreciated. Computer: late 2012 Mac Book Air, 256GB SSD drive, and 8GB memory (both standard). Hardware requitrments seems same as for Sierra which worked fine. Thank you, Radek Edit: After I restart the computer after the error message holding 'opt' key I still see my 'Install macOS High Sierra' USB and 'mac OS installer' (later had internal HD icon). Hi, Re-creating the bootable drive seemed to resolve the issue.

IIRC installation screens seemed a bit different, but everything went well. Two things that might have helped: 1. I ran dd to zero internal SSD (entire drive was zeroed wiping EVERYTHING including recovery partition. When I booted from USB drive, the internal disk did not even show up.

Once the pre-install ran (I guess SDD got formatted) it appeared as a destination for installation. As I was creating the bootable USB I was wondering if I have used the --applicationpath switch. I might have forgotten (if that makes any difference. I saw both on the net). Thank you all for comments. Cheers, Radek. Hi Radek, For some reasons macOS High Sierra is giving some headaches around, but hey positive thinking there is always a solution!

Here are is an important question, did you do create a new USB media install with macOS High Sierra you're installing or does it come from another image? That could be one reason. Otherwise if you're stuck, I would suggest to reboot with the option key and get out of the macOS install drive and reboot on your normal drive, it you still can and go to App Store download the macOS High Sierra available and recreate a USB media install. Otherwise internet recovery is a safe option.

Normally I would have suggested to use DiskWarrior but I know for a fact that it doesn't function properly on macOS Sierra. Push comes to shove, if you've got an Apple store nearby, then make an appointment with a Genius, these guys are real wizards and most of the time, they can resolve issue so easily that it is really worth it not to forget about them!
