I'm stuck in a loop. Installation in progress then it freezes prompting a restart. The restart start the process all over only to freeze again. I'm on my third try... am I off to see a Genius?
com.apple.DiskManagement error 0
iMac, macOS High Sierra (10.13), installation
Obviously conserving your data is most important. You need at least Time Machine backup and if possible an external bootable clone as well. Carbon Copy Cloner is one well known app for this.
If you also copy the High Sierra (HS) installer on to the clone disk, it can be used to erase, repair, reformat, reinstall and migrate back, your system.
Booting from outside your system and running Disk Utility (DU) "First Aid" from there, may solve the disk error problem, where using the Recovery Partition is limited. By the way, in the DU View menu, select "Show all Devices", and run the first Aid on each volume shown. The main disk often passes ok with errors needing to be fixed on the OS volume itself.
If you have not used APFS and your HDD's are still with HFS+, erasing and reformatting may not be required and the disk may repair ok.
If you cannot now access your computer, maybe a friend's clone could be used for the repairs and running the installer again. Unless you actually erase the disk, your user account should still be be there.
I you login to your account, in "Categories", under "Hidden Items", there is "redownloadable Purchases". My previous OS's are listed there.
Hi in speaking to a genius I was informed that High Sierra needs 32gb. I got this and it installed on to my usb stick without issue.
Dave
Attempted the Disk Tool - thank you- but that didn't do anything. I'm still stuck in loop trying to get the OS to install and its failing. I guess I'm going to need to create an appointment at the store.
Wow.... I've done big cats, big waves, mountains and the fully baked High Sierra is the first install ever to brick a computer of mine. 24 hours after making my first attempt, I cannot get past 43 minutes to go before it gives me the "disk error 0".
This was a very full terabyte drive... There was only 60 Gig available when I started. The first install attempts "appear" to have consumed that space per Disk Utility. I've since dumped a lot of content ($40 Apple Thunderbolt cable purchase to make that happen) from the drive and now have over 200Gig available. It doesn't matter- the installer will not proceed and disk utility says there's nothing wrong.
I suppose it this was bound to happen one day, I guess this is the day. I don't have a solution other than I suspect to format the drive and then restore - wont. that. be. fun.
FWIW, this is a Mid 2011 that serves up music and sometimes does work. Outside of being chock full of stuff, its was typical mac solid. I suppose the file change for this legacy drive is choking it but someone smarter than me will have to prove that. Drat.
I have the restore to look forward to. Won't. That. Be. Fun.
Hi yes I’m getting exactly the same error message as you. Same processs, 40odd mind estimated, recalculates time left, 40 mins then hangs with High Sierra cannot be installed. Restart.
I’ve rang Apple who took me through, various recovery procedures but to no avail.
I’ve even tried installing HS on an external usb hd, but not having that either. I don’t want to loose what I have on the internal he as I have no backup, yes I know my fault that.
But how do I get my Mac back working again as pre Hs install!???
Dave
I’m obviously not alone. I hope Apple do something about this. I’ve never had issues with updates before.
I think at the very least Apple should let you roll back to pre update.
It would save them lots of ear ache too.
Dave.
I'm on my third attempt at putting High Sierra on my 27" Mid 2010 iMac (trying to upgrade from the latest Sierra 10.12.6. So far the disk (50% full so 500Gb available) rumbles away for 40 - 45 minutes and then says com.apple.DiskManagement error 0 which - as an error message is about as useful as a chocolate teapot.
I (fortunately?) still have the macOS 10.12.6 installer and I have created a bootable USB to use with my iMac. So far so good. I have yet to get the error 0 message but I am lokking at some of the comments here where people have lost all of their applications. Time will tell. I will update tomorrow!
Like I said, in its great wisdom Apple seems to have made Sierra impossible to find. I was lucky that one of the IT people at work has a collection of old MacOS installers. But that doesn't help anybody else.
Hi my mac is bricked by the High Sierra update. So I’m now (according to Apple support) reliant on my pc to restore my Mac to its full health.
Now I’ve created a bootable usb drive, using transmac. But how to I get the Mac OS dmg on this? Where is it, on my Mac I just updated using the App Store.
Also I do not have my original Mac OS (snow leopard) install disk.
Any ideas?
Dave
Hi thanks for that, yes I might have to take a look online see what’s available and by how much. I don’t think I should have outlay anything mind as this is Apples doing. They should allow you to either easily “restore from ladtcknown good”, yes take a leaf from the Windows world. Or let you download an installer from there own site, whether that be Mavericks, Elcapitan or Sierra ... frustrating.
Regards
Dave
No too late... thanks for the idea, but Sierra isn't available in "My Purchases". Called into my Support Rep the day before his work week started and still haven't heard back. My iMac is a sculpture presently, sitting idle and operating in a very green way - it's been off a week. I'd like to get it working next week but I'm not holding my breathe. I'm not keen to do a clean install.... I might need to find another user and send them a thumb drive to get Sierra.
A new twist... I borrowed a 16gb usb stick and started up my mac in Internet recovery mode (shift, option command) .. got to the MacOS utilities screen, formatted the usb as journelled as discussed on the phone with Apple support. Was really hopeful, went through same routine, finally got to the grey screen with the progress Bar ... and boom, I install failed as not enough space on the drive..... it’s got 16gb!!!!!!
Regards Dave.
Yes this may be the case but why should you want to put a faulty version of MacOS High Sierra on a USB. It's MacOS Sierra that you need first so that you can revert when you get into the com.apple.DiskManagement error 0 loop.
I attempted with a 128GB USB. Via disk mode on the bricked iMac, I was able to clear 100Gb of storage. Now I'm sitting with close to 220Gb available but I've not turned the thing back on. Not sure what I'd do until theres a dot1 release. No reply either from Apple Support despite two attempts.
Still amazed - and candidly, angry - that this is the first install to fail. This level of support or failure isn't something I've seen from Apple, ever.
I have these versions too in my 'Purchase History' I did post some hints on where 'Sierra' might be found but it appears that I have been a bad boy and my post has been deleted. All I can say to you is 'Seek and ye shall find' - The truth is out there.
