OS X reinstall says: 'Unable to unmount volume for repair' tonymacx86.com. Started Mac using this drive (Press Option key after sound when starting up and select the High Sierra boot disk). Opened Terminal and unmounted using - diskutil unmountDisk force /dev/disk2 (use diskutil list to find your drive). When it restarts and I go to boot into OS X, it brings up the loading screen for a bit and then the installation files, citing 'MacOs unable to unmount volume for repair'. I have no idea why this is happening, since the installation is still being run off of the bootable USB - which volume is it trying to unmount?

I have got a 21.5 iMac past due 2013 that boots from an exterior SSD. Acquired no issues setting up Sierra but today when I try out to install High Sierra it provides the sticking with mistake: “MacOS could not be set up on your computer. Incapable to unmount voIume for repair” Initial time improving with the exterior SSD so I believe this is definitely user mistake but not sure how to proceed about fixing this problem. What I possess tried: Uninstalled the instaIler and downloaded clean. Unmounted the internal push HDD before operating the installer.Upgrade: I tried something to try out and more separate the concern.

I connected my SSD tó my MacBook Air fixed it as the boot attempted to run the installer and nevertheless obtained the exact same error. When I went to eject thé SSD after résetting the boot travel to the MacBook internal SSD(I rebooted after doing this) I got message stating the commute could not be thrown because some programs may be making use of it. I feel supposing that simply because quickly as I connect this SSD in some background procedure starts up and starts making use of it for some cause but possess no idea what it is. I are using a 500GN Samsung Capital t5 by the way. Hoping somebody can assist out with a suggestion as I anticipated this to proceed much smoother like my MacBook Professional upgrade proceeded to go lol. I have the exact same problem.

Mine will be an internal SSD. I contacted Apple but they have not been recently capable to solve the issue yet. I have attempted: Uninstalling the installer and down loaded fresh edition. I possess made an external boot disc to operate the High Sierra from. I have got operate the High Sierra in Safe Mode. Run First Help which functions and passes when logged into my Macintosh but not when in macOS Recuperation. When in macOS Recovery using Port I have got forced an unmounted the Push but doesn'capital t make a distinction.

I hope someone discovers a answer shortly. I lastly maintained to upgrade to Great Siera. After trying many various strategies to unmount the internal drive, this is certainly what finally worked -.Make sure you possess a Time Machine Back-up before performing this! I produced an external USB Great Sierra shoe disk. Started Mac making use of this commute (Push Option key after audio when starting upward and select the Higher Sierra shoe storage). Opened Port and unmounted making use of - diskutil unmountDisk force /dev/storage2 (make use of diskutil listing to find your get). I then opened Storage Power and ran Very first Aid on the unmounted commute, (It worked well and handed) I then removed the unmounted storage.

I after that mounted the removed disk. Next I closed Disk Power and ran the High Sierra installer choice.There were a several thinking restarts when the installer was running. Lastly, I selected my Time Machine back-up when the installer questioned and it began moving my data files and applications. It required ages but everything is certainly back to regular. Hope this assists anyone else possess the same problems.

Developing upon previous answers, I have got determined that the issue will be because the installer can be glitched and can't convert the commute to APFS. This issue can effortlessly be circumvented: 1. Boot to internet recovery or a USB commute with the High Sierra Installer (standard Sierra recuperation mode received't perform). Go to Drive Application and attach your Mac pc volume.

Close Disk Energy and move to the command line terminal. Perform diskutil umount pressure /Quantities/Macintosh HD/ Get be aware of your disk id. Disc1 in my situation. Run diskutil apfs transform /dev/cd disk1s1 (replace disc1 with your storage identification if needed) 6. Once this is performed, reboot and Higher Sierra can be set up from either a USB commute or Web Recovery mode (option+command+R).

Recently, I have got been getting weird issues setting up Sierra to my recently made partition. It generally ended up with a NASTY error message saying that it could not unmount the voIume for repair (whát repair, anyway?). At the initial, I thought the volume has been unclean, so I bootéd to my operating Un Capitan again and acquired formatted the partition once again. It nevertheless failed. After that, I believed it had been the fact that I has been making use of the installer in El Capitan to set up it to the new partition.

So, I developed an set up USB. The issue surprisingly made an appearance! The problem: The problem I believe was credited to the createinstallmedia tool. If the USB will be in truth created with that tool, the installer divides the set up procedure into two. First, it copies the set up files to thé HDD partition (thát component creates problem), and after that it reboots fróm that partition tó set up the files and ultimately create the Recovery partition. The issue is that it for some reasons tries to unmount thé partition it offers booted from, which will be obviously not possible; hence, it neglects.

The basic problem most likely has very much to do with the dividers construction. In my situation, I used MiniTools Partition Manager to migrate my Windows installation fróm my HDD to thé brand-new SSD travel. It could possess been owing to that, aIthough MSR partition is definitely also recognized to trigger issues in some circumstances.

The partition structure has been as foIlow:. ESP = EFI Partitión. MSR = Microsoft Réserved (culprit, too?). Gain10 = Home windows travel. Sierra = New partition developed for Sierra. Macs HD = Un Capitan drive (currently set up and functioning).

RecoveryHD = El Capitan recuperation push. The solution: Make use of the 'Restore BaseSystem.dmg' technique to make the installation USB. Adhere to these tips:.

I presume that you have down loaded the installation from Macintosh App Shop. If therefore, then right click on on the document, click 'Present Contents Packages'. Click on on 'SharedSupport'.

You should see InstallESD.dmg. Increase click on on that document to mount it. Open up the Operating-system A Install ESD partition. Make certain that concealed files visible (there are many methods, use Google). Best click on BaseSystem.dmg and click on open up to mount it.

Open up Disk Utility. Put in your USB commute. Click on 'Partition' and produce too dividers. One with 200MB and the various other one with whatever dimension you wish. The 200MC partition format should be MS-DOS (Body fat) and provide it CLOVER as name. The 2nd one't format should end up being OS Back button Extended (journaled) and give it USB as name.

And click ' Apply' to structure the USB. Of training course, everything on that travel will end up being wrecked. It'beds needless to state that you shouId backup its items first. While still inside Disk Power app, click on the second partition (it's should become named USB). On the standing bar, click on on ' Edit' and choose ' Restore'.

You should find ' Restore from: OS Back button Install ESD' click on on ' Operating-system Back button Install ESD' and select ' Operating-system X Bottom System' from the dropdown menu. Now click on ' Restore'. You might need your password to complete this task. If so, kind it in and click ok then wait. Upon finition, smartly unmount OS X Bottom System disk under ' Disk Pictures' in Cd disk Utility. Open the USB push (the title ' USB' will turn out to be ' Operating-system X Bottom System', that's why you need to smartly unmount the various other one making use of Disk Utility to prevent dilemma.). Inside the USB get, move to ' System' after that ' Installation' get rid of the document named ' Deals'.

That'beds actually an allias (ór a shórtcut if you would like). Proceed to Operating-system Back button Install ESD push. Duplicate ' Packages' folder from now there and insert it in your USB/Program/Installation. The exact same way, duplicate the other documents from Operating-system X Install ESD drive to the origin of your USB (the basic, not really inside a foIder on thé USB get). You require to typically copy the subsequent files: AppleDiagnostics.chunklist, AppIeDiagnostics.dmg, BaseSystem.chunkIist, BaseSystem.dmg. lnstall Clover to thé first partition of your USB push named CLOVER (unless named in any other case).

Reboot from the USB drive and everything should move easy and without this error. This should also function for Chameleon bootIoader. You might óf course not require to create two dividers in this case. You should probably not directly enhance from Un Capitan to avoid this problem.
