SOLUTION: Guys don't waste your time. I had this exact problem but I tried using command + alt + r during boot up. Hold it till you see the globe pop up and let it do its thing and that should fix the problem (at least it did for me). Then you can install without problems. Good luck!

If didnt work buy an external hard disk and connect it to your mac and go to disk utilities and go to ur old hard drive then go to restore ,if the sorce is your hard disk name so thats ok usually its macintosh hd and in the other side destination grab the new hard disk, the new hard disk is gonna erase and copy the old hard disk so you are gonna have a back up ,when it finishes go to ur old drive theb click erase it will work ,you must put it on macOS (journaled) or the first option then just do the same on the first and it will work.

Boot to the Recovery Volume (command - R on a restart or hold down the option/alt key during a restart and select Recovery Volume). Run Disk Utility Verify/Repair Disk and Repair Permissions until you get no errors. Then re-install the OS.

Easy solution is hold down command + R and get into disk utility, select the main HD and select File > "Enable journaling" but if you are like me, it was greyed out. What the issue is, you are trying to modify the drive you are currently working on which it doesn't like. You need to create a USB flash installer, then reformate the drive then reinstall. The steps are below

The download went fine but when I said install the computer got stuck in the loop, of can't install the update because "your computer file system verify or repair failed" and no matter what I did I could not get out of this loop. I tried to boot form recover, boot form USB with sierra installer, tried to repair the hard drive which gave me errors like File system check exit code is 8, I tried single user mode, I tried network recovery..... like I said I tried everything. My plan was to dig up the old spinning hard drive to restore an image form it, albeit it few months old but better than nothing. Of course I do not have a backup because I said to myself this is an SSD on a mac what could go wrong, well I learned that lesson. Bottom line what needed to happen was enable journaling of the hard drive, something that was greyed out and was impossible to do. Installing a fresh OS was also not working because the computer would say the drive is locked. Enough of the problem here is the solution.

I bought a thunderbolt cable to connect the iMac to my trusted MacBook Pro. I then installed Disk Warrior software on a MacBook pro. Then I booted the iMac while holding down the t key, which allowed the MacBook to see the iMac as an external drive. Disk Warrior scanned the iMac's hard drive, rebuilt its directory and enabled journaling. I then unmounted the iMac from the MacBook and rebooted the iMac normally, and viola, high Sierra installation proceeded and 40 minutes later I am back to normal. I am considering this post and pay back for all the help I got from searching the net for hours on this issues.

From what I know the drive is locked because somehow it was corrupted. All you need to do is rebuild it using disk warrior which fixed the issue by enabling journaling. I found the mac native disk utility not to be powerful enough to fix this problem, that's why I resorted to Disk Warrior, I am not promoting them and I am not affiliated with them, that is what I used. Let me know if I can be of any help.

If you are still under warranty of AppleCare Apple will replace the hard drive with a similar drive of the same capacity -- they will not upgrade your HD. If your warranty and AppleCare have expired you can find instructions for replacing the drive yourself at Other World Computing.

First make sure you completely erased your drive and all partitions on it using these steps: How to erase an Intel-based Mac. If everything was erased correctly but you still see a locked drive, go to Disk Utility from the Recovery screen and select your drive on the left side. Are you given an option to unlock the drive? If so, enter in the password you use to log into your Mac.

It's possibly your drive may be locked with a firmware password. Try the steps in the "How to turn off a firmware password" section of this support article: Set a firmware password on your Mac. If you have a firmware password set that you don't remember, the "If you forgot your firmware password" will tell you what to do next.

If your disk is not locked with a firmware password, try reinstalling again but this time start in Recovery using one of the key combinations in the "Other macOS installation options" section here: How to reinstall macOS. Those key combination will start up from macOS Recovery over the internet.

I have just wiped my iMac, and something must have gone wrong in the process as i cant change the boot drive by holding down option key and when i go to install reinstall macOS through macOS utilities when i select the 500GB hard drive the main one it just says "Disk is locked". Can anyone help me with this issue?

I bought a used MacBook and I wanted to do a factory recovery. I restarted and held down command + R. I went to disk utility and erased Mac OS extended journaled. I restarted and I clicked on reinstall Lion OS. when I click on the hard drive and it states Hard drive Locked, I am unable to do anything.

my mac book pro did not have the option enable journal available to select it was grey, it was there but could not select it, so i externally formatted the hard drive NTFS type, then formatted it again internally with the mac, then started the installation again and it worked (mac lion OS)

I suspect he was able to attach the drive to a Windows system to reformat it the NTFS which got rid of the damaged boot sector. Then with the drive back inside his Mac he was able to reformat the drive using either a OS install DVD the system came with (grey disk) or the retail version. The other way would be using an external bootable OS-X drive (USB, FireWire or Thunderbolt).

I've created a bootable USB thumb drive just for doing this. While slow it does get the job done. On it I have a copy of Disk Utility and the OS installer to then run to prep and install a fresh copy of the OS.

Another option would be connecting your system to the other back to back via a FireWire or Thunderbolt cable and then setting up your system in Target mode that way you would be treating your system as if it were an external HD to the other system saving the effort of pulling the drive out.

@k7004205773083 Please start a new question and give your specifics as an answer here would get lost. Give your exact machine as methods differ and there are different types of locks. The lock discussed here sounds different from yours. A photo of the locked screen really helps.

I am fully aware of all of the ways to change permissions on the drives They all have a custom permission and when I try to change it to specify a user or admin as read and write they all go back to custom, and Yes I unlocked the get info before I tried.

sometimes I wish they would fire all of the nerds that are now in place and hire back the old ones. At least they the old ones had caring about users in mind they tried to solve problems instead of creating them. The New Yosemite and Lion and Montain Lion and Mavericks have done nothing except mess with older computer users and the programs that no longer work. Now all we have are a bunch of I phone idiots walking out into the streets with their eyes glued to their %#*@ phones. Einstein said "We Cannot solve problems using the same kind of thinking we used when we created them"

Sometimes the simplest fix is the answer here. Prep up a bootable USB thumb drive. Then after booting up with it run Apples Disk Utility from the thumb drive. Select your internal drive and run repair permissions and then disk you will likely need to run it a few times. Let us know how it goes, nine out of ten times this fixes things. If not you likely have a drive that's going.

You'll need to disconnect the internal drive so it will boot up via the USB thumb drive. Then go into system prefs Startup Disk alter it to the USB drive now shutdown the system reconnect the internal and reboot that should fix it.
