Mac stuck on loading bar

Same problem here.

It happen to me since this morning. I tot only me have this problem, then i try search and found this.

Anyone have any idea how to solve this issue?

I try reinstall too many time and still stuck at 100% loading bar then i have to force shut down.

If it's a corrupted drive, sometimes the only thing that can be done is to reformat the entire drive and not just the boot partition. It happens occasionally with any drive, but mostly if there was some sort of improper shutdown, such as a frozen OS that's forced to power down.

It's best to have some sort of backup to recover quickly if it does happen.

I faced the same issue. I recovered by formatting the boot disk and reinstalling the high Sierra OS. It’s highly recommended that your hard disk is partitioned and all your important data is stored in non-boot partitions.

Hey man, I had the exact same problem. Took mine to my local Apple store and they fixed it. They turned my macbook into an external hard drive through their system and backed all my files up. They then reformatted my macbook and uploaded from my back up but they put my OS to Sierra. High Sierra is the problem! The chap in the store basically said stick with Sierra for a while and only go to High Sierra if you want. You will not get charged by Apple as the issue is software not mechanical. I know this doesn’t help you right now but it might get you back on track for the future.

Same thing happened to me after following the steps on this forum. Next day the problem returned. I ended up resetting the PRAM, whatever that is. I found how to do it on a site I think was called "OXIS.com", or something like that. I used the wife's computer to google for the fix. So far, its working well. Good luck.

My iMac was stuck on the black progress bar screen after the recent macOSHighSiera update. I went into Find iPhone on my phone and clicked play sound. It loaded the login screen a few seconds later.

I just fixed half an hour ago with restoring from time machine backup in my Late 2012 MBP. High Sierra.

As someone who managed to recover from the "Stuck Progress Bar" malfunction by using TM, may I suggest you have a look at "Mafrom's" reply of the 28 February as probably the only solution to your problem. I "restored" back to a December 17 backup and lost all the work I had done from then to March 17th. However, I had carried out a March backup, three days before the malfunction and I can now copy the missing files individually from this back up. (I wanted to avoid a possible problem which may have been saved the March backup.)

Accessing your hard drive from another mac and copy files to it would seem to be the only solution to recover your work.

There is a possibility if a machine has Internet Recovery available. It’s possible to boot from an external drive and to use Internet Recovery to install the OS on an external drive. There have been a few posts about iMacs here, and they can be really tricky to try and pull out the drive. Then even if the internal drive is corrupted, it still might be possible to repair it or at least try to access data even if the internal drive won’t boot.

You’re the first person I’m aware of who’s reported a relapse. I’d make certain that any available Mac OS updates have been installed. Someone else suggests resetting the PRAM. (Restart, hold down option-command-p-r, allowing the Mac to chime three to five times, then let go of the keys.)

Sorry, but I don’t have a better idea at this time. Good luck!

I’ve recently had this problem and was on the phone to Apple Support twice, told to try reinstalling the MacOS which ended up taking over 3 hours. Nothing worked.

So in recovery mode I decided to try running “First Aid” on the internal Macintosh HD disk in the “Disk Utility” section and that seems like it’s worked for now. Really not impressed with it all tbh and this is the first major problem i’ve had with my MacBook Pro in 4 years.

Start up in safe mode

To start up in safe mode:

1. Start or restart your Mac, then immediately press and hold the Shift key. The Apple logo appears on your display. If you don't see the Apple logo, learn what to do.
2. Release the Shift key when you see the login window. If your startup disk is encrypted with FileVault, you might be asked to log in twice: once to unlock the startup disk, and again to log in to the Finder.

To leave safe mode, restart your Mac without pressing any keys during startup.

If an issue doesn't happen in safe mode

If an issue doesn't happen when your Mac is started in safe mode, try restarting without pressing any keys.

• If the issue comes back, you might have incompatible login items.
• If the issue doesn't come back, it was probably caused by a cache or directory issue with your startup disk, which safe mode fixed.

Use safe mode to isolate issues with your Mac

I had the same issue last Friday on my iMac 2017 (including the "too many corpses" message on Verbose mode).

I couldn't boot up the iMac, neither regularly or in safe mode. Both ways the progress bar reached 100% after long minutes and nothing happened.

There was no way to recover the OS. The only way was to format the hard drive (which, by the way, was fine on Disk Utility).

I backed up my files connecting an external hard drive and typing some commands on Terminal.

Very disappointed with this iMac. It has always been slow on boot. I have many Bluetooth problems (my keyboard and mouse disconnects at least 2 times a day, and I have to plug a wired mouse and keyboard to force a restart in order to keep my opened files without loosing data).

Hi PrasadYR,

There is no way other than formatting the internal hard disk and installing the os again.

Restore using time machine backup it will work.

It work for me.

That's how my mac went down in the first place, via the update. When I reset the PRAM it loaded the update like nothing ever happened. So far, so good. Knock on wood, or whatever.

Could you elaborate for me how to recover your files using the method you mention. I’ve tried to use disk utility and cannot see how to access files.

Even if the drive is corrupted, it might be possible to use the "Restore" function in Disk Utility to copy data to another drive. It's poorly named; a better name would be "Copy" or "Clone" because that's what it does. If there's an internal SATA drive, then it's possible to remove the drive and then place it in an external "enclosure" to try and access whatever data can be found.

Disk Utility only operates on entire volumes. It doesn't allow for direct file/folder access like Finder does. However, there are numerous ways to access folders/files even with a damaged volume.
