Mac stuck on loading bar

Worst update released. Can't even boot up, so I can't finish my university coursework! Thanks Apple for harrassing me to install this terrible update that has caused more than myself the same problem. Pathetic.

My MacBook Pro is exactly the same, working fine yesterday now it’s stuck on loading bar. I had to take it in last time there was an update to reinstall is system.

It seems obvious to me the updates are the issue here

High Sierra has bricked my laptop.

I had my computer in sleep mode. Opened it back up and it was on the Disk Utility screen for no reason. Repairing the Disk did nothing. Resetting SRAM and Pram did nothing. Time Machine can't be found. Finally decided to reinstall the OS in spite of probably losing all my files, which froze. Upon restart, I can no longer install the OS, something about the server being unreachable. I tried a hard reset, and now the progress bar shows up, loads very slowly and gets stuck at 100%.

Apple needs to fix this. For free. I did nothing to warrant this. Never had these kinds of problems before. Your update fried my drive. There needs to be a reckoning with customers, because this is totally unacceptable.

Same issue over here. I updated back in December though and went to the frozen at 100% today when I did a restart... unless somehow Apple snuck in to do their 10.13.3 update while I was restarting, I am not sure why it would randomly start doing this. No back up since I wasn’t supposed to be updating... lost it all. 😕

I had this exact problem and and don’t know a fix however you don’t have to loose all your data if you haven’t got a time machine back up

I got a TB external drive and cloned my Mac hard drive onto it by booting into recovery mode and using disk utility

I was then able to retrieve all my files from another Mac

How is it that so many people have the same problem my computer was fine until High Sierra! I cant tell if my reinstall is done or if again i am sitting with a fully loaded progress bar. Chat told me to wait 3 hours and if no movement try reinstall AGAIN! Wow LOL

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.

Im scare what i do to my macbook will make my macbook became worse 😭

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).

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.

Hi, I tried these two sets of commands as suggested, unfortunately, did not work.

thanks for sharing this and giving us hope. I am cognisant of the fact that hope is not a strategy - so going to reformat my drive and go back to an older time machine back up.

Responding to an earlier post, I do not think Apple cares about us.

Take care.

Alerady sent to switch and they said motherbord problem and then cant fix it since macbook mid 2012 sparepare obsolate. And then didnt format for me too. 😓

I wonder if motherboard problem, macbook still can turn on?

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.

I've been working with this problem more over the past week and came across what I think was the actual root cause to my problem. Don't know how this applies to anybody else, but was causing issues for me.

LONG STORY SHORT: Unplug anything extra you have connected to the computer (USB drives, external hard drives, etc.). For me it was an external hard drive that may be going bad that caused the problem.

Full story:

Since I thought it might have been something I installed that corrupted my system, I wanted to start from a clean slate before setting up anymore software. So I tried using one of my external hard drives to create a USB bootable drive for High Sierra so I could startup to that drive to macOS Utilities, erase my hard drive via Disk Utility, and then reinstall High Sierra from scratch.

I created the bootable drive, and then when trying to boot into it, macOS Utilities never loads! I then read a tip online about unplugging all peripherals and so I unplugged everything and tried to boot into recovery mode again, and this time it loads up no problem. So that indicated to me that the drive might be a problem. I got a separate USB flash drive and turned that into my external bootable drive, booted up into recovery mode no problem, and proceeded with the process of wiping my hard drive and reinstalling the OS again.

That was all successful. I decided to plug in all of my USB stuff again, everything came up, and then I shut down. Booting back up - SAME PROBLEM WITH THE PROGRESS BAR!!!

So I unplugged everything again and then tried to boot, and it came up no problem. I now have all my USB stuff plugged in with the exception of that one hard drive, and now after several reboots, everything is fine and dandy. So it's either the drive going bad, or according to my friend at Apple, a bad driver, controller, or firmware. Either way, running without this one drive attached is working fine for me, so if you have any peripherals connected, it could be an issue with how the computer is reading that device. This goes for USB devices, or anything plugged into any of the other ports. If you have something going into a port other than power, unplug it and see what happens!

Same here. Stuck on progress bar at 100% after software updated while the machine was sleeping. Been like this for four days. Had 10 calls to Apple. Tried safe mode, restore mode, first aid, saving files to external hard drive then reinstalling OS on the MacBook. Nothing works! So frustrating and I’ve lost days and days of work as a self employed person. Not at all happy.
