Whenever I try to turn on my Mac book Pro, progress bar stops at 100% and never turns on. So kindly provide any solution so that I can access my Mac.
Specs
High Sierra
Mid 2012
4GB ram
Intel I3 processor
P.S. I have tried re-installing high Sierra , SMC reset, disk repair but nothing seems to work.

I texted a friend of mine that does software development for Apple and he was able to help me get past this problem. I was experiencing the same symptoms: upon starting my iMac, the progress bar would load underneath the Apple logo, and it would just sit there and never progress any further. Here's what helped me solve the issue without having to reformat my drive or reinstall the OS.
With the computer shut down, turn it on and hold down Command + S to launch a command shell. Give it a few minutes until it doesn't load anything else on the screen.
Type the following commands, pressing enter after each command:
mount -uw /
sync
reboot
See if this boots you back into the system. If not, try this order:
mount -uw /
mv /Library/Extensions/*.kext /
mv /Library/LaunchAgents/*.plist /
mv /Library/LaunchDaemons/*.plist /
sync
reboot
I was able to get back into my system, but I noticed if I shut down and tried to turn it back on, the problem still persisted. According to my friend at Apple, he was 99% sure it was third party software. So I uninstalled each new program I had installed recently one by one until I narrowed it down to which one I thought was causing my particular issue. My computer appears stable now, and it may be because a program I was using isn't updated for the latest High Sierra update, and the incompatibility caused something weird to happen on startup. Definitely not 100% sure that's what happened, but between using the commands above to get me back into the computer, and uninstalling things one by one and going through this process over and over until I narrowed it down, it solved it for me. Hope this helps someone else!
Hey, how exactly do I mount the disk with disk utility? I don't think that file vault is on. please help me.
I have followed these instructions. After restarting, what should the following screen look like? Will it continue to update? Or will it just go back to normal?
hello, have you had success with this situation?
Your experience is what it should be. It worked for me. And all is well. For now. No telling what will happen with future updates. Oh well. One challenge at a time.
Hi, I have followed your steps, after restarting my MacBook has gone back to the loading screen - how long should I leave this / wait to see if it has worked? Thanks!
Thank you! This worked like a charm for me, I was tearing my hair out because nothing was working!
I have a macbook pro 13 inch (late 2011) and I tried the commands in recovery mode. After entering the second command, I got the response as attached. Please help...I use my MBP for work.

I'm having the exact same issue... I also reinstalled High Sierra, first aid, etc. Not much of a techy, but unable to find an answer.
Did you end up getting ahold of Apple support? I unfortunately do not have a time machine back up either, so I hope I don't lose everything. Yikes.
Before I started trying some of these suggestions, I unplugged all of the external drives from my 4 USB ports, plus pulled the SD card out. Restarted and it is fine! So, try this first if you have anything plugged into your computer.
ThiloJD,
You just saved my life. A good 10 hrs. finding and implementing "solutions", none of which worked. Just about to search for the nuclear option, reformatting, when I found your absurdly simple solution. Boom! I'm booted up. I've no idea why that key combination works, but it worked perfectly.
Big thanks to you for posting that.
Wow! Apple's recent updates really stink. I have been resisting High Sierra because I've heard so many negative things about it, but I decided to install a 10.12.6 security update last night, and my Mac Mini (which is usually fine) hung up "stuck at the full progress bar." I tried every strategy, from safe mode to Disk Utility, but nothing has worked, so now I am backing up from Time Machine. I try to ignore the constant nagging from Apple to upgrade on my desk top and on my iPhone, and from now on I will try harder.
I was able to get my MacBook pro to start back up by starting up in recovery mode, going to the top left where the apple logo is, select start up disk, then select the disk, enter password and then click restart.
Not as of now. Although I have submitted my mac at a service center, hopefully they would resolve this issue.
