Jan 10, 2016 8:52 AMby Mike Sombrio,What happens when you boot onto Safe Mode? Try safe mode if your Mac doesn't finish starting up - Apple Support
-
Jan 10, 2016 10:44 AMby DwaynXD,When I try to boot onto Safe Mode, the same thing happens when I try to boot in normal mode. I press the power button > I hold down the shift key > I hear the chime and white screen > I see the apple logo and the progress bar > the progress bar only gets to 3/4 of the way and then the computer shuts down.

Jan 10, 2016 12:24 PMby Mike Sombrio,Somethings missing from this story but for the life of me I don't know what it is. I'd suggest at the very least booting onto your Recovery partition and running Disk Utility to repair the hard drive. If that doesn't help I would try reinstalling OS X from Recovery.

Jan 10, 2016 1:03 PMby DwaynXD,I have tried both in the past when I started having this problem. The only way for me to boot in OS X right now is to go to single-user mode and type "/sbin/mount -uw /" and then "exit". So I booted in to OS X and opened Disk Utility. I ran first aid on Macintosh HD and I get "First Aid process is complete, press Done to continue." After that I tried to boot in OS X again without holding down Command + S but the same problem occur, the computer shuts down when the progress bar gets to 3/4 of the way.
I then proceed to boot in recovery mode. I click on re-install OS X. My computer's eligibility had been verified. I then sign in with my apple ID. I accepted the terms of service and it began downloading, not one second later I get a pop-up saying: "An error occurred while preparing the installation. Try running this application again." This has happened before and I did some research about it and most of it were saying that the date on your computer was wrong and you can change it in Terminal in the Recovery Partition. My date wasn't wrong but I still changed it but I got the same error message.
So right now I don't think it is a hard drive failure. Because Bootcamp is working just fine on my computer. But I think the HDD is not mounted properly for OS X to boot? I would really appreciate your help for solving this problem.

Jan 10, 2016 1:31 PMby Mike Sombrio,You can only repair your hard drive from recovery. It doesn't sound like that's what you're doing. Forgive me if I'm wrong but your post above indicates that you booted into recovery AFTER running Disk Utility. If properly repairing the hard drive doesn't work and you can't boot into Safe mode I'd suggest making an appointment and taking your mac in for service.
Have you split your Fusion drive?

Jan 10, 2016 2:29 PMby DwaynXD,Oops, sorry about that. I did boot in OS X and ran first aid on my hard drive and THEN go to recovery mode. But this time I went in to Recovery Mode and then ran first aid on Macintosh HD and I got the following message:"First Aid process has failed. If possible back up the data on this volume. Click Done to continue." I don't worry much about losing my data because I have a backup external hard drive. What I have realized as well is that there a disk image called: "Apple disk image Media." And under that image there is partition that is called:"OS X Base System."
I can't make an appointment to an Apple Store, because I live on a small island and there is no Apple Store on this island.
Can you enlighten me more on what you mean by "Have you split your fusion drive?"
So if there is no solution for this, is it safe to just keep inserting "/sbin/mount -uw /" and "exit" every time I want to boot in OS X?
Another question that I have is how could this have possibly happen? I barely use OS X, I mostly use bootcamp to play videogames. And I am always aware of what I am downloading on OS X and Windows.

Jan 10, 2016 2:39 PMby Mike Sombrio,You've mentioned using Terminal twice inputting commands that you've found on the internet, if you don't fully understand exactly what every command means you can mess up OS X. I think that's what has happened here.
I'm not familiar with Fusion technology as I don't have one so I'm going to refrain from offering advice that may make things worse. I will search and see if I can find something to help and I'll ask someone experienced with Fusion drives to help out.
SOmething is wrong, either software or hardware, and continuing to enter commands in terminal is only masking the problem. You need to get this fixed.

Jan 10, 2016 3:17 PMby DwaynXD,I have only mentioned using Terminal once, I used Terminal in the Recovery Partition to change the date, month and year. I do know what this command does. I am always responsible of what I do in Terminal and this is the only thing I have done so far and tested multiple times. I found this code on another apple support discussion. How to set system time from Terminal while booted from 10.6.3 server install disk?
And this discussion too: OSX Mavericks - "An Error occurred while preparing the installation. Try running this application again."
The other code I used and still using to boot in OS X is in single-user mode, not in terminal. And this code I have not found on the internet. This code is: "/sbin/mount -uw /". This just mounts the root device and then the other code I use is: "exit", this let's me get in to OS X. These 2 codes is what I need to do in single-user mode to boot in OS X.
I am very thankful for you to be helping me right now.

The Terminal app in recovery and in your Utilities is the same Unix terminal used in single user mode. Neither here nor there.....I asked someone familiar with Fusion technology to look at yhis thread and hopefully get you pointed in the right direction.

Yes it is about the same.
You do not quit with "exit" but with "reboot".
After typing and pressing enter on: "/sbin/mount -uw /". I have to type "exit". Here is the reason.
If I type "reboot", de computer will shut down and then turn itself on. When it turn itself on, I hear the chime, then the apple logo and progress bar appear, the progress bar gets to 3/4 of the way and then the computer shuts down by itself.
If I type "exit", de computer will just get in to OS X right away.
Sorry for the late response. In summary I just don't want to insert "/sbin/mount -uw /" and "exit" every time I want to go in to OS X. I hope you can help me with this because it has been like this for almost a month now and I haven't found a single solution yet.
