Q: I have to go in to single-user mode to boot in OS X.

I don't understand, should I just change the default operating system to OS X? I do this all the time to boot in to OS X, it is the only way for me to get to OS X. I explained this process in my previous post.

First of all, the Mac doesn't try to restart in to OS X on itself. I myself click on Mac OS then Apply and OK.

Here is a full explanation of what I do to get in to OS X when my default operating system is set to Windows.

1. I boot up the computer in Windows.

2. I proceed to click on the Windows System Tray and click on the Boot Camp icon (Boot Camp Control Panel).

3. I then click on Mac OS X then Apply and OK.

4. I shut down the computer.

5. When I turn it on I go to single-user mode and type in the following commands: "/sbin/mount -uw /" and "exit".

6. A ton of codes stars to scroll down and after a few seconds I land on the desktop screen of Mac OS.

Did not work, the computer shut down when it got to 3/4 of the way on the progress bar. By the way, I don't know if I mentioned this earlier but I am running Windows 10 in Boot Camp.

If you are in OS X, click on System Preferences -> Startup Disk. Click on the lock icon, if necessary. Click on the OS X (not Bootcamp) and click on Restart. Does OS X come up properly without any further intervention by you?

No, the computer still turns off by itself when the progress bar gets to 3/4 of the way.

I have tried to re-install OS X before and I have mentioned what will happen if I try to re-install OS X in this forum. I am going to quote myself from a previous post of mine.

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.

Let us leave the OS X installation on the internal disk alone. Install a fresh copy of OS X on an external disk using Internet Recovery. You can use a USB flash drive, but it will be slow. a FW/USB2 (or USB3)/TB HDD is recommended.

 

Please see How to install OS X on an external drive connected to your Mac - Apple Support .

I am sorry to say this but are there any other ways. This seem a little bit over the top and now I don't think I mind typing in the 2 codes in single-user mode everytime I want to boot in to OS X. I have done fresh installs many times before but never on a macintosh, only on a windows machine. If there aren't any ways then I might consider doing this. I do have to wait a bit though because I borrowed my 8 GB USB stick to a friend of mine. I have a 32 GB at the moment but that has the windows 10 ISO on it. I would prefer to do it on the 32 GB USB. So I am going to wait to get the 8 GB back and make that the windows 10 ISO and then do a fresh install on the 32 GB (better capacity is better).
