Apologies if I have gotten this in the wrong place. It's been a long few days.

Model Identifier: MacBookPro11,4 System Version: macOS 10.13.4 (17E199)

So a while back, I decided to install windows on bootcamp. I did it, and then I needed to reinstall, so I wiped it and began to do it again. It's been an absolute disaster.

First, I've tried like 100 different things. I tried boot camp assistant, it says > The startup disk does not have enough space to be partitioned.

You must have at least 40 GB of free space available.

This is clearly false since I have 103 gb available. Moreover, I have turned off time machine and deleted old snapshots as every single website has told me. I was thinking maybe I need to defrag, but apparently, defragging doesn't do anything on an SSD, which I believe I have.

Never mind, I thought, I'll try to repair everything on disk utility. Did nothing.

Tried to partition using disk utility. I created a partition called "windows" under MS-DOS (FAT) and gave it 58 gb. This is the maximum size that I'm allowed to drag the circle (which makes no sense since I should have 103 gb left, but whatever). When I did this, I received the following information (Freezing on "Applying changes to “APPLE SSD SM0256G Media”"):

I also would like to note a few other things: 1: I have been trying to do this for a while. I even got bootcamp like halfway through (disk image accepted and everything) and then it seemed to stop working sending me on a long path to figure out how to delete the useless partition 2: My mac has been running a bit slowly recently (like when I restart, it spends a ton of time with just a little bit of the bar not loaded) 3: I spilled coffee on my computer a while back, but nothing seemed particularly wrong for quite some time - I highly suspect that this is NOT the issue. 4: If you need any more information please let me know 5: I have an entire hard drive full of backups, so if I need to I can completely reformat. However, I'm not sure exactly how licenses and stuff carry over.

Thank you for your help in advance

  • I figured out how to solve the problem. Apparently, it was an issue with time machine, but I was just using the wrong string of code. I called apple and they gave it to me. Unfortunately, I can't remember the exact string, but I'll post it if I can find it. I may delete the post just so there's no more confusion though. – Talos Potential Jun 4 '18 at 3:28
