I have an early 2015 13 in rMBP running macOS 10.13.2.

I am trying to set up a bootcamp partition for windows 10, but every time I run the installer I get the following error message:

Your disk could not be partitioned
An error occurred while partitioning the disk. Please run Disk Utility to check and fix the error.

Running first aid on my hard drive does not return any errors. I also get the same error whether I have file vault turn on or off. I found a forum post somewhere else that thought Time Machine snapshots were responsible and suggested a terminal code to delete existing snapshots but that didn't work.

Please let me know what additional diagnostic information I need to provide

Thank you and happy holidays!

I had this as well. The only way to correct it for me was to restart my Mac and boot from recovery and then check the disk.

When that was done I was able to install windows 10. If that fails. All I can suggest is to reformat the drive and start a fresh. Might be over kill but it could sort out whats wrong.

I tried running first aid from the recovery mode; still no errors. Restarted and tried boot camp again with the same results. Thank you for the tip =( I'm hoping to avoid having to reformat the drive.
