If you've been using your Mac for months before deciding you need a Boot Camp partition, you may find it's too late. When you run the Boot Camp Assistant, it may tell you that you have too many 'large files' on the system for Boot Camp to create a partition.

One solution found on the interwebs is to use iDefrag to defrag your computer. I am not a fan of this, as I am on a budget :). As an alternative, try these steps:

  1. Open up Disk Utility.
  2. Navigate to the Partitions tab.
  3. Shrink your primary partition by the amount of space you want your Boot Camp partition to take up. NOTE: You may need to do this in two or three tries, as Disk Utility may throw an error if you try to resize by too large an amount. I had to do it in three small increments.
  4. Now that the partition has shrunk, expand the partition so it covers the rest of the disk, or as much space as you would like.
  5. Run Boot Camp Assistant. Everything should now run smoothly.
This method worked for me, after tinkering for an hour or so trying out different solutions.
