Hey guys, so I tried partitioning my mac with Boot Camp, but got that NFTS error message that the partition was too big. So I quit the windows install and went back to osx to remove the partition and make it smaller, but now I'm getting the Startup disk cannot be partitioned message. I'm not incredibly tech savvy, so I'm not really sure how to fix it, but I don't want a partition being reserved for windows that i cant actually use. So can anyone give me like a manual how to fix it haha, I'd really appreciate it.And be gentle, I'm not a mac genius haha. Thanks!

You're not the only one.

From what I understand, it means that your drive is most likely fragmented. I am going to assume you understand the basic principles of fragmentation, but if you don't, Wikipedia can explain it quite well. Because all of your files are fragmented, there are several bits of important system files (kernel, various system processes, etc.) that can't be moved at all without damaging the system during a partitioning. As a result, it can't partition it.

There are two ways to go about this. The first is to buy a defragmenting software, like iDefrag (I recommend this) or Disk Warrior, or to clone your drive to another disk, do a reformat of the disk in your Mac, partition it there, and clone it back.
