In this article, I will guide you to create a Mac OS Extended (Journaled) partition with GParted. In this case, you can use other tools instead of Disk Utility. Disk Utility will report MediaKit reports not enough space on device for requested operation. This error occurs because the partitions created do not comply with Apple’s partition policy.

To start, find a USB drive that is big enough (8 GB should work) and erase it using Disk Utility. It wasn’t immediately obvious to me how to do that, so I wrote the steps down if you’re looking to do the same.
