If you have previously partitioned your Mac's hard drive in order to download a macOS beta or install Windows, but now you need that storage space back, you can remove the partition and recapture the much-needed space. Here's how.
Getting rid of a secondary partition on the Mac is a two-step process. After erasing a partition, you can then remove it from your system.
Before you start
The most important thing to do before making any changes to your hard drive is to back it up. Time Machine has the easiest way to back up your data if you don't already have a system in place.
