How to partition a hard drive on macOS
Today we're covering the easiest way to partition a hard drive on macOS. These steps will work on both internal hard drives and external devices like USB drives. Partitioning is useful for things like virtual machines or dual boot rigs. But it can also be a useful troubleshooting tool.
Partitioning involves splitting a hard drive into individually usable chunks. The capacity of the hard drive is split between the partitions, not shared. So a 100GB hard drive can make two 50GB partitions. But the split doesn't have to be even. You can specify any amount you need. One partition can be 22Gb while the other is 78GB.
