Why can't I partition my SSD or external hard drive on macOS?

Category : Setup / Operation
To partition a drive on macOS, you must first format it as either APFS or Mac OS Extended. This is because the Disk Utility on MacOS only supports partitioning operations on these formats.

Note:
●Formatting Limitation: Formatting a drive as APFS or Mac OS Extended can only be executed on a MacOS computer. Windows computers cannot format drives to these macOS-specific file systems.
●Warning: Formatting will erase all data on the drive. Please ensure you have backed up any important data before formatting.

By following these steps, you should be able to partition your drive on macOS. If you encounter further issues, consider contacting Apple Support or seeking professional technical assistance.
