My Cloud: macOS Slow Transfer Performance with Private Shares

Description

Data transfer to and from a Private Share is slow when using macOS 10.11.5 and higher.
This happens when macOS SMB2 Signing is turned on. (default=on)
SMB2 Signing allows more secure sign ins.

Resolution

Turn off SMB2 Signing.

Critical: Turning off SMB Signing is a security risk. Check with a third-party IT Security company or network admin for help. Western Digital does not provide security analysis and cannot recommend a third-party security company.
