Encrypting USB devices on Macs

It is a requirement of WBS' GDPR preparation that all USB memory sticks and drives are encrypted.

As Mac devices are unmanaged by us you will need to start this process yourself. Please contact the WBS Helpdesk (help@wbs.ac.uk) if you have any problems with these instructions.

  1. Plug in the USB storage device
  2. Open Finder and click View > Show All Devices

    Open finder. Click View and Show All Devices

  3. Select the Format and Scheme as below. You can name the memory stick anything that is meaningful to you
    Select Mac OS Extended Journaled and GUID Partition Map

  4. Open Finder. Ctrl + Click on the device in the sidebar. Select 'Encrypt' from the pop-up menu

    Locate the device in Finder. Control Click and select Encrypt
