1. Generating disk label files

• Download the latest OpenCore Package and unzip it
• Inside the OpenCore folder you will find /Utilities/disklabel
• Run Terminal
• Enter cd and hit Space
• Drag the "disklabel" folder into the terminal window and hit Enter to change to this directory.
• Next, enter the following command (replace the text in the quotes "" ):

   sudo ./disklabel -e "YOUR DISK LABEL" .disk_label .disk_label_2x

• Hit Enter again

The disk label files will be stored in the "disklabel" folder but they are hidden.

2. Moving the files to the correct location

• In Finder, press CMDShift. to reveal hidden files:

• Go to Misc/PickerAttributes and click on "Select" (or just add 2 to the current value)
• Check box "OC_ATTR_USE_DISK_LABEL_FILE":
