      2. After the screws are removed, flip the enclosure over and lay it right-side up. Remove the cover by lifting up neat the LED and sliding it away from the USB port.

      3. Carefully align the drive at a slight angle into the board connection and slide it forwards until fully seated.

      4. Once the drive is fully seated use the included drive screw and Torx T5 driver to secure the drive.

      5. If the SSD does not have a heat sink, install the thermal pad on the inside of the cover. If you SSD has a pre-installed heat sink, no thermal pad is needed

      • NOTE: The thermal pad corner should be aligned with a corner notch engraved on the inside of the cover. Positioning is important to ensure proper thermal dissipation.

        6. Place the cover back on the OWC Envoy Pro 1A starting with the LED side and laying down towards the USB port. Secure the cover using the (2) removed case screws form earlier using a Torx T5 driver.

        7. Once the case screws have been secured, add the included rubber foot in the notch housing the case screws.

        8. Connect the included USB cable into OWC Envoy Pro 1A and into a system. The LED will illuminate a solid white.

        3.2 Usage Notes

        • The Envoy Pro 1A is designed to work with select Apple SSDs from most 2013 to 2019 Mac models. It is also compatible with Aura Pro X2, Aura Pro X, Aura N2, and Aura N drives. However, there are customers who own Aura X2 drives and other 3rd party drives with heatsinks. The heatsink doesn't allow for the Envoy Pro 1A cover to be applied because of the added height.
          • Users can use the Envoy Pro 1A with drives that have a heatsink however, the cover will need to remain off. Prolonged Envoy Pro 1A use without the cover is not recommended due to debris exposure and potential fall damage. NOTE: Removing the heat sink to apply the Envoy Pro 1A cover is not supported and may void the drive manufacture warranty. Removal of the heat sink once applied to the Aura Pro X series of drives will void the warranty. Do not recommend or instruct for the removal of an applied heat sink.
