Envoy Port View


  • The Envoy is designed to receive all needed power through the USB cable, therefore a separate power adapter is not necessary.
  • For the safe removal of your drive and to assure that no data is lost, always eject or unmount the drive from your operating system before powering off.

Device Setup

SSD Compatibility

  • The OWC Envoy is compatible ONLY with the original Apple SSD from the MacBook Air. Any other third-party SSDs, including OWC SSDs, are NOT compatible.
  • The Envoy for MacBook Air 2010–2011 works ONLY with the Apple SSD from those specific models.
  • The Envoy for MacBook Air 2012 works ONLY with the Apple SSD from that specific model.

NOTE: The pictures shown in these instructions use the Envoy for MacBook Air 2010–2011. The assembly process is identical for the 2012 version, except the black SATA connector is slightly wider.

2.1 Assembly

1. Turn the Envoy enclosure upside down, as shown below. Note that the two included screws are different lengths. For now, set these screws aside.

Envoy Assembly guide

2. Remove the bottom cover. The circuit board will be slightly loose; when fully assembled the board is held in place by pegs on the bottom cover.

3. Insert the Apple SSD into the black SATA connector on the circuit board, as shown below. The connector is notched so that only one orientation can be used.

4. Reseat the bottom cover, then use 4 a Torx T5 driver to install the two screws mentioned in Step 1. The longer screw goes on the left, the shorter screw goes on the right. Avoid over-tightening the screws, as they may strip.

5. Remove the backing on each of the adhesive rubber feet and place the sticky side of each foot into one of the grooves on either end of the Envoy, as shown.

The assembly process is now complete.

3.2 About Data Backup

To ensure that your files are protected and to prevent data loss, we strongly suggest that you keep two copies of your data: one copy on in your OWC Envoy and a second copy on your internal drive or another storage medium, such as an optical backup, or on a second external storage unit. Any data loss or corruption while using the Envoy is the sole responsibility of the user, and under no circumstances may OWC, its parents, partners, and affiliates be held liable for loss of the use of data including compensation of any kind or recovery of the data.

3.3 Troubleshooting

Begin your troubleshooting by verifying that the USB cable is properly plugged into the computer and the Envoy. If the Envoy is still not working properly, try a different USB cable. You can also connect it to a different USB port or a different computer. If problems persist, contact OWC Technical Support (see below).
