(NOTICE: currently images for this article are unavailable, but the information can be followed as described to make a determination on your drive type. We apologize for the inconvenience as we attempt to resolve this issue. Please contact our customer service department for additional assistance.)

Relevant Part Number: OWCMAU3ENPRPCI

Please note that the SSDs which Apple supplied with some of its computers are not compatible with the OWC Envoy Pro (OWCMAU3ENPRPCI). They work only when installed in the Mac model(s) they were designed for. At the time of this writing the only machines potentially affected will be the MacBook Air 7,2 | MacBook Pro 11,4 | MacBook Pro 11,5 | MacBookPro12,1 — these computers ship with SSDs that may not be compatible with any OWC Envoy Pro (PCIe) enclosure.

To check if your Apple SSD is an NVMe-based drive (any brand), follow these steps:

  1. Hold down the Option key then access the Apple menu and choose 'System Information...'
  2. Select the 'NVMExpress' item and check to see if the top of the window shows an 'APPLE SSD.' If it does you have an PCIe NVMe drive, which will not work with this specific enclosure. 

    If your computer does not have an NVMe drive, you will see a screen that looks like the screenshot below. In this case continue to the next set of steps below.


To check if your Apple SSD is an AHCI drive, follow these steps:

  1. Hold down the Option key then access the Apple menu and choose 'System Information...'
  2. Click the 'SATA/SATA Express' item, then check for the SSD Controller item at the top of the window. When you select it, additional information will appear; next to 'Description' item you will see 'AHCI Version....' 

    Depending on which brand of AHCI drive you have, and depending on when you purchased the Envoy Pro enclosure, your drive may be incompatible with the enclosure. Specifically, Toshiba AHCI drives that are paired with Envoy Pro PCIe enclosures from prior to January 1, 2018, may not work. 

    The only way to verify whether you have a Toshiba drive vs. another brand like Samsung, is to remove the drive and check to see if a manufacturer is listed on the drive itself. If the drive says 'Samsung' or 'SanDisk' it should work as expected with the Envoy Pro. If the drive says 'Toshiba' on one or more of the chipsets or flash modules, there is a good chance the drive will not work with the Envoy Pro enclosure, if it was purchased prior to January 1, 2018. 

    While we don't have examples of every possible combination of NVMe or AHCI Apple SSD at this time, we have provided some examples below so you have an idea of what to look for. If you need further assistance with the process of identifying the drive, please contact our award-winning support team
