Product Manual

You may install fewer than eight SSDs now and add more later without needing to reformat existing ones. Only 2280 (80mm — the most common length) length M.2 SSDs are supported. M.2 SSDs longer or shorter than 80mm don’t fit.
Only in a 2023 Mac Pro (M2 Ultra), the initial release of macOS 14 (Sonoma) does not properly access the data in the M.2 8x4 PCIe Card. Users with macOS 13 installed should not update to macOS 14 at this time. We expect Apple to fix this anomaly in an update. (The data will not be lost, just inaccessible.) The card will continue to work fine under macOS 14 in an Intel Mac Pro, or with any Mac using a Thunderbolt expansion system.
