| macOS 10.14.6 supports both 512 and 4k block size SSDs, but macOS 10.13.6 supports only 4k block size SSDs. Today, most SSDs are shipped from the factory programmed with a 4k block size. If your SSDs are programmed with 512 block size, however, and you need to be compatible with macOS 10.13.6, you must reprogram your SSDs to a 4k block size. Sonnet has written a script to do this, but it needs to be run on a Linux computer. You can download the instructions here. For a copy of the script, contact support@sonnettech.com. |
