756 Do the Sonnet USB 2.0 or USB 3 cards support the Apple SuperDrive?Apr-02-22
933 What versions of macOS support Allegro USB 3 cards?Apr-02-22
All Sonnet Allegro (and Fusion Dual 2.5" SSD RAID) PCIe Cards use a macOS pre-installed driver.

These cards are compatible with macOS 10.10 in the MacPro 3,1; 4,1 & 5,1 and in Thunderbolt 2 Expansion chassis.

These cards are not compatible with macOS 10.11, due to a bug in the Apple driver.

These cards are compatible with macOS 10.12 (2)-10.14 in the MacPro 5,1 and in Thunderbolt 2 & 3 Expansion chassis.

These cards are compatible with macOS 10.15-macOS 12 in the 2019 Mac Pro and in Thunderbolt 2 & 3 Expansion chassis.
-------------------------------------------------------------------------------------------------------------------------
Notes:

- These cards are not compatible with Thunderbolt 1 expansion chassis.

- macOS 10.12 erroneously reports a 5Gbps connection when connected at 10Gbps.

- The maximum Apple-supported OS for the Mac Pro 3,1 and 4,1 is OS X 10.11. Dosdude1 offers patchers to allow installation of newer versions of macOS. The Apple USB 3 driver in these patched newer versions will support the Allegro cards.

- Performance of the Allegro cards may be limited by the Mac Pro 5,1 PCIe 2.0 bandwidth.
