I'm currently looking to add USB 3 to my Mac Pro 2012 5,1 (dual booted with 10.8.5 and 10.14.6). The original suggested
Sonnet Allegro Pro USB 3.0 PCIe (USB3-PRO-4PM-E) that gives 5GB/s per port with 4 controllers looks great, but is discontinued and I can't find one second hand. The new
Sonnet Allegro Pro Type-A USB 3.2 PCIe Gen 2 (USB3-PRO-4P10-E) has the ASMedia3142 chip and Sonnet said it would not be compatible with any version of OSX earlier than 10.12.6. Sonnet
does have the
Allegro Type-A USB 3.2 PCIe 4-Port (USB3-4PM-E) which has the Fresco Logic FL1100 chip and is said to work with OSX 10.8.2+. This seems to be my only viable option for the Sonnet cards.
However, Inatek makes the
RedComets U21 /
RedComets U22 / and the one I really like is the
8-Port Power Supply USB 3.2 Gen 2 PCIe KU8212 which they
claim works with Windows 7+ and Mac OSX 10.8.2+. The Chip in these looks like ASM3142.
-Why would Sonnet say the USB3-PRO-4P10-E with ASMedia3142 is 10.12.6+ only if Inatek is claiming 10.8.2+ support with the same chip?
-Does anyone here have experience using The U21/U22 or KU8212 cards on OSX 10.8? or even the Sonnet USB3-PRO-4P10-E card?
I've checked the
Definitive Mac Pro Upgrade Guide, and it's a great resource but these cards don't seem to be listed. Any help appreciated.
