I am reviewing only the Mac compatibility, not Windows. It may work out just fine for Windows but I don't have Win boxes to try it on.
I purchased this because it was the first USB 3.0 card with Mac compatibility. After installation the driver just would not install. The "install" button was greyed-out, which has been observed by others on the forums.
Then I tried downloading it from the maker's web site. It installs fine, but destabilized my system. I'm running OS X 10.6.6 on a new 2010 Quad core Mac Pro with no other 3rd party drivers installed.
The problem with the driver, and I give full blame to the driver authors not the hardware maker, is that it is a custom "hack" of the standard USB driver from Apple. That's right, they replace the Apple driver with their customized one. So, among other things, this means you can't take the latest OS X updates from Apple until you check with these guys to make sure they are ready first. It's the old Windows driver problem brought to Mac. Ick.

Just do your research. They may rewrite the driver or otherwise do something to make Mac compatibility less risky. But at the time of this writing I have returned mine and won't be going the 3rd party USB 3.0 route.

I recently bought this Caldigit USB 3 PCI card for my 2009 Mac Pro. The speed when connecting a Mac drive is very, very impressive. On a few spot checks, I'm seeing up to 80 Mb/sec copying from a 5400 rpm external USB3 drive to an internal 7200 rpm drive. I then tried connecting an NTFS formatted USB 3 drive to a Windows 7 VM running under Parallels 7. I got a hard crash of OS X, with the reset picture showing up right away and the screen freezing.

I do want the faster USB3 speed under Windows. I heard that Parallels 8 supports USB3, so I bit the bullet and upgraded to Parallels 8. After the upgrade, my Windows 7 virtual machine was updated with the Parallels 8 drivers. I then had to shut down the virtual machine, and I went into the configuration dialog and turned on USB3. When I turned on USB3, Parallels presented a dialog informing me that the proper USB3 drivers might not be present in my virtual machine, and included a link for downloading the needed drivers. I downloaded those drivers, and then rebooted the VM and installed the drivers. Windows 7 immediately recognized the "new" hardware, and said that the drivers were installed successfully.

I then tried my NTFS USB3 drive again. Success! I'm getting superb transfer rates, far beyond what I can get under USB2, with excellent stability of both the VM and the Mac.

If you're using Parallels and you want to take full advantage of the speed of USB3, then it's really worth upgrading to Parallels 8.

If you're using a Mac Pro running 10.6, then I can attest that this Caldigit USB3 card will work extremely well for you!

Hi. I just installed my CalDigit USB3 PCI card in a Mac Pro. I had purchased a USB3 Hub at the same time. During installation, the computer would not re-boot. After a bit of time with a very helpful tech at Caldigit, he learned I had a hub connected and indicated that hubs do not currently (9/4/12) work with the card. He also advised that the Apple keyboard cannot be connected to the card. Per his info, the card works well with most external hard drives and that has been their focus. Also works with USB3 card readers.

I had just read an article/review saying that CalDigit had just opened up their support on this card to work with all devices on the OS X side with a new driver. I have been having nothing but failure getting USB 3 to work on a Mac with Lion so I bit the bullet and bought the card (July 2012).

Upon installation under Windows 7 64-bit, Windows immediately recognized the card as the NEC USB 3.0 and automatically installed Windows drivers. My USB 3 drives (Western Digital 1 TB Passport and a PRORaid JBOD array) immediately started working - beautiful - but not unique as I have gotten other cards to do this.

The big test was rebooting into Mac OS X Lion and seeing what happened. With no drivers, no USB 3 drives recognized - normal. I put in the CalDigit driver disk and ran the USB 3.0 driver install disk. There were separate installer files for the last 3 versions of OS X but I ran the one for 10.7 (Lion). During the install you get a warning that the drivers will only work with a CalDigit USB 3.0 card (but the card will work with just about anybody's devices - unlike some other companies that only support their own brands or drives, etc.)

A reboot was required and then ..... everything worked. And the speed was great. About 15% faster than for my eSATA card. (Other USB 3.0 cards were at or slower than my eSATA card.)

So, I do not know how this card used to work, or how it may work on other computers, but right now it is doing A-OK on my dual boot 2012 12-CPU MacPro (20 GB RAM, 9 TB disk space, with 512GB SSD).

One warning - not so much on this card but with the state of USB 3.0 on some Macs and OS X.
