I have an early 2009 iMac, the USB is 12mbs so I'm guessing it is USB 2, with this USB 3 unit work with my computer?

I have USB 3.0 on my iMac, so I don't know if the drive will work with your computer.

It will not work for iMac's. Due to it being a DIMM, iMacs require SO-DIMM, iMac models use unbuffered RAM, non-parity, PC3-10600, 204-pin, and 1333 megahertz (MHz) DDR3 SDRAM.

I believe there has been a software update that allows this drive to work with older iMacs too. I have this drive for the Macbook Air. When I bought it in mid 2011 it was made very clear by Apple that it only works with the certain Apple products such as the MBA. When the Superdrive in my early 2010 iMac 27" died, I plugged the USB Superdrive in just to see what happens. It works perfectly as a Superdrive for my iMac.

If you have the new iMac (late 2012), you have USB 3.0 ports on it. You can hook up this HUB to your iMac, but you need the external power as well.

I use it for my MBP and it works great and was priced right. It shouldn't matter what MBP/ iMac you have.

Works great with a couple of iMacs with 10.9.4 (current as of this answer).

I really don't know how an IMac works with this product, I have a hp and the product works fantastic for me!

I use it with my MacBook Pro OSX Mavericks - works great. Not USB 3, that would be better.

it should work with a USB 2.0. to figure out if it is a 2 or 3 you have to go to the control panel and look for the ports. right click on the port you are using and click properties. if your computer is more than a year old chances are it is a USB 2.0. the difference between the two is speed of transfer with 3.0 being faster.

USB 3.0 interfaces "should" work with USB 2.0 devices. Best to check with http://support.apple.com/

If it's just a usb it should work with an iMac. I had to return this keyboard 3 times because the illumination button and several other keys did not work. So I would personally not recommend this product if you are not okay with risking the chance and losing a lot of your time. I ed ed up just getting another keyboard

I really don't know about Mac operating systems but I would assume if your Mac is USB 2.0 and/or 3.0 compatible then I would assume it would work. You will probably have to format it to match your system's file format.

When I bought this hub, I had no USB 3. Recently I bought a PCI-E card to provide USB 3. It does NOT work if I boot from a drive that has OS X 10.5.8, but it works fine with my OS X 10.10.5 (Yosemite).

Pretty sure all the iMacs that use DDR3 require SO-DIMMs, not full-size memory. Here's a link to Apple which seems to suggest this memory won't work. http://support.apple.com/kb/HT5523

I am using it with my four or five year old MacBook Pro, no problem. Even though I haven't tried it with iMac, I can't think of a reason why it wouldn't work with it. The USB connection will fit just fine.

I got my iMac in December 2011, so I'm fairly sure it's also only running USB2, and I've had no problems running this drive. I can't imagine you should have any difficulty. Especially since it's such an easy drive to set up.
