Does this work with OS X 10.8.3 ? I bought an iWires minidisplay hdmi in Apple store 3 months,it stopped work after update to OS X 10.8.3,I lost £40.

I use iWire minidisplay hdmi connect to my new Sony KDL-40EX653 BRIVA TV, It was work except loss audio sometimes when play video on Youtube.

Last week (24/03/2013) it stopped work at all after update iMac OS X 10.8.3.Because IWire cable has been bought 3 months ago,I trusted Apple store,then bought this expensive cable,
I cannot return because it is not apple -brand product,I lost £40 pounds.I still miss my big picture on TV.I am looking to buy another brand cable.

My question is this Belkin mididisplay hdmi cable compliant with OS X 10.8.3 or not?
What is different between the Belkin cable and iWire cable ?
How long the guarantee?
