Alotm HDMI to RCA Cable, 5 Feet 1.5m HDMI Male to 3-RCA Male Connector Video Audio AV Component Adapter Extractor Jacks Cord for HDTV HDTV 1080P;

HDMI to RCA cable is designed to connect and transfer (NOT CONVERT) signals from HDMI port to RCA port. 

 - This cable functions as a signal transmitter, but NOT a signal converter. As HDMI carries digital signals while RCA carries analog signals. In order for these two formats of signal to communicate with each other, both input and output devices needs to support the signal conversion function (code and decode), please kindly check with your user manual. If both input / output devices do not support signal conversion, a signal conversion box is required (sold separately). 

Even though HDMI cables support Hot Plug Detection, improper usage might result in resetting / restarting both devices, or even may cause damage to the devices. Therefore, we do not suggest Hot Plug action for any HDMI cables. Please make sure both input and output devices are off when plugging or unplugging HDMI cables.

It works as a signal transmitter, not a signal converter

Q&A：

Q: Is this an RCA TO HDMI cable? Color-coded plugs to the TV and flat-end plug to the cable box, yes? 

A:No, it's an hdmi to rca converter. In other words it's the "female" hdmi receptacle. Its an adapter that allows for an hdmi cord to plug into a tv that that does not have an hdmi input. So it might be possible for you to use this "adapter" to run an existing hdmi cable from your cable box to to an rca tv input. 

Q:can i use it to connect my mac laptop to the tv?

A: No, not without a converter like they mention in the description.
