Subject: My Mac laptop/desktop will not pass audio or video correctly through the AT-HDR-M2C
If you are having an issue with passing your Apple laptop through the AT-HDR-M2C, such as losing audio or having a scrambled image, you could be experiencing an HDCP issue. One way to test this is to use a different PC(Windows or Linux based) and see if there are similar issues. If the issue is only related to the Apple laptop, then please update the unit to firmware version 1.0.02.
