BEST ANSWER: I'd imagine so, it's more about wether you have the appropriate output connectors on the computer but it should work just fine.

Will this adapter provide sound out for a macbook pro (2009)? My present adapter does not, and online it generally says that this mac's minidisplay adapter does not output sound. If not, what is the appropriate adapter or one that will work?

BEST ANSWER: I’m 90% sure that in the 2010 models Apple introduced Sound output through the mini display port. So use a different cable 1/8 inch to do sound and maybe a mini display to vga for the Video.

what is the difference between 12795 and 12742, other than size, price and DP 1.2a. I have a couple of the other 12742 ones in white and I really do like the slim new design. both are passive so I guess one could be certified higher?
Last time I was here I picked up one of the active ones and it didn't work with all of my devices, not always detected, reduced resolution output.

It works
I got this to use with a Macbook. The previous adapter worked, but somehow creates interference that killed the wifi when it was active. I got this adapter as a replacement with the hope that it wouldn't have the same issue (it does).
4 stars for being a perfectly serviceable adapter
-1 star for requiring a loop of aluminum foil so the wifi still works when I use it

Cable worked perfectly and well packaged
As always, Monoprice quality and service. The cable comes in a resealable study bag which is a nice bonus. Connection was sound and cable is sturdy.

Works as expected
It works as expected; transfers the sound; I've used this to connect different computers (Mini displayport) with Ubuntu 16.04 and 18.04 installed to my large TV (HDMI) successfully.
The mini display slightly protrudes but I can still connect USB thumb drives to the USB slot that is next to my mini displayport on my laptop.
At its most 'thickest' the plastic around the mini displayport is 11mm wide and 8mm high.
At its most 'thickest' the plastic around the HDMI side is 26mm wide and 14mm high.
