I am trying to connect my xbox to my iMac using a Thunderbolt HDMI adapter. One end is an HDMI port, which I plugged my xbox HDMI cord into and then I plugged the Thunderbolt into my computer
- The Xbox works on a TV using an HDMI cord.
- Early 2013 iMac
- macOS Mojave 10.14.2
- AmazonBasic mini DP to HDMI
However, when I press Command F2, nothing happens. It just makes a sound like its saying "no" or whatever, like the incorrect sound.
Is there another way to go into Target Display or is there a program that I need to actually view the screen on my Mac?
Target Display Mode just isn't popping up, so I've already tried it. What else can I do?

The short answer is no, since the DisplayPort to HDMI adapter is one way. You will need an active adapter to ingest the HDMI and output (mini) Display-port if Apples documentation is wrong. Your model is listed as only supporting thunderbolt in, but sometimes undocumented things work (like extra ram or refresh rates more than advertised.)
This is mostly explained in the Apple documentation on target mode display where you have to feed it an actual thunderbolt signal or an actual DisplayPort signal.
Everything else points to this working if you got a different adapter, but I’d be sure you can return the active adapter if you can’t confirm it will work before buying. They are around $100 for good quality adapters and maybe $45 for the lesser expensive. Shop carefully, the A to B direction is crucial as you now see; as is whether you have an active or passive adapter.
