Before you start the unreal engine,
You have to have the headset on, click ALLOW data access on the in headset popup after you plug it into your computer (or connect with AIRLINK), if you don’t use AirLink connect via Oculus Link. Either way, once you’re loaded into the Oculus link (Rift) menu, you can THEN open your unreal project. If you do those things after the editor is already open the “VR preview” play button will stay gray until you restart the editor.
note, I use a PC, so idk if there are additional MAC specific issues
