There[SQ]s no official Instagram Messenger app specifically for macOS (Mac computers). While you can access Instagram and its direct messaging (DM) features through a web browser on your Mac, there isn[SQ]t a dedicated desktop application like there is for Windows or mobile devices.

Therefore, "IG : dm Instagram Messenger for Mac" doesn[SQ]t refer to an actual existing app. Any app claiming to be that is likely unofficial, potentially untrusted, and possibly malicious. It[SQ]s best to stick to using Instagram[SQ]s website in a browser on your Mac for DMs.
