GitHub for Mac version is too old

I just downloaded the Github desktop client (from https://desktop.github.com) on my 2019 Macbook Pro laptop running the latest MacOS (Monterey 12.0.1). GitHub.app opens, but when I try to log in, it says “GitHub for Mac version is too old”. The GitHub.app about panel says “Responder Train (185) You have the latest version”. Please advise.

@stevedekorte the new version of GitHub Desktop should be called GitHub Desktop.app – it looks like you are launching the older version that is no longer supported. I would recommend going into your Applications directory and removing the old version (GitHub.app).
