macOS TeamCity Build Agent won't upgrade

Question

I have just setup TeamCity for the first time, and am trying to connect a macOS Build Agent so I can use the Xcode Project build step. However, after installing the agent on a Mac, it connects to my server, I authorised it but it just keeps getting stuck trying to upgrade.

See the logs below:

Upgrade call received from the build server
Will upgrade when become idle

It isn't doing anything else, but just seems to be stuck on waiting to become 'idle' forever.

Answer 1

After being left 'idle' for around 40 minutes, the process started and finished a few minutes later.

So the solution for this is to just be patient!
