Installing Xcode 15 on CI bot hangs and times out #133461
Description
We had a couple of bots upgraded to macOS 13 so we could test Xcode 15 on them - one devicelab bot and one chromium bot.
When installing Xcode on the chromium bot, it gives this error and then hangs and eventually times out:

I don't think that's the real issue, though. I looked at the mac_toolchain code and getting that error shouldn't be fatal, it should continue on to try and accept the license. However, mac_toolchain doesn't provide enough logs to figure out where it's getting stuck.

Just a guess, but perhaps it's getting stuck waiting for the license to be accepted because it's using sudo and waiting for a password to be inputted?
Also, the flutter devicelab bot works fine and had no issues installing Xcode 15.
