CL 212101 has a comment from Dec 19 2019 that included darwin-amd64-10_8 in a slowbot request. darwin-amd64-10_8 is not a builder type that we support. currently has the darwin-amd64-10_8 build for 8+ hr in waiting_for_machine state:


coordinator should probably do something better than attempt to wait for a machine that we know will never become available.

I'm not sure if this is a general feature that needs to be implemented, or if there's something specific regarding darwin builder versions and perhaps this issue affects only darwin-amd64-10_8.

darwin-amd64-10_8 is not a builder type that we support.

It's listed at, so technically we do support it. Or at least that's what the code thinks.

Remember we maintain old builder images so we can still test older supported releases of Go. (But 10.8 is so old we can drop support for it: Go 1.12 is our oldest supported release and it requires macOS 10.10+:

But if macOS 10.8 were still supported, the reason darwin-amd64-10_8 takes forever to spawn is because of the TODO in cmd/makemac (#35698).

In this case, we just need to delete it from the builder config map.
