This should have been fixed by https://github.com/bazelbuild/bazel/commit/231270c67d5aa771462245531fa9b2ee7d3d0ae8, you're definitely on 0.25.2? It definitely appears to be in that tag https://github.com/bazelbuild/bazel/blob/0.25.2/tools/osx/xcode_locator.m#L181-L188

you're definitely on 0.25.2?

FYI, I'm using bazelbuild/tap/bazel: stable 0.25.2.

[keith]

Can you try with the current 0.26.0 RC build? Found here https://releases.bazel.build/0.26.0/rc12/index.html
