@kgpai it seems that it get's oom killed on the 8-core runner... https://github.com/facebookincubator/velox/actions/runs/19209491808/job/54909575235?pr=15447#step:10:2309 I'll try and lower number of parallel jobs, or we can use a bigger runner.

The switch to macos 15 requires us to update the deployment target to 15. That mean the wheels will not install on lower macos versions. The only way around this is to build the dependencies we use from brew locally with the correct deployment target:
