[ChrisRackauckas]

This was solved in #521 and the hotfix has already been sent to Pkg.

Maybe we should get CI running on apple silicon (or some other ARM CPU)?

# The architecture of the Julia binaries.
#
# Please note that installing aarch64 binaries only makes sense on self-hosted aarch64 runners.
# We currently don't run test builds on that architecture, so we cannot guarantee that the input won't break randomly,
# although there is no reason why it would.

What does it take to run on a self-hosted runner?

[ChrisRackauckas]

Maybe. We usually avoid that kind of complication unless the library is actually architecture-specific, since there's no reason to hundreds of extra tests if it's just normal Julia code. LinearSolve is started to get a bit borderline though with its BLAS defaulting.

[ViralBShah]

Apple silicon is in macos-latest on github actions now.
