3 years ago Looks like the brew update step adds 4-5 minutes to the runtime of the macOS CIs, not terrible given they are run delayed / adhoc by Cirrus anyways. If that's acceptable then this PR could be mergable. The failure is in a Linux build that is not touched here.
One other thing I noticed, is that even though we're installinggcc@9, I'm pretty sure that Apple Clang (which is gcc on macOS) is being used for the builds.

3 years ago @fanquake Pretty sure it's using GCC, see https://cirrus-ci.com/task/5799658971725824:
+ gcc-9 -v
Using built-in specs.

Given an older base image is being used, this can avoid instances where package installs fail, due to brew trying to use no-longer existent download locations.
Will see how long the update step takes, although a few minutes extra time spent in the macOS CI is probably less of an issue here. If it seems too long, I think moving to the Big Sur image would also be fine.
