## Discussion

- (esc) - https://github.com/numba/numba/pull/10384
- Do we list all Tier 2 platforms and attempt to accurately maintain this document?
- The Q regarding `osx-64` (Intel chips, not M* series) has come up at least twice via discourse since that platform was relegated from Tier 1.
- We can merge this, but it won't be solve the problem of people trying to install on `osx-64`.
- Need an env variable to force building from source.

- PR was recently merged, a few non-breaking issues remain.
- Needs tetsing on CUDA
- Needs check of icelake vs. saphire-rappids
