Cause (Documented platform behavior): Homebrew supports Apple Silicon only in its installer; Intel macOS configurations are Tier 3.
Fix status: documented_behavior
Limitations:
- When this abort was added is unknown; older installer versions supported Intel.
- Note: under Rosetta 2, `uname -m` reports x86_64 as well.
Unknowns:
- Whether existing Intel installations keep receiving bottles.

solution · Revision 1
Proposed fix: [Homebrew installer] 'Homebrew on macOS is only supported on Apple Silicon processors!' — current install.sh aborts on Intel Macs (Intel is Tier 3)
Recommended action: Use Apple Silicon runners/hosts; on Intel use an existing /usr/local installation or a manual/alternative install at your own risk (Tier 3), or MacPorts.
