Summary

  • Add Intel Mac (x86_64) support for the desktop app
  • FFmpeg sidecar now downloads x86_64 binaries alongside ARM64
  • Whisper uses CPU-only mode on Intel Macs (Metal GPU not supported)
  • Parakeet V2 is filtered out on Intel (CoreML model crashes with SIGFPE)
  • Added architecture logging for debugging

Changes

Component Change
FFmpeg Download x86_64 binaries from evermeet.cx for Intel Macs
Whisper Force use_gpu(false) on x86_64 to avoid Metal error -6
Parakeet Add apple_silicon_only flag, filter V2 on Intel
Logging Add architecture info to Parakeet sidecar logs

Test plan

  • Build and run on Intel Mac (MacBook Pro 16,1)
  • Verify all Whisper models work (CPU mode)
  • Verify Parakeet V3 works
  • Verify Parakeet V2 is hidden on Intel (would crash)
  • Verify ARM64 builds still work (no regressions)

Notes

Parakeet V2's CoreML model causes a SIGFPE (floating point exception) in Espresso::general_padding_kernel_cpu when running on Intel Macs. This appears to be due to ARM64-specific compilation of the CoreML model. V3 works fine on both architectures.

The pnpm-workspace.yaml was missing the required `packages` field, causing
pnpm commands to fail with "packages field missing or empty" error. This
fix adds the root package to the workspace configuration.

Also includes Cargo.lock sync for version 1.11.2.

Intel Macs now work with all Whisper models and Parakeet V3.
Parakeet V2 is hidden on Intel due to incompatible CoreML compilation.
