fix: add hostArchitectures to PKG Distribution.xml to prevent Rosetta prompt#268
Conversation
… prompt The macOS PKG installer was incorrectly prompting users to install Rosetta on Apple Silicon Macs, even though all binaries are native arm64. When using productbuild with a custom Distribution.xml, macOS Installer does not auto-detect architecture support. Without the hostArchitectures attribute, it assumes Rosetta is required. Adding hostArchitectures="arm64,x86_64" to the <options> element tells macOS Installer that the package supports both architectures natively, eliminating the unnecessary Rosetta prompt on ARM Macs. This is a known issue that affected fish-shell, PowerShell, and other projects using custom Distribution.xml files. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Summary
hostArchitectures="arm64,x86_64"attribute to Distribution.xml<options>elementProblem
When installing
mcpproxy-*-darwin-arm64.pkgon an ARM Mac, macOS Installer prompts:This happens even though all binaries in the package are native arm64.
Root Cause
When using
productbuild --distributionwith a custom Distribution.xml, macOS Installer does not auto-detect architecture support. Without thehostArchitecturesattribute, it assumes Rosetta is required for compatibility.This is a known issue that affected:
Solution
Add
hostArchitectures="arm64,x86_64"to the<options>element in the Distribution.xml template. This explicitly tells macOS Installer that the package supports both architectures natively.Test plan
