Release: build macOS with the newest Xcode, drop Intel artifacts - #5
Merged
Conversation
The Homebrew LLVM attempt got past the CTAD check but died in the compile: brew's libc++ 22 collides with Apple's SDK headers (_malloc_type.h vs its own size_t). The log revealed the better answer — the image already carries Xcode 16.4, whose AppleClang is new enough. So: select the newest Xcode present and use Apple's own toolchain. Intel macOS is dropped. macos-13 tops out at an AppleClang that cannot compile this codebase, and GitHub is retiring Intel runners anyway. Intel Mac users fall back to compiling from source, which is the path the console and installer already take when no artifact matches — the graceful decline verified earlier.

Second attempt at the macOS artifact.
What happened. Homebrew LLVM cleared the CTAD check but failed in the compile — brew's libc++ 22 collides with Apple's SDK headers. The log showed the image already has Xcode 16.4, whose AppleClang is new enough, so we now select the newest Xcode present and use Apple's toolchain.
Intel macOS dropped.
macos-13tops out at an AppleClang that cannot build this codebase, and GitHub is retiring Intel runners. Intel Mac users compile from source — the fallback the console and installer already take when no artifact matches, verified earlier against a served release.Linux artifacts have been publishing successfully throughout.
