// Native launcher for the BDS2 .app — compiled to a pure arm64 Mach-O by
|
|
// mix bds.bundle.macos. A shell-script main executable has no Mach-O slices, so
|
|
// LaunchServices advertises x86_64 and offers Rosetta; a real arm64 binary makes
|
|
// the bundle unambiguously Apple Silicon.
|
|
//
|
|
// Mirrors launcher.sh: resolve <Contents>, prepend Frameworks to the dyld
|
|
// fallback path, then exec <Contents>/Resources/rel/bin/<release> start.
