fix(release): darwin/amd64 binaries abort on macOS 26#1292
Merged
Conversation
macOS 26 dyld requires the SG_READ_ONLY flag on the __DATA_CONST
segment; without it binaries abort at launch:
dyld[66420]: __DATA_CONST segment missing SG_READ_ONLY flag
osxcross ld64 only sets the flag when the deployment target is >= 10.15
and the darwin/amd64 build defaulted to 10.9, so every amd64 release
binary is affected. arm64 already targets 11.0 and is fine; its env
line just makes the existing default explicit. Go itself requires
macOS 11+ since Go 1.23, so no supported platform is dropped.
Verified by snapshot-building both darwin targets in the release image
and checking the segment flags.

Problem
pscalecrashes at launch on macOS 26:macOS 26 dyld requires the
SG_READ_ONLYflag on the__DATA_CONSTsegment. The darwin/amd64 release binaries don't have it: osxcross defaults to a 10.9 deployment target, and ld64 only sets the flag when targeting macOS 10.15+. All amd64 release binaries are affected (including under Rosetta on Apple Silicon, e.g. via Intel Homebrew). The arm64 binaries already target 11.0 and are unaffected.Solution
Set
MACOSX_DEPLOYMENT_TARGET=11.0for the darwin builds — amd64 is the fix; arm64 already targets 11.0 and the env line just makes that explicit. Go itself requires macOS 11+ since Go 1.23, so no supported platform is dropped.Verified by snapshot-building both darwin targets in the release image and checking the Mach-O segment flags:
__DATA_CONSTnow carriesSG_READ_ONLY(0x10) andminos=11.0on both arches.
