macOS: lower deployment floor to macOS 11 (Big Sur) - #1162
Merged
Conversation
The build targeted macOS 15, which needlessly excluded every Intel Mac and anyone not on the latest OS. macOS 11 is the first Apple Silicon release and the current Steam client minimum, so it's a sensible floor that widens hardware reach for the universal (x86_64 + arm64) build. - Drop MACOSX_VERSION_MIN and the build scripts' DEPLOY default from 15.0 to 11.0; all third-party deps are rebuilt from source for the 11.0 target. - Declare LSMinimumSystemVersion in Info.plist (substituted from DEPLOY) so the floor is enforced with a clear message, not just the Mach-O minos. - Fix metakit's clean build, exposed by rebuilding deps from scratch: its Makefile invokes $(RANLIB) but never defines it, and make has no built-in default (unlike AR), so the archive step ran a bare "libmk4.a" and failed. Pass AR=ar RANLIB=ranlib to metakit's make. - Sign the app inside-out (not --deep) so the ad-hoc seal is valid, fixing local Steam builds that Gatekeeper otherwise rejected as "damaged".
