macOS emacs Universal Binary

emacs osx Universal binary 

lipo -arch almost pointless; tried it on the emacs Universal Binary only reduced the size by 4MB.  Not worth it.  

 man lipo

lipo -archs Emacs.app/Contents/MacOS/Emacs

 

lipo -remove x86_64 Emacs.app/Contents/MacOS/Emacs -output Emacs.app/Contents/MacOS/Emacs2
