 ## Note about macOS build situation
 
-These macOS build files on GIMP repo do not fully support older macOS yet.
-You can use them only the latest 3 versions of macOS.
+These build files on GIMP repo are the recommended to build on macOS.
 
-The build files for older macOS are in: [gimp-macos-build]
+The legacy build files are in: [gimp-macos-build]
