+### Installing on OSX Sierra and El Captain ###
+
+Since version 4.0.0, DIYLC runs on Java 8 which helps with newer Mac machines, but can cause issues on older Sierra and El Captain Macs. If the OSX application bundle "diylc-4.X.Y-osx.zip" fails on Sierra and El Captain, but you can still run the multi-platform version.
