Also a fan of the late adoption on OS X / macOS new versions. While that works well, you can install the newer version in another partition or disk. That's what I did with macOS Sierra and then I went back to an older version as it doesn't seem very stable to me. FWIW on a macOS Sierra test box I just had compress hang on zipping up 2 small log files. Not sure if that's Sierra or if the machine has problems, but it sure was weird.
