Hi RW! Thanks for posting! I'm running sierra at the moment (10.12.3) and we have no problem installing apart from having to remove Blender from quarantine. If you haven't already checked to see if you are running blender in quarantine (and if you haven't you most likely are) then this post will help.

We've noticed that when blender is unzipped on some versions of MacOS X, its automatically tagged to be quarantined, even though its been digitally signed.

If that doesn't help, or you've already removed Blender from quarantine, the next thing to do would be to send us your log files. They are located in:

~/cr/logging where the "~" represents your user folder. Then you can send the log files to

info 'at' crowdrender 'dot' com 'dot' au

Also, you might want to try starting blender from the terminal and seeing if there are any error messages that are printed to the system console. If you haven't done that before, you need to open the terminal program (its in /Applications/utilities, and you can also find it using launchpad by searching for "terminal").

Once in the terminal program you need to navigate to the place where the blender.app package is, I put the contents of the unzipped blender download a folder called "Blender" in applications so on my system I would type the following at the command prompt

cd /Applications/Blender/blender.app/Contents/MacOs

and then to open blender just type

open blender

now you get a new terminal window which prints out stuff while blender runs. We use it for debugging, if something goes wrong that isn't captured by the logs (this can happen if the addon fails before logging is started), then the console window may capture this error. You can simply copy and paste the error messages into an e-mail and send the address above.

Whatever you manage to send us, we'll look into for you :D
