I'm trying to get remote screen access to my Raspberry Pi (running raspbian) with a Mac OS X client.

Here's what I've got:

• I ran 'raspbian-config' and used it to enable the VNC server.

• The desktop on the raspberry-pi shows that VNC server is running. ps says it's vncserver-x11-core.

• The raspberry pi shows up as a shared screen on my Mac in the Finder.

• When I click the "Share Screen" button on the Mac, I get a dialog with this error message:

   The software on the remote computer appears to be
   incompatible with this version of Screen Sharing.
  

My Mac is running 10.9 (Mavericks?), so it's a bit old...

What are my options?

• Is there a config option on the pi that I can tweak? That's my preferred approach.
• Failing that, will switching to tightvncserver help?
• It feels like a bit of overkill to update my Mac for this problem, but would it help?
