OSX box has remote management enabled (AppleVNCServer) and port 5900 open. Using tightvnc/ultravnc/realvnc can't connect because of "security protocol mismatch" (don't have the exact phrase). Googling yields only to posts that say "use OSXVnc" or other remote desktop solutions.

How do I connect to apple's default remote management using Linux / Windows?


be sure to activate the VNC password: go to System Preferences / Sharing / Remote Management, press the Computer Settings... button, check the VNC Viewers may control...., and add a password there.

  • That's the catch - i wanted to use the non password, default authentication which as I learned by observing traffic it does kerberos authentication which none of popular VNC clients support. – Konrads Oct 7 '10 at 11:17

I'm successfully using Vinagre (version 3.10.2 on Linux) to connect to OS X Yosemite; I didn't need to enable the "VNC Viewers may control..." option in OS X.

  • OS X Yosemite was release in October, 4 years after the original question was asked... It does not come as a surprise that on both ends progress has been made. – HBruijn Oct 24 '14 at 20:05
  • It's still good to know that progress has been made. Q&A sites are Internet's collective memory – Konrads Oct 25 '14 at 7:38

    I posted this answer because this question was at the top of the Google results when I looked for this information. I'm well aware that the software I'm using didn't exist 4 years ago; I think it's still useful for the benefit of future people who find this via Google. – biolizard89 Oct 26 '14 at 0:29
  • The answer about Vinagre is correct on older versions, as well, at least as far back as 10.6.8 and Vinagre 3.8.3. – Lester Hightower Jan 10 '15 at 23:44

It works fine with a range of VNC clients I've tried - including VNC on my iPad and iPhone - I'd recommend you keep trying different clients or check your client and server configurations.
