There are a whole bunch of questions about very slow performance of VNC when using it to login to a Mac. Among them:

  1. More specifically, I'm looking for VNC server software(s) that would run on both 68K and PowerPC. What VNC server software is available for Mac OS? Just to clarify: this question is about Mac OS, not Mac OS X or macOS (Sierra/High Sierra).
  2. Then navigate to /Library/vnc/vncagent and select the Open button: and then click the lock icon again. Instant Support App is downloaded from the internet. Starting with Mac OS 10.15 you must specifically allow Instant Support to be opened on install as it is downloaded from the internet. Select open to allow the application to run.
  3. The address looks like vnc://IPAddress or vnc://Name.Domain. On your Mac, do one of the following: Connect using the name: Click the Finder icon in the Dock to open a Finder window. In the Locations section of the sidebar, click Network, double-click the Mac you want to share, then click Share Screen.



I had the problem also. I've gotten around it, as described below. Vmware tools for os x sierra.


First, my situation:

  • Near computer (the one I'm sitting at): iMac 20'. Native screen res: 1680 x 1050. (2007 vintage) Running 10.11.1 El Capitan
  • Far computer (the one I'm trying to see by VNC): Mac Pro with 24-inch Cinema display. Native screen res: 1920 x 1200 (early 2009) Running 10.11.1 El Capitan
  • Connection: VPN from home to work over Junos Pulse Secure. Ping shows an average round-trip time of 24 ms.
  • Using: Native VNC built into OS X: Finder: Go: Connect to Server.. vnc://[remoteMacAddress]. Running in 'Full Screen' mode with 'Adaptive Quality'.

With the native setup, I figure I was getting about 1 sec from clicking on something to seeing the change on my screen.


My workaround:

  1. On the far computer, open System Preferences / Displays. Change Resolution from 'Default for display' to 'Scaled'. In the list below, select: 1600 x 1000. This change alone got me most of the improvement I see.
  2. In the 'Screen Sharing' menu on the near computer, under 'View, uncheck 'Turn Scaling On'. This may have gotten me a bit more performance, but it's hard to tell.

Note: I think the key is, in step 1, to select a resolution that is Smaller than the native resolution of the near computer's display. Turning Scaling off just simplifies the situation a bit more.
