VNC Screen Sharing: White Screen

When I connect to a remote VNC client, I get the password prompt (yay) I appear to connect (yay) but then all I see is a white window instead of the remote desktop (boo).

I've simultaneously logged into the remote client with Logmein. If I move my cursor over the (totally white) screen sharing window, I can see the cursor moving on the remote client desktop. So it's connected and operational, but I can't see the display.

I previously did not have this problem. I have since made changes to the remote firewall and I've bought a new wireless router at home, so those could be factors. But like I said, it's fully functioning besides the fact I have a white screen sharing window.

Any idea why?

I had the same problem, what worked for me is setting the Screen Sharing application to run in 32-bit mode. You have to find the app first, it's buried in the System folder:

/System/Library/CoreServices/Screen Sharing.app

Get Info on the application and check the box "Open in 32-bit mode".

Some others with this problem report that this still doesn't fix things, but it worked for me!

I had exactly the same issue as the OP, too: blank white screen when logging into a known good VNC server (on CentOS 5; vncviewer and CotVNC both worked) via Screen Sharing.

The suggestion of setting /System/Library/CoreServices/Screen Sharing.app to run in 32-bit mode worked for me.

Bob nailed it. I tried setting to the 32 bit mode and it's FIXED!. Some notes: I was able to connect to our old Win 2000 server and vnc screen share just fine. Then out of nowhere it stopped working, upon launch of the screen sharing window, the screen would go white. I began troubleshooting and found that while the screen was white on the Mac, the mouse cursor still functioned on the server. I tested screen sharing to other Macs and it worked exactly as it should. After finding this article I tried the 32 bit fix.

Thank you. Thank you. Thank you. I have been trying to get past the white screen on VNC for a number of months and decided to search the community again. 32-bit mode nailed by VNC access to a VMWare Fusion XP virtual machine.

You are not speaking to Apple here. This is a User-to-User forum. I would encourage you to file a bug or feature enhancement with Apple at either:

BugReporter

Free ADC (Apple Developer Connection) account needed for BugReporter.
Anyone can get a free account at:

And/Or

That way Apple would know what you know.
