    I have a headless MacMini that I control by my MacBookPro. Yesterday I updated both machines to 10.13.4.

    Now, when screen sharing, frequently the pointer disappears on the shared screen, particularly when some window is in full screen mode on the Mini.

    The only solution is to quit screen sharing and start sharing again. Then the pointer appears.

    That's a bad situation. Anybody with a similar problem and a fix?

    I could limit the possible reasons for the ScreenSharing issue:

    1) It doesn't seem to be located at the server side, because on a separate screen connected directly, the pointer works fine when moves from the client machine.

    2) The issue its on the client's screenSharing. The pointer always disappears in the screen sharing window, when I resize the window. Then the pointer os only visible outside of the screen sharing window, but not inside (even though on a direct screen I can see the pointer moving normally.

    3) On the client I also cannot customise the screen sharing toolbar. It just doesn't work.

    My conclusion, the screen sharing app on the client has a glitch after the 10.13.4 update.

    Yes, I have a similar setup and I'm experiencing the same problem.

    I typically keep the screen sharing client running full time on my Macbook Pro, in full screen mode. After updating both the Mac mini and the Macbook Pro to 10.13.4, this results in losing the cursor when it should be somewhere on the Mac mini screen, within the screen sharing client. I can fix this by pushing the cursor all the way to the top of the Macbook Pro screen, getting the menu bar to drop down, and the taking the screen sharing client out of full screen mode. This behavior is repeatable.

    I updated my MacBook Pro to 10.13.4 yesterday. I use screen sharing to access a headless 2008 Mac Pro running 10.11.6... and now screen sharing will NOT connect. I can ssh via terminal into the Mac Pro, but screen sharing isn't working now... and nothing has been changed on the Mac Pro. Very frustrating.

    After connecting over SSH to the Mac Pro, I discovered that it had applied a security update yesterday AND there was a NEW remote desktop update. Applied it, rebooted the Mac Pro and I'm now able to connect normally over VNC/Screen Sharing.

    Right. Imo this problem is related to the management of the screen sharing window size on the client. When the cursor disappears, I can make it visible again by toggling between some view options of the screen sharing menu. That makes permanently restarting screen sharing unnecessary.

    Try installing TeamViewer on the mini. Setup for unattended access. Install Teamviewer on your Mac and enter the ID and PW for the mini.

    Teamviewer is free for personal use.

    This could be a solution, thanks. I assume that's as save as using Apple's own solution.

    But I still don't understand how and why Apple broke the essential function of screen sharing.

    I've got an old Mac Pro (2008) running ElCapitan that I can't connect to anymore. Did you figure out the issue?

    I also have this problem. I have a 2017 iMac and a Mac Mini both running 10.13.4. (The Mini has a monitor connected to it.) The problem happens when I try to access the Mini's screen from the iMac, but it works fine in the other direction.

    I have this problem as well. The cursor disappears and screen stops updating as soon as I maximize the windows.

    The error seems to be when you connect to a non retina mac from a retina mac.

    Here is the work around to maximize screen sharing:
    change resolution on on client mac to non retina
    maximize screen share
    change resolution back to retina
