Cursor disappears from external monitor on 10.13.4 update

Same issue here after 10.13.4 update

A little bit more details though, based on what I've read here and there, in case it could help :

• Issue occurs on :
  • MacBook Pro 13-inch 2017, Two Thunderbolt 3 ports
  • External monitor :
  • connected through USB-C > HDMI
  • 1920*1080 @60Hz
  • rotation : 90° (works fine only when set to "standard rotation")
  • Magic Mouse 2 connected since 10.13.3
• What I've tried to fix the issue :
  • make the mouse pointer bigger : works, but not the best solution for me
  • rotate my screen to standard rotation : works, but not the best solution for me
  • reset SMC and PRAM : fail
  • set Mirror Mode ON then OFF : temporarily works, then pointer disappears again when using Safari/Finder/Mail(...)
  • try the other USB-C port : fail
  • install 10.13.4 combo update : fail
• Other info :
  • The mouse shaking feedback works (cursor is displayed since its size is not the default size)
  • Cursor actually works (but, well, being invisible, it's useless)

• Other fix attempts :
  • change screen resolutions and refresh rate : fail
  • flash plugin uninstall : fail
• Other info:

  tested on a different HDMI screen (same resolution and refresh rate though) : exact same issue

There's actually a thread talking specifically about the hidden mouse pointer issue on external rotated screen.

Seems that we have pinpointed the issue here 🙂. We will have to wait for a fix then...

I'm confirming this same issue with a nearly identical setup and attempted fixes.

Issue occurs on :

• Started with recent update to High Sierra 10.13.4 (as soon as I restarted for the update the problem was immediate)
• MacBook Pro 13-inch 2017, Two Thunderbolt 3 ports
• External monitor :
• connected through USB-C > HDMI
• 1920*1200 @60Hz (Asus PA248q)
• rotation : 90°

Like Pierre, increasing the mouse size via the Accessibility window in system preferences is a temporary solution but as soon as you scale the mouse to low it will disappear again. I tried rotating my monitor display to "standard" and can confirm that allows you to view the mouse on the external monitor at the mouse's normal size. Again, changing back to 90 degrees rotation will make it disappear again. Mirroring displays works until you go into a finder window then it disappears again. Resetting SMC and PRAM doesn't it solve it either.

Until a solution is found I will have to live with a larger cursor size. It's the only work around that I know of.

Thanks Pierre for being thorough

Oh my god... yes making the cursor bigger helps. But it have to stay that way.

That is just stupid. I have this problem since the last update.

Apple support just suggest to turn the resoultion down and bam you now can see a small part of the cursor...

I'm having the exact same issue since upgrading to 10.13.4 on a 2017 13-inch MacBook Pro.

Most suggestions that I can find online do not help alleviate the issue:

- increasing cursor size - Nope

- reset PRAM - Nope

As I realized it only happens when I hook it up to my LG 5K monitor (as recommended and sold on apple.com), which is set to a higher scaled resolution, I tried setting the resolution to the default recommended resolution. Lo and behold, it fixes the problem!

I'm not entirely happy with the fix though as I am used to the higher resolution on the 5K monitor and now things look gigantic. I also could use a little more screen real estate.

Hope Apple could fix this issue soon.

I also would like to add that it happens to me rather consistently when I am coding on Sublime Text 3 and Atom. It does not happen on apps like Safari, Finder or Slack.

Edit: It seems that it generally occurs to rotated screens, I would like to add that mine is not rotated. I'm using the 5K monitor in landscape mode.

Hi, It seems like its a system. A workaround that worked for me is to make the cursor larger by going into System Preferences -> Accessibility -> Display -> Cursor size

You might need different cursor size for different resolution

I guess we will have to wait for a new update until then...

I have had the same issue, it only occurs when my two external displays rotation are turned either 90 or 270 degrees and also disappers in certain editors (ATOM etc)

only fix ive found is to increase the cursor size to a rediculous size

Hi, Apple support contacted me recently regarding this issue. After many tests and reports, they confirmed that this is an OS issue and that they are aware of it and are working on it...we now have to wait for a High Sierra update then (they weren't able to give an ETA though).

Same here with a MacBook Pro 2017 but the cursor only disappears on the third screen! Can't find a way to fix it. Bummer!

forgot to say that problem happened after having updated to 10.13.5 beta and that my 2 external screens are Apple Displays

Same issues on MacOS to 10.13.4

On Macbook pro 13-in 2017. Very annoying.

Accessibility display changing the cursor size works for me but agreed that this is not a good solution.

I'm having keyboard issues too...

Do you have the bug number from when you reported it?
