Mouse pointer disappears on second monitor.

10.7.3 didn't fix it for me either. Every time I update the system, I have a small spark of hope only to be let down again.

BTW: I use my main 24" monitor for my CAD drawing window and the second 24" montir holds the many paletts of tools and resources (filling about 2/3 of the screen). Because of this, I'm constantly moving the cursor between the two monitors. It's VERY frustrating to have this problem constantly interupting my work.

Hello All,

I'm having the same problem. I notice if I vigorously click and move the mouse around it will reappear. NOT CoOL! I've looked on some different forum and seen where this problem has been accruing since 2008. For me it has not been any particular application the mouse will disappear, but I did fist notice it in FCPX. It does look like they don't care to resolve this If this problem has truly been around since 2008. I hope to be made wrong. ;-).

Yes! I agree that it has something to do with Silverlight/Netflix. It also happens to me when editing my blog within the Shortcode Exec PHP panel. When I click in the shortcode editor, I frequenly lose the mouse pointer for all of my screens. To get it back, I have to click on the upper OSX menu bar at the top of the main screen.

Same problem, BUT, I've noticed if I leave a usb mouse and keyboard plugged in, my bluetooth magic track-pad works fine (cursor doesn't disappear, pad doesn't randomly disconnect) and the bluetooth keyboard stays connected vs. its usual random disconnectedness. The magic mouse however continues to drop out whenever it feels like it and when connected, behaves erratically at best.

This has been such a pain.

I have the same problem from time to time, MacBook Pro 13-inch mid-2010 connected to an external monitor.

I know it's not a fix, but if I disconnect the monitor and then reconnect it, that usually resolves the situation. Although I have to stick all my windows back to where I like them again...

Hi Jowie,

As dlbogdan mentioned earlier, moving the cursor to the dock makes it reappear. Does that not work for you?

I hope Apple does somthing about this. It's very surprising to me that this problem has not been adressed. This happens to me several times a day interupting my workflow and causing frustration. It's very unlike Apple to let such an important interface issue persist.

Hi PanzerCAD,

No this doesn't work for me. I don't know if it matters that my MacBook's screen is set up as the second monitor, but also includes the dock... The system menu bar is on the main screen (external monitor) because it sits above my MacBook screen.

Jowie,

I think your problem may be caused by a separate issue - but I could be wrong. Nevertheless, having to disconnet and reconnect the monitor is a painful way to get it back. Hopefully we'll all get a fix for this...

This is my setup as well and this works for me, too. I also make extensive use of Spaces and have Air Display adding an old MacBook Pro to the desktop, but that doesn't seem to have caused it. Just clicking to another app totally works for me, though. Anoying, but not a huge problem.

I know how to REPRODUCE this issue. I have a Chrome window open on my laptop screen, maximized to the max. On my external monitor I have a non-maximized Terminal window open. If I focus on the Chrome window, then focus on the Terminal window and start scrolling up and down for a bit, then move the mouse back to my laptop monitor, the mouse cursor will disappear and I will have to do a click in order to get the mouse cursor back.

I can't reproduce it this way 100% of the time, but there are periods of a few minutes when this behaviour does happen consistently.

I get this all the time. Sometimes randomly, others are reproducable.

I can reproduce it every time by playing a movie in iTunes in fullscreen mode. The second fullscreen is activated, the mouse disappears (making it near impossible to access the hover controls at the bottom of the movie). After exiting fullscreen, the mouse does not return until I command+tab(hold) and move the mouse while the app icons are up on the screen.

It's ridiculous this hasn't been fixed yet.

I'm getting the same problem on a MacPro with two Apple monitors connected. All the Apple Lion updates applied. Cursor disappears randomly on the second monitor, I click on the task switcher to get it back. Very irritating bug.

Does anyone think Apple monitor these discussions?

Or care?

We've been seeing this for some time now and can confirm that it does remain unfixed in the 10.7.4 update. Apple... I don't know about you but having a cursor is fundamental and vital to working on a desktop. During the course of an average work day, it disappears approximately a dozen times. We reset it by clicking on the secondary display and voila... it's back.

Perhaps you can address this immediately as it is affecting many of your users on a daily basis?!

It's a very frustrating bug. It happens 30 or 40 times a day to me :/ I'm adept at fixing it (place cursor over the icon bar) - but I'd just rather it didn't happen!

I can't believe how long this bug has been around without a fix!
