Mouse cursor disappears.

Interesting. When I had major mouse and other problems on Lion (see my post on 4 Sept), most of the mouse ones were when using Safari when typing into Apple Discussions (but seldom elsewhere). Now I am on M.Lion, the problem has occurred just once, and in the same way.

Since installing Mountain Lion I have had the cursor disappear about once a day -- with no clear connection to any action. Often it disappears when the computer has gone to sleep. I rarely use Safari, so I doubt that the problem is connected to Safari. I have never had this problem on an Apple computer in the past six years of using several computers. I am currently using a Mac mini purchased about four months ago.

I havent found a fix yet for this problem, and it sounds like it's something that needs to be addressed with a software update by either Apple or Adobe, but figured out a workaround. Clicking with the invisible cursor onto the Photoshop menu bar on top brings the cursor back.

Hi,

I have the same issue.

As a workaround, I find out that switching user (without logging out the current user) makes the mouse cursor appear again. But, of course, this is not handy at all!

there is something on the page that you visit that causes it to hide the mouse cursor. To reset move the mouse to the top of the screen and click the menu bar.

Since this happens about once a day, including during times when the computer is asleep, and since it never happened prior to the installation of Mountain Lion, this appears almost certainly to be a software error that Apple is either unaware of (due to their effort to shove problems into discussion groups rather than providing customer service) or that they have so far been unwilling or unable to solve (busy, no doubt, hyping another new product).

I've used Apple computers for 25 years and recommended its common stock for longer, but as hype and style replace quality and service, I'm beginning to have doubts about the company's future. Everytime I shut down and restart to get a cursor, I curse.

maybe it is as simple as repairing permisions in the disk utility. I would hold down the option key while starting the computer and boot up into the recoovery drive. Then I would reinstall Mountain Lion.

No, it's not that simple. All the usual tricks don't work (e.g. PRAM, fixing permissions, etc.) It's a bug. I have several computers running with Mountain Lion (new and old), all have the same problem EXCEPT one where I did a clean install and did not use Migration Assistant. All the others, where I used Migration Assistant, have that problem. Coincidence? I reinstalled all my apps. I'm thinking that there may be a conflict. Migration Assistant brings over all the old garbage system files.

Are you using a mouse or a trackpad?

I would be very interested to know if anyone here did not use Migration Assistant.

As I reported earlier on this board, I tried both wired and wireless mice and keyboards. As I survey my office, this occurs on three new Mac Mini servers which used Migration Assistant. It didn't happen on a MB Pro Retina, and older MB Pro, and a new MB Air where didn't use M.A.

It clearly happens to new and older Macs running Mountain Lion.

It's not a software issue from what I can see on this Board. It happens at different times for different users. In my case, it's upon awakening on all three mac minis regardless of the app used. Right now, the leading suspect is Migration Assistant unless some people report they're experiencing it without it.

Search for "mouse cursor disappears" in the Apple Discussions (the search automatically covers all topics, hardware and OSs) and you find that this problem has plagued Apple Computers since 2007! Let's face it folks, there is no overall solution. Its a variable bug and Apple are not taking it seriously. Let's just grit our teeth, keep going as best we can, and curse Apple if it makes us feel better.

I used Migration Assistant and got the disappearing cursor -- something I had never seen before -- on a Mac mini purchased a few months before Mountain Lion appeared.

I've owned and set up hundreds of macs since the the original classic; almost a dozen in this last year. Seems odd that I've never experienced a disappearing mouse until now. Not just once, but on three Macs in the last month. All using the same apps; all upgraded to mountain lion. And all with Migration Assistant. It's odd that the bug doesn't apply to all; so it's key to find commonality.

Have you allnused M.A?

Anyone experiencing this who didn't use Migration Assistant?

very rarely i experience it. When I do. I bring it to the top and click the menu bar. It is probably some preference that got messed up. I dont know. sorry.
