Mouse cursor disappears.

Same problem here. Never saw it until Mountain Lion. I clean installed Mountain Lion and rebuilt my system from scratch. Photoshop CS5, Wacom Intuos 4. Mouse cursor disappears while working in Photoshop. Workaround is to Command+Tab thru several apps and return to Photoshop. I have reported this on Adobe's Photoshop user forum, where it is considered an Apple bug introduced by Mountain Lion.

I have the same problem but I am running Mac 10.6.8 Snow Leopard on MacBook Air. The screen goes black. Eventually, I can press on the return key and get back in. But, when the screen returns to normal, the cursor has gone However, I am able to enlarge the items in the tool bar by running the invisible cursor over them. Eventually, the cursor returns. I am on my eighth crash tonight. Not a good day.

I notice this also when there are multiple bluetooth devices in the vacinity... especially bluetooth trackpads or mice. I shut bluetooth off and there is no more interfereince from other bluetooth devices.

Wow, is Apple UNRESPONSIVE or what?!? I have a comparable issue with my cursor behaving at the left and top portions of my screens but not the bottom and right portions where it goes off and thus disappears until brought back.

Thanks, Carlo. I believe that a reasonable expection of users of "Apple Support Communities" is that the most successful corporation in the U.S.A. monitors support threads if only in China where it has outsourced so much of its operations. Anyway, I did try your suggestion (but did not reboot) and the cursor continutes to exit the same two margins. Perhaps there is some setting which indicates monitor dimensions different than as they appear.

No, it's chronic not intermittent. But, it happens when I take the cursor to the bottom or right sides of the screen. My Apple daughter looked at it and thinks that it might be to "hide the cursor" but should be changeable.

I found my cursor disappearing when using Safari, but not with Chrome or Camino. I read on a Mozilla page about the same problem happening with Firefox. There the solution was offered to empty the cache and remove all cookies. I did this for Safari and the problem was gone. Use 'set back Safari' or similar under 'Safari'. It's 'Safari zuruecksetzen' in German. There is probably a cookie disturbing the cursor action. May be somebody tries to track our cursor movements.......

For me the cursor is disappearing frequently when I am using Word and Filemaker and sometimes Firefox. As I indicated above, 3 finger swiping to another screen and back recovers the cursor.

I suspect that this is happening where the cursor size (Sys Prefs/Accessibility/Display) is set to larger than "normal" in a previous version of the OS (in my case Snow Leopard). Maybe there is a way to trash the prefs for this selection and start afresh?

Well, my newest idea is that the cursor disappears when you have to monitors connected, which are not sinced, different things displayed. Then, using on one of them Safari (or its webkit) in full screen mode. Then the cursor disappears on the other monitor. If you dont use Safari in full screen mode, but Chrome or Camino, the cursor stays, no problem. Even if you use Safari on the other monitor (as long as it is not in full screen mode). Emptying the cache or resetting the preferences does not really help. I withdraw my previous post........

I only have the disappearing cursor in Photoshop CS6.

(I do not use multiple screens, other than normal cursor size setting etc.)

I did a clean Install of Mountain Lion.

No Migration Assistant used at all.

The cursor will disappear quite often.

As far as I realized it is always when cursor moved above canvas at the very moment when it enters the palette windows. (When it would change the appearance letz say from brush to the arrow)

I then go to the dock - it is enough to let the dock pop up - and back to Photoshop everything is fine for a certain time. That may happen every few minutes.

A friend has the same issue under 10.7 Lion since he moved to Photoshop CS6...

Islandphotographer: Like you, I have Mountain Lion, I use CS6 Photoshop everyday, did a clean install without migration assistant -- but I don't have the dissappearing mouse anymore. Since this is not a universal problem for all Mac users, I suspect there's a third-party system app file conflict somewhere or corrupt plist file.

My solution came about the same time I was dealing with another bug. Perhaps fixing one problem solved my dissappearing mouse issue. The problem was that my computer kept going to sleep and the solution turned out to be a conflict with Transmit (an ftp download app) menu bar feature. I deleted the application support feature (finder pull menu GO with Option key held down to access library application suppport; then trashed Transmit menu bar app and rebooted) while some people in this forum said they just turned it off.

Just a thought: Maybe re-do a clean install and introduce 3rd-party apps until you see the problem again.

A quick question, is anyone using the following apps/tweaks?

- Mousefixer (script)

- Menumeters

- cyborg Rat (driver)

- Wacom Tablet (driver)

Since we are looking for a 3rd-party app, maybe we all have one in common.

I didn't use any of those. I had various utility apps and MS Office. None of which were reinstalled. Once they were gone after an install; so was my mouse problem. Maybe try disengaging login items and apps that automatically launch. Boot by holding down shift key. See if the problem occurs without your start up items.

I had Office 2008 and then Office 2011 installed on my iMac. I don't recall when the cursor problem started but I think it was after that and after I sync'd up my iMac and a surviving Dell monitor. I was able to change which two sides of the screen that my cursor escapes past but it seems to randomly jump/disappear without me taking it out of bounds.

It's simpler than this. Use the color picker tool in the colors menu in any iWork application (e.g. Pages '09).

Works every time for me.

The cursor disappears and the best way to get it back is CMD+Tab to another application, then back and the cursor reappears.

I have another Mac running the same version of iWork but an earlier OS (10.5.8) and no problem - ever.

Come on Apple, this cannot be rocket science.

Also, am I the only one experiencing sever slowdown problems with OSX 10.7.5? I have a MBP 15-inch Early 2008 model.
