New to Mac computers. When trying to open computer after being in sleep mode, I clicked the mouse to open the password screen, & a blank blue/black screen appeared & the mouse timer( colored circle) appeared, as if to be waiting. I had to unplug the computer to reboot it. This has happened twice in 2 days.
I have an early 2008, 24-inch iMac. This problem started after I installed an OS X Mavericks update (and has continued). Basically, after the screen is asleep for a while, if you come back and move the mouse / tap the keyboard, the desktop never reappears. The screen stays black but the mouse cursor shows up and you can drag it around. I've seen some similar issues that said they could get the app switcher, but that never happens for me. Just mouse cursor and black screen, no matter how long you try to wait it out or tap buttons. The only solution is a cold restart, although I think in the past I was able to fix by turning off energy saver settings for putting the display to sleep. It doesn't happen every time, I'd say it happens over 50% of the time. The problem actually kicked in with one particular App Store update of Mavericks. I believe it was 10.9.3 if I recall correctly.
my mouse arrow cursor changes at will - it becomes an ibeam or a hand (like the one used when pointing to a link) and then will switch back to an arrow. I use a Logitech wireless mouse with plugged in USB receiver. I turn the mouse off whenever I stop work. I changed the batteries on the Logitech mouse yesterday and it had no effect. I tried using the Magic Mouse (which I love, but which has problems of its own - it eats batteries for breakfast and it's not consistently recognized when I wake up the iMac and I have to resort to the Logitech mouse to get going so I rarely use it) to see if it did the same thing and it does. I am still running 10.6.6 and haven't added any software or done anything strange. I did update Firefox to 9.0.1 a while back, but things were fine a long time after I did that.
I just bought the latest macbook pro. It is actually my first mac so I'm not really sure if this is supposed to happen. But I tried plugging in my "ordinary pc" (meant to say that is not a Mac mouse) mouse which is an A4Tech brand. It's working when I move the mouse in huge spaces. It goes smoothly that way. But when I try to move it in small little spaces, it's kind of like not going smoothly. Especially when I'm working on small details like Photoshop, it's kind of difficult to maneuver the mouse arrow. I tried other "pc" mouse as well but it's just the same.. Does this really happen if I'm not using Mac's mouse? How do I fix this?
Middle of last month I bought a 20" IMac. Everything was fine up until about 1 week ago when the screen went black. I clicked on the mouse button several times only to have a password box pop-up. After filling in the response, all was fine.
Next, same scenario but the password box didn't appear any more. The only way to get the screen back was by a forced restart.
I turned off the screen saver, set the 2 controls in energy server to off, unchecked the box at the bottom left & put "auto login" to to on the Accounts window.
Next move was to zap the pram, this was 2 days ago. The screen didn't go black but often asked for my pw. It's now back to its beginning phase which is a forced restart !!
I was told that it was due to Leopard 10.5.2 & am considering going back to 10.5.1
My beloved imac desktop just started this after a brief power outage (it didn't affect my husband's imac) or any other machines in the household. I've tried booting while holding the 'option' key but it still goes to "no bootable device" ...

I have a 27 inch desktop. Upon turning the computer on within seconds the fan comes on. Then it goes to a high fan. Then it goes to a black screen. Then it shuts off. Then if you click the mouse it will come back on. This cycle repeats itself every 5 seconds. Only one time in the past month did it turn on normally and run for me.
My screen had black and white vertical lines pop up over the entire screen then went blank and now at a restart the password then loading spinning circle happens then I get a blank white screen.It's a 27 in Intel iMac that is about 2011/12 purchase
"Jack" when on "Jill's" computer without her knowing and altered her desktop "organizing" system. Now, some of the icons/files show the Preview paper icon with the arrow (from the attached image) and won't open at all.
I've had my mac for about three years now and everything was working fine. After I installed lion, I notice that this started to happen. I don't lose any of my information though when it does that. It just goes into a sleep mode I guess? Anyways, is this a feature from the lion update? Something standard?
Upon start up my screen goes to normal gray w/apple logo and spinner then goes black. Cursor is visible and still is moveable but nothing else. I safe booted and bar came up also but then back to black screen.
I have a Imac 27", bought ut two weeks ago. Some days ago the double tap on mouse made the screen to be zoomed in. Now it doesnt work anymore. When i go to settings- mouse , then its saying there that the double tap to zoom its activated- BUT IT DOESNT WORK ANYWAY??

I came back from work to wake up my iMac. It made the noise but the screen stayed black. I tried restarting by holding the power button- I can hear it start and the chime but still have a black screen. I tried resetting the pram, and unplugging the cord but I still get a black screen. I can hear the chime though; I'm not sure if that means anything. I just had the hard drive replaced in February so I hope it's not that. just wanted to clarify that when I restart, I get the chime but the screen stays black- I don't get to the grey screen. So I'm assuming right now that my display may be shot?
I recently purchased a refurbished 24 inch imac from the noticed when the computer is idle (black screen), my wired mouse does not work. When I pull the cable out of the usb port on the imac, the computer screen comes on and then I reinsert the cable back into the usb port in the computer to use the wired mouse (wired mouse works fine after I reinsert the cable back into the usb port).Could this problem be associated with the wired mouse or with the usb ports on the imac?
You move the mouse over to the scroll bar, favorites bar, minimize, etc... and the mouse is stuck in the wrong icon, be it the text pointer, hand pointer, window resize pointer... when it should be the arrow. It is such an obvious bug and I can't believe Apple hasn't noticed this.
