mouse and iMac froze up-- any ideas?

Post by georgeandjolie » Sat Dec 28, 2013 9:00 pm

Help!
IMac w/ Snow Leopard has froze up. Mouse is not operable either.
There were hints that all was not well prior to this such as screen going
black and mouse not working correctly-- but those were temporary.
All batteries tested ok.
Any one have ideas to offer?

By froze up do you mean the screen is black and nothing happens when you hit the power button?
Have you tried holding down the power button for about 10 seconds?
Time to make an appointment at an Apple store.

Thank you, Jay, for your reply. The screen was not black-at least not last night, it just froze up on the page I had been looking at. I could not get anything to change on the screen, either with the mouse or keyboard. Batteries in both devices checked out as charged. The mouse cursor was moving around, but only the "hand" was showing, not the arrow. There was no action when I tried to click on any part of the mouse's surface. The mouse and keyboard are both wireless. We have the Mac OSX Snow Leopard "missing manual" and attempted varying methods of "force quitting", none of which had any effect. Finally, I pushed the power button on the back of our iMac and turned the computer off last night. This morning, I turned it on, using the power button. At the moment, all seems to be working. As you can understand, visiting the apple store is a last resort. The troubling sign is that in the past few weeks, it has gone black for no apparent reason (2-3 times). Pressing the power button on the back resulted in recovery of the page last visited, prior to the blackout.

I'm trying to determine if you are having a computer problem or mouse problem. Is your keyboard wireless as well? Could be you are having a problem with Bluetooth connectivity, your mouse and keyboard lose contact with your computer which could make it appear that your computer has 'froze up'. Do you have a USB hub plugged into the computer?

Thanks Jay for trying to sleuth this problem.
To answer your question: no there is no usb hub installed.
Last night we did the unfavorable push the back button for shut down.
This AM all is good and so far continues w/o problems. However, it may
happen again. Please don't give up on us as we may be posting again about the
same problem and will ask for your (and anyone else's ) Dx skills.

Next time it appears to freeze try just lightly pressing the power-on button. See if it comes back.
Do you have a USB keyboard?

My iMac sometimes loses BlueTooth to the Magic Mouse. In some cases, the keyboard and Magic Trackpad work fine. Turning the mouse off and back on will sometimes bring it back, though sometimes you have to explicitly reconnect it in the BlueTooth menu. Unfortunately, that's only doable with another pointing device.
If all your input is wireless, it's a good idea to keep an old-fashioned wireless mouse around for just such emergencies.

On a couple of occasions, my iMac has lost all BlueTooth. Turning BlueTooth off and back on again can solve that problem. Again, you need some way to manipulate the iMac. (See below.)

I'd make sure that wasn't the issue before I'd worry about anything else that might be wrong with the iMac.

Force shutdowns of the iMac all the time with the power button is not a good idea.

It's not straightforward to set up a BlueTooth off/on switch for your keyboard. Here are some places to start:
http://www.axoniclabs.com/Bluetoggle/#
http://qsapp.com (reportedly can toggle BlueTooth, among many, many other things)
http://robcottingham.ca/2013/03/os-x-sw ... -keyboard/ (requires some AppleScript)

As I have occasionally needed this function, I'll keep looking.

Thanks for the tips Stephen.
We will try the USB mouse you gave me with the Power Book which I used to post the original "help" message.
Thank you again.
I very much appreciate the help always offered by the club members.

Thanks Jay.
I like the idea of by passing the bluetooth with corded keyboard; corded mouse. We have both.
You and Stephen have helped a great deal with this common theme.

Let us know if it looks like just a BlueTooth dropout. I've seen reports on the web of that happening to a Magic Mouse, so it's not just yours or mine. This has happened just once to my brand new Magic Mouse. (My older one suffered liquid-spill damage, but before that, it would drop out occasionally.) It's never happened to my wife's Mighty Mouse. As far as I've ever heard, this is a problem unique to the iMacs and the Magic Mouse.

When it happens to me, the BlueTooth menu item will show the mouse as still connected. If I switch the Magic Mouse off, it takes several minutes for the iMac to notice it's gone.
