BT mouse/keyboard won't wake my iMac

Occasionally, once or twice a month, the BT mouse and keyboard will not wake my iMac 27" 2.8 GHz i5 OS X 10.6.7. I must force close computer with the power button. I can hear the fan faintly kick in. Everything is fine when it turns back on.

The only solution is to use Apple supported Bluetooth hardware (which the Targus isn't).
Most third-party USB Bluetooth Adapters will work for some functions (such as simple file transfers), but unless it is Apple supported, specific Apple features such as Wake from Sleep and even iSync often do not work.
The ONLY Apple supported Bluetooth hardware is either the built-in BT hardware in Macs, or the D-Link DBT-120 USB Bluetooth Adapter.
It's always best to stick with what Apple recommends to ensure 100% compatibility and support.

Impossible, there are zero, as in none, zip, nadda viruses for OS X. If you have viruses on it they are for MS Windows and will not affect OS X. I suspect the hard disk has crashed, if you have backup then it's not a big deal to have it changed, just take it into your local Apple Store or AASP for service. If you have not been backing it up you may be in for a painful lesson on why backup is critical.

Apple keyboard or mouse won't wake up iMac from sleep.

After I put my iMac to sleep the keyboard or mouse won't wake it up. I have to push the power button to awaken it. Wake from sleep is enabled in bluetooth preferences so that is not the problem. Otherwise keyboard and mouse are working fine. Any help would be appreciated.

Regrettably, I can't offer a solution to the problem stated in the title. Instead, I experience the same problem.

Things worked fine until an upgrade from Tiger to Snow Leopard. Following the upgrade there were several mouse related issues. Those were resolved. One issue remains: waking by use of mouse or keyboard.
The setup (Same for keyboard and mouse)
System Preferences --- Bluetooth --- Keyboard Connected --- Keyboard Paired. The "Discoverable" box is checked.
Digging deeper
System Preferences --- Bluetooth --- Advanced --- "Allow Bluetooth device to wake this computer" --- This option is unchecked and is greyed out, inaccessible. Two of the other options are checked and available: the options about opening the Bluetooth assistant and the one about prompting incoming audio.
I've searched other posts. However, many of the other posts seem to conflate this Wake/Sleep issue with various connection issues. Thus, the advice given is a bit confusing to this amateur. Might one of you experts have a solution to this annoying little problem?

G3 Bronze Keyboard won't wake up from sleep

I have a hand-me-down Powerbook G3 Lombard 400 Mhz (bronze keyboard), with a dead main battery. It works great with the power adapter, and has just enough charge for me to move it from one outlet to another without shutting down. I'm trying to set it up for use as an Itunes server connected to my home stereo, which is fine because it will always be plugged in.
The problem is that the laptop won't wake up from sleep. This morning I noticed that the display and HD seemed to be sleeping, but the fan/processor buzzing noise was still going (there were no lights other than the little green light on my PCI card). I couldn't figure out any combination of keyboard or power key strokes that would either wake it up or shut it down. I unplugged it, waited half an hour or so, and it finally shut down. I then plugged in, hit power, and it started and booted perfectly (after the expected disk check for abnormal shutdown). Then this afternoon, the whole thing was sleeping (I think -- no sound, no lights other than PCI card light), and again it wouldn't wake up. Again, I unplugged, let it power down (waited for the PCI light do die), the replugged and it started up just fine.
Any idea what gives? Or what I do when it's sleeping? Right now, I have changed the power saving settings so that it never goes to sleep, but I'd really like to let it sleep when people forgot to turn it off...
thanks!

aldpol,
There are many causes for sleep issues and you just have to wade through them one at a time.
You can always force a Lombard or newer powerbook to shut down by pressing/holding the power button until it turns off. As you have noted, this is an undesirable process since you can corrupt the HD.
I would start the troubleshooting in this manner:
1. Unplug all peripherals (PC cards, mouse, everything).
2. Reset the power manager:
http://support.apple.com/kb/HT1431?viewlocale=en_US
3. Now put the powerbook to sleep via the Special menu, wait a minute or so, then wake.
4. If no success, restart while pressing the shift key until you see the message 'extensions off', then release. Now test sleep/wake.
If number #3 is successful, one of you peripherals is probably the troublemaker. If still having issues, please post back with more details if possible.

Aluminum Keyboard won't wake Mac mini from sleep (sometimes)

I just bought the new aluminum keyboard (wired). Its great, and looks amazing next to my mac mini......except it won't wake mac mini from sleep sometimes. When this occurs, I can tap on any key but the machine won't wake up. The only work around I have is to attach my ipod, which wakes the mini. Oddly this only happens sometimes. I can't isolate any other variable which may be influencing this behavior.
I'm running leopard and didn't think I needed to install the 1.2 keyboard software update.
I called Apple support, and they told me the problem is that I'm using a non-apple mouse (I have a microsoft optical wired mouse connected to the keyboard's USB port). I don't believe them as i've used this mouse connected to my previous Apple keyboard for years and never had a problem.
Can anyone help?

Won't wake up iMac

So since the Lion upgrade, my apple tv doesn't seem to wake my iMac anymore. I phsyically have to walk downstairs and wake the computer for it to work. This worked fine until the Lion upgrade. I haven't made any other changes with my airport extreme or apple tv. I checked my settings in the system preferences and the "wake for network access' is checked.
Any ideas?

I would ask this in the osx forum rather then the appletv forum
as I would say it's 100% a power setting on the imac issue

My keyboard won't connect to imac

I have a 2011 imac that has worked fine for several months but I recently installed some bad ram that caused my computer to do some crazy things. It stopped recognizing the wireless keyboard that came with it and has been used with it for 6 months. I have turned on the discoverable and the bluetooth, and the mouse still works fine. Sometimes it sees the keyboard and it just won't pair with it, and sometimes it won't see it at all. I don't know if there is a way to reset the keyboard or something. just kinda stuck on what to do with the situation. Any ideas?
I was running 10.7.5 when the issue started, but have updated to 10.8.2 now in hopes that that might help but it hasn't changed anything.

Select  ▹ System Preferences ▹ Bluetooth. Select the device in the list on the left, then from the action menu (gear icon) below the list, select Update Services. If there's no improvement, delete the pairing from the list and recreate it.

Apple Blue Tooth Mouse & Keyboard will not Wake Mac Pro while in Vista

I am running Vista Ultimate via Boot Camp OSX Leopard. I have a MAC Pro with apple blue tooth mouse and keyboard.
When the computer sleeps while in Vista, neither the mouse or keyboard will wake the computer. The only way to wake the computer while in Vista is to press the power button the MAC Pro.
After I wake the computer via the power button, the keyboard is unresponsive for about 2 minutes. Turning the power on and off on the keyboard does not speed up the process. The same thing happens intermittently when rebooting into Vista.
AppleCare says it's a Vista problem. Microsoft tech support says it's an Apple driver problem. Nice.
The keyboard and mouse do wake the computer when in Leopard.

Were you ever able to find a resolution to this issue? I am seeing the same perplexing grayed out box in device manager. In my case I'm using a MS Bluetooth keyboard and mouse and my machine is a Mini.
For anyone else who might happen upon this post, the exact click sequence is:

Apple Wireless Keyboard won't pair with iMac...

I just bought a new 27" iMac and had customized and shipped from Apple (didn't buy it off the shelf in the Apple Store).
When the new iMac got here today, I connected it to my aftermarket (wired USB) keyboard and trackball. It works fine.
My problem is that I need to use my old iMac for several days while I get files off of it, etc. (don't want to use migration assistant). My old iMac is last year's 24" model.
When I start my old iMac, it comes on and brings up a "Bluetooth Setup Assistant" window and starts automatically searching for a bluetooth keyboard. I read the instructions online, and powered-on the Apple Wireless Keyboard that came with my new iMac. I powered on this new keyboard, and my old iMac starts to recognize it (it says "Attempting to connect to keyboard"), but then says there has been an error, and doesn't recognize it.
The instructions online say that when I power on my Apple Wireless Keyboard, the green light on it should start blinking. It doesn't. It just comes on for about three seconds and goes off.
What's wrong? I need to get my old iMac to recognize this keyboard. I can't even safely shut if off if it doesn't. Could it be that it was already paired to the iMac it came with? I've replaced the batteries, and still it doesn't work. Please help!
Thanks!

Well, of course that had occurred to me. But I need to use both computers at once for a while, and I only have one wired, USB keyboard.
Anyway, I eventually got it to work. I still don't know what the problem was.

Won't wake up from sleep, sometimes get blue screen and can't get it to wor

I have two problems that may be related. I am using a PowerBook G4 (Tiger 10.4.5). Sometimes when I turn it on I get a blue screen and that's it. Nothing else will come up. I have to do a forced shut down and then restart it with the shift key depressed and run repair disk permissions and then it works okay till the next time it decides to return to the blue screen (once a day approx.).
Also, sometimes it goes to sleep and will not wake up. I have to shut it down and then restart it (sometimes getting the dreaded blue screen).
This just started happening after I installed Tiger.

Hi, vfv. Welcome to the Discussions.
1. You wrote: "Sometimes when I turn it on I get a blue screen and that's it. Nothing else will come up. I have to do a forced shut down and then restart it with the shift key depressed and run repair disk permissions and then it works okay till the next time it decides to return to the blue screen (once a day approx.)."Your description suggests a corrupted or incompatible Startup or Login item. As Adrian suggests, my "Troubleshooting Startup and Login Items" FAQ can help you determine which Startup or Login item is causing the problem.
2. As to the sleep problem, here are some ideas for you:2.1. If you are using a Bluetooth keyboard or mouse, see "Mac OS X 10.4 Help: My wireless mouse and keyboard won't wake my computer.".
2.2. Your Mac maybe frozen or hung. Troubleshooting freezes and hangs is not unlike troubleshooting kernel panics: the steps are virtually the same. For a more exhaustive troubleshooting procedure, you could use the steps in my "Resolving Kernel Panics" FAQ.Good luck!

Hi 02SilverSport,
Try using the power button to wake the iMac.

If you are using a wireless keyboard or mouse, check out this article:

Imac won't wake up since 10.4.7 update

Hello! I have a 17" imac g5 (purchased in 12/05) that will NOT wake up from sleep now since I have done the OS X 10.4.7 update. I have to hold the on/off button for at least 5 seconds and by the 2nd or 3rd time it will finally come on. Any ideas?? The only peripheal I have is a card reader. It does it with that unplugged. I also fixed disk permissions, still won't wake up. Since I am still relatively new to Mac, I need detailed instructions. Thank you so much in advance!!

Hello,
At this point, it would seem that you are down to two last options:
1) Re-install OS X from your original Restore disks.
2) take it in for repair and see if it's a hardware problem.
I think you have the last version of the iMac G5 (the one with the iSight). If so, you are still under warranty since those came out around November or December. So, you should still be in your first year (a 3 or 4 months left).
I think at this point, it would be best to do two things:
1) Run the hardware test that came with your computer. See if that finds a problem.
If it does, we'll stop there, and let you take it in for servicing.
This should be on one of your restore disks. It will say Apple Hardware Test on the disk somewhere (smaller print). And, provide directions for starting the test on your particular system.
Now, once you are in the test, run both the standard and extended tests. See if either finds a problem. This could take a couple of hours.
Let me know what it says.
2) Now, if it doesn't find any problems, then I would propose that you re-install OS X from scratch.
I would first copy any important information to an external drive or disk.
If you have an external hard drive, you could make a full backup of your entire hard drive using a program such as Carbon Copy Cloner:
http://www.bombich.com/software/ccc.html
This program can be used to create an exact clone of your main hard drive.
So, it is a bootable backup that can be used to put your entire system back exactly as it was at the time of the backup.
This means that if something happens, you can boot from your external drive, and resume normal work. Or, you can boot from the external drive and run the program again to restore your computer to match the backup.
This backup is an exact clone of your entire installation, so it is readable by another machine.
It works great, and I've never had a problem with it.
But, I use the "Clone" feature.
This has the advantage of being able to restore quickly, and return back to the exact point you were at when you backed-up.
In your situation, we would use this backup for two purposes. First, it ensures that all your important information is backed-up. Second, it means that if your new installation doesn't fix the problem, you could just revert back to this installation and everything would be like it was.
Now, if you don't have an external drive, then just backup your important files (e-mails, documents, downloads, anything of importance to you) to another disk (CD-R or DVD-R, etc.).
Make sure you get the 10.4.7 Combo Update stored somewhere so you can update again without downloading it.
Once you have verified that everything you want is safely stored on another disk or drive, then you could proceed with the re-install.
Make sure you disconnect any external drives (FireWire, USB) and other accessories before re-installing. Just keep your keyboard and mouse connected.
You can install OS X by booting from your Restore disks. Insert the disk, and restart while holding down the letter C on your keyboard until it finishes booting from the restore disk.
Once started-up, I would personally recommend using the "Erase and Install" option. This will give you a completely fresh installation without any of your old bugs getting carried-over.
The "Archive and Install" will basically install a fresh copy of your OS X while preserving your settings and installed software.
Here's a good article summarizing your options and how each works:
http://docs.info.apple.com/article.html?artnum=301270
The problem with Archive and Install is that sometimes problematic settings will survive using this method.
So, for best results, use the Erase and Install. Since you already have everything copied to another disk, this shouldn't be a problem.
Once the fresh installation is done, then see how your system behaves.
If everything is fine, then immediately install the 10.4.7 Combo Update.
Now, repair permissions.
See how things are now.
If everything is fine, then go ahead and setup your e-mail, programs etc.
Copy your data and files back, and resume operations
3) Now, if things still don't work right, then call your service shop and arrange for warranty repair.
It is a pain to go through all these steps. But, the service shop will blame software first unless the hardware test reveals a problem.
So, by doing a fresh install, you beat them to it. You can tell them you have already done that, and know the problem is hardware related.
Anyway, I hope that the re-install isn't needed. But, if it is, then the steps are listed above.
Start with the hardware test and other ideas above first. But, if those don't work or reveal something, then go ahead and re-install and let me know what you find.
Keep me posted on your progress, and let me know what does or doesn't work for you.
I hope this helps.

Can't use mouse/keyboard/trackpad when waking iMac from sleep mode

Basically as the title says. When I wake my iMac from sleep mode I am unable to use my keyboard/trackpad/mouse during the login window. Once the screen goes black by itself, after a minute or so I can then log in properly.
Yes the keyboard/mouse/trackpad are all connected when it wakes from sleep as I can use any of them to wake it from sleep, I just can't move them or type with them in the login window.
Processor 3.4 GHz Intel Core i7
Memory 24 GB 1600 MHz DDR3
Graphics NVIDIA GeForce GTX 680MX 2048 MB
Software OS X 10.8.5 (12F37)

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

IMac won't wake from sleep

New iMac 27 purchased Feb 2014. If the computer is allowed to go to sleep, it won't wake up. Neither taping the keyboard or mouse has any effect. Pressing the power button whether momentarily or holding it for up to 30 seconds brings it back. The power cord must be unplugged for at least 15 seconds, plugged back in and the power button pressed to bring it back.
Setting the computer to never sleep seems to be the only thing that resolves the problem.
Allowing the display to sleep is OK.
Manually choosing sleep from the Apple logo is OK.
