Help. iMac won't start with Bluetooth keyboard

Hi, iMac has decided to quit on me. It kept going to the grey screen of death at startup and triedd resetting everything. Nothing worked until I unplugged everything and noticed when I shut the Bluetooth keyboard off, only did it start up but much slower than normal. Any ideas or suggestions on whats going on? Basically, everytime I restart my computer, I need to make sure the keyboard is shut off and it still loads very very slow. Thank you.

Hi, Warren
try to reset PRAM.
try to repair disk permissions.
slow loading/running is sometimes connected with too little memory? how much do you have, and is it sufficient? (have a look at the Activity Monitor).
please, post back with more details.

IMac won't start with Thunderbolt Display connected after firmware update

After updating my thunderbolt display firmware to version 1.2 this morning via the App Store, my mid-2014 iMac won't start up with the external display connected. I can get the iMac to start up only by disconnecting the display's thunderbolt connector. After the iMac comes up, I can reconnect the display and everything appears to function normally. I've tried several restarts and the iMac won't start up with the display connected. Anyone else experience this?

IMac won't respond to Bluetooth keyboard

Our late 2009 iMac is not recognizing a known good Bluetooth keyboard. I would like to get into the iMac's library but can't because I don't have an alternative (such as a wired keyboard). The iMac does recognize the wireless mouse. Is there any way to access the library without a working keyboard?

What happens when you tried using a wired keyboard & mouse?
How long is "in a while?"
When posting in Apple Communties/Forums/Message Boards.......It would help us to know which Mac model you have, which OS & version you're using, how much RAM, etc. You can have this info displayed on the bottom of every post by completing your system profile and filling in the information asked for.

IMac Won't Boot With USB Keyboard Connected

We have a suite of 10 iMacs (10,1 - 21.5 inch), but one of them will not boot and has issues coming out of sleep while a USB keyboard is plugged in.
Have tried swapping the keyboard with another iMac - the other iMac still boots but the problem iMac continues to play up.
Tried plugging the mouse into the iMac's USB instead of the keyboard's.
Tried SMC reset, PRAM reset.
Re - imaged the machine from a time machine backup of one of the other iMacs, which made the issue go away for about a month... but then it returned.
Using a magic keyboard is fine as a workaround, but the users need the number pad, and if possible I'd rather fix the issue than buy a clunky separate keypad.
Does anyone have any ideas? Any help would be very appreciated!

Hello strathglass
The same thing can also happen with other connected devices such as external HD's and iPods, the Startup Manager is lost and searching for a boot volume.
1. You may be able to fix it by going to: *System Preference / Startup Disk* and select the *Mac OS X 10.5.5 on Macintosh HD* then *Click the lock to prevent further changes.*
2. Leave those devices that cause boot issues disconnected until the iMac is up and running!
3. Only sleep the iMac, and be sure to disconnect those devices be for shutting down or updates that require a restart!
As a habit, I have always ejected and disconnected all mounted USB devices (flash driver, iPods, cameras, card reader, etc.) from my hub be for sleeping, restarting or shutting down...

Please help--iMac won't start up

My daughter has an iMac G4 flat panel (OS X 10.4.8), and a serious problem. I've been trying to help her but have run out of ideas. She recently downloaded and installed some updates. After installation, she clicked the restart button, but only got a blue screen with the beach ball appearing (apparently not steadily, but kind of intermittently). She turned it off and tried to restart several times and got the same thing. Then, she tried to start up from the disk. I'm not too clear what happened at this point. But she did manage to repair permissions. But this didn't help. Then, she tried to repair disk, but the computer told her she couldn't do that (I'm not sure why). Finally, she reinstalled OS X. Upon doing that, all she gets is a blue screed with a box containing her name and two buttons--quit and restart. She has tried to restart many times, but just comes back to the box with the the two buttons. I have been trying to help her over the phone (she's in MD and I'm in WI). So, having not witnessed any of this first-hand, I can't be much clearer about the situation. Obviously, one possibility is going to the Apple Store. But she really can't afford that. Does anyone have a suggestion?
Thank you,
Carl Kalwaitis

Hi Supreme D,
first check your internal battery.
With your computer you have to keep a certain order of installations.
1. Backup!
2. Boot up from the 9.2.2 install CD and reformat the hard disk (this is important because you need a bootable OS 9 for the firmware upgrade)
3. Install OS 9.
4. Make sure you can boot into OS 9!
5. Upgrade your firmware: Mac OS X: Chart of Available Firmware Updates
6. Insert the 10.4 install DVD and reboot while holding down the c-key
7. Once the installer has started and you selected your language select "Disk Utility" from the MENU
8. Repair the disk and select "repair OS 9 privilegies" from the MENU
9. Quit disk utility and proceed with the installation of MacOS X
10. After the restart Repair permissions!
11. Download and apply the standalone Mac OS X 10.4.8 Combo Update (PPC)
12. Repair permissions again.
13. Run software update from the Apple menu and apply all available updates.
Good luck!

Help. iMac won't start up anymore...

And it's making a weird 3 beep sound. I've checked Apple's web site and according to them it's a memory problem, but I haven't added any since I bought this computer 3 years ago. I tried resetting my PRAM and PMU and still get a 3 beep and no start up.
I'm running Panther, but not sure which version and can't find my start up disk...
Any suggestions??
Thanks.

Thanks guys. I broke down and took it into the shop...it's way past my expertise and since we've moved we have no idea where the disks are.
Hopefully it won't be too expensive...

IMAC won't start with external USB drive

I've been running Leopard for a few weeks now and decided to connect an external USB hard drive to use with Time Machine, it did the backup fine and seems to be working fine... however, every time I start my imac in the morning I get a gray screen that just hangs. I have to unplug the USB drive then reboot again.. that salves the problem.. but is annoying to have to do that each time.. I also noticed today that my ipod when plugger in via USB will not mount on the desktop.. I have to unplug the USB hard drive then plug the ipod in again.. that solves the problem..
Anyone have this same issue..??? It seems to be USB related or Time Machine related.. maybe both..
Cheers
D.

The Disks are formatted with Ntfs as i am using Bootcamp with Windows 7. So repairing disks would not work in Mac OSX, and is not needed as the disks are ok. I would be a strange coincidence that both disks would be corrupted at the same Time.
I have tried three different other USB disks in the meantime and the Macbook could Boot up everytime with no problem. I found the answer in another forum. The controllers (USB to SATA) in the enclosures of the disks are not compatible with my Macbook, they are rather cheap WD disks and a lot of other users reported the same problem. ist might be possible to upgrade the firmware, but i will rather look for some other disks and try them first before i buy.

Intel iMac won't start - HELP!

My iMac won't start this morning. I get the white screen with the grey apple,
and the swirling progress thing, then after a few seconds I can hear
the sound you hear when the system shuts down. like a soft switch
going off, then it just continues swirling, still with the white
screen and grey apple, then it restarts by itself. Then we go through
the same routine. Tried booting up by holding C with the Leopard disc inside but nothing happens.I have just reinstalled Leopard as Snow Leopard left too many printers and programs lifeless, so I did an erase and install a few days ago. Since then I have used the Mac fine, switched down normally last night, but this morning it doesn't want to play.
Any thoughts?
Thanks in anticipation
Chris

Have you reset PRAM and SMC?
Do this first
http://support.apple.com/kb/HT1379
and then do this, if the PRAM does not help
http://support.apple.com/kb/HT1543
The second one is basically disconnecting your iMac from power (and all cables), then reconnecting following a precise procedure.
If that does not help, I would restart with the Snow Leopard installation disc (insert disc and start up with the C key held down). You probably did an installation of Snow Leopard over your existing Leopard system the first time. This time, erase it completely first, then install Snow Leopard. I assume you backed up your data already.
When you get to the Installer screen (after selecting language), go up to the menu bar. Under Utilities, select to run Disk Utility. In the sidebar, select the internal DRIVE, not the volume indented under the drive. Go to the Erase tab. Name the volume +Macintosh HD+ and set the format to +Mac OS Extended (Journaled)+. Erase the drive. Since you have the drive selected in the sidebar (not the volume), it will also re-partition the drive.
It should take less than on minute to complete the process. Quit Disk Utility to go back to Installer. Run the standard installation onto the blank internal drive. Hopefully, a fresh Snow Leopard install on a reformatted/re-partitioned drive will work better for you.

G5 iMac won't start! Help needed.

Got a new intel iMac. Gave my husband my old G5 iMac (not intel). It was working perfectly. For some reason unknown to me, he decided he was going to reinstall everything from scratch so he grabbed the first disk he saw and put it in the computer. It was the startup disk for an intel computer & NOT for the iMac G5.
Did he fry the computer? It won't start up. Keypad & mouse won't respond.
The screen can't find the driver (no surprise) and says "panic: we are hanging here...." I can't get the disk out of the drive. Service contract is up. Is there a way I can connect my laptop to it and get it to respond & spit out that intel disk? Perhaps if I open the cover up, I can into the CD drive and get the disk out. All ideas appreciated.

Hi Mel Kev
Have you tried holding down the left mouse button when you turn the computer on. Holding down the left mouse button should force eject the disk.
Hope this helps

And it WORKED! (I really wasn't in the mood to do surgery on the computer this evening). Thanks all!!! You are awesome!

Hi Paula2808,
I’m sorry you are having trouble starting up your iMac, that must be quite frustrating. There are some troubleshooting steps I would suggest in order to get you up and running again.
First I suggest using the steps in this article for the Apple logo appearing -

http://support.apple.com/kb/TS2570
If things still are not working correctly, you may want to continue with the steps in this article -

Thanks for using Apple Support Communities.
Best,

My iMac won't start normally it will start on safe boot unless I start in verbus mode single user mode or reset the pram but if I start this way it won't sleep

help mi imac won't start normally

Hello!
Can you tell us what happens?
I’ve offered the steps below to similar posts in the past and they helped out getting to the solution (or at least find the cause). I suggest them to you too in this case. It will take you about 30 minutes or less to do these, depending on how bad the problem on your Mac is.
The goal here is to boot your Mac to the so-called Recovery partition where you’ll have a chance to repair the disk and the disk permissions using the Disk Utility and Password Utility. This might solve your issue and even if it doesn’t- it’s still a decent maintenance step to perform. These steps won’t erase your data or reinstall your Mac in any way if you follow instructions carefully.
Here’s how:
1/ Make sure your computer is completely shut down.
2/ You’ll have to be quick next: Press the Mac’s power button. As soon as you either hear the loud chime, or see the display light up - usually after a second or 2 - on your keyboard press [cmd] + [r] Keep these keys on your keyboard pressed until you either see an Apple Logo with a loading bar or a spinning gear.
After a few minutes, you’ll be presented with a Utilities screen. This is the Recovery partition. If this step is already giving you problems, try using a USB-keyboard. It doesn’t have to be an Apple-keyboard. If you have a Windows-tailored keyboard laying around, use the “Windows-flag” key in stead of the [cmd]-key and it should also work.
3/ Choose Disk Utility and click [continue]
Disk Utility will display your computer’s harddrive in the left column. The default name for it is “Macintosh HD” and is usually the second one from the top. Click on it and click on the [verify disk] button. This will check your “Macintosh HD” harddrive partition for errors. If found, click [repair disk] unless you have a Fusion drive in your Mac and it says [fix] instead of [repair disk] please tell us before you continue! For a screenshot of what I mean, check this article from Apple: http://support.apple.com/en-us/HT202574
4/ Once done with the verifying or repairing of your “Macintosh HD” click [repair disk permissions]
This will check your partition for permissions errors. A common myth about this feature is that it will fix all permissions issues on your Mac, which is not true, but it will fix most systemwide issues. Also, here is a list of error messages that you can safely ignore if they pop up:
http://support.apple.com/en-us/HT203172
5/ Lastly we shall do a permissions/Access Control List repair on specifically your user’s home folder with a somewhat hidden tool in the Recovery partition. Close Disk Utility and find the menu called “utilities” in the top left corner of your computer’s display. It’s in between the menus “edit” and “window” Don’t be confused with the menu called “os x utilities”
Choose Terminal. A somewhat old-fashioned looking window will pop up, waiting for a text command from you. This is the Terminal.
After the # type: resetpassword and press return. Note that there is no space between ‘reset’ and ‘password’
What you’ll see next is an rectangular window that gives you the option to reset passwords. We are not going to that, however. Instead, click on “Macintosh HD” at the top. In the pull-down menu below that, choose your user's accountname. Skip all the rest and at the very bottom click the [reset]-button.
A spinning gear will appear and may stay on for a second or several minutes. It’s hard to predict exactly how long.
If you have multiple users on your Mac, I advise you to repeat this step for all your users.
We’re ready to reboot your Mac now. Click on the Apple Menu and choose “startup disk” Choose to boot from “Macintosh HD” Please let us know if this solved your issue, or if the steps above did not work, or could not be performed for some reason.

IMac won't start - should I reinstall OS?

Recently my iMac won't start up - it goes to screen with folder + question mark. I've run Disk Utility, repaired hard drive, but there were no reported repairs to make.
Occassionally it will start up, and everything seems normal until suddenly the beach ball appears and everything freezes. 99% of tries it won't start up (i get the ? folder). Is it worth erasing the disk and reinstalling everything to see if a fresh start will help, or is it likely that the hardware is damaged?
Don't want to bother erasing it if there's no point... any advice greatly appreciated.
Also - anyone who's had their iMac repaired - what are the costs like?

I've just suddenly had the same problem - for no apparent reason as far as I can tell. The night before last I switched off my iMac as normal, and yesterday morning switched it back on. At first it would start, but crashed as soon as I tried to start any applications. Then it wouldn't start at all, and just got as far as the gray screen with the apple on it. After trying resetting the PRAM, switching on and holding the on button for 10 seconds, it was no different...
So, I tried doing a archive-reinstall from the original leopard DVD I bought from apple. This did a successful disk verification, but then said it couldn't install mac os due to a problem with the basesystem package. After that it wouldn't let me try another archive-install and only gave the options to install as new, or erase and install. The latter I don't want to do, and the former just gives the same basesystem error... All I get now is a flashing folder with a question mark and not even the gray screen...
I have tried using the diskutility to verify/ repair the hard drive and it says all is well...
I have heard this may all be due to dodgy RAM chips, but I have never messed with them or altered them. It just seems odd they should suddenly fail when they were working fine before.....
Any ideas would be much appreciated. A lot of data at risk
Dan.

IMac won't start without install disc

Hi, I'm new to all of this. I tried resetting my admin password using install disc on my iMac as I'd forgotten it. Now iMac won't start without disc. If disc is ejected on restart apple logo flashes between no entry sign and folder with "?" on it. Will start up with install disc in, but then wants me to choose language and install OS. Tried repairing and verifying HD and all seems ok. Tried holding option key and selecting HD on startup, but same outcome - choose language and install OS. How do I get back to normal desk top? Do I have to install OS again? Will I lose data? Please, please help! Thanks.

It should only take a minute or so at most to boot from the DVD.
If your sure you have the correct Install Disk for that iMac, I'd start over. Then if it still doesn't work then perhaps a trip to your Local Apple Service Provider with the Disk or Disk and iMac is in order.
http://www.apple.com/buy/locator/service/
Alternately using the correct Disk as per the following article, see if you can run the Apple Hardware Test? > http://support.apple.com/kb/HT1509
