Unresponsive iMac 27" i3 had to be unplugged it before I could reboot. What's up?

My iMac 27" i3 wouldn't wake from sleep this morning and wouldn't boot with the power button until I unplugged it and replugged it. What gives? This has never happened before. Should I be worried?

i didn't read a lot of your 2nd paragraph, but it seems like the password is the issue, right?
do a true clean install
reboot your machine and hold down command+option+r, you should see a spinning globe - if you don't see the globe or anything that reads internet recovery, shut down and try again
at menu, chose disk utility and once there, find your HD on the left side, select the physical name and erase it as mac journaled
exit disk utlity
at menu, choose install OSX
this time, when it asks for a password just hit continue, it will let you complete without a password
you should be able to get into your laptop, now figure out what password you'll be able to use with your kb issue

IMac no longer recognizes MyBook after unplugging it without ejecting first

I recently got an iMac and had backed up my information to a MyBook external hard drive. It recognized it with no problem until I accidentally unplugged it before ejecting it. Now the MyBook doesn't show up at all, anywhere. How can I get my computer to re-recognize the MyBook?

Hi. Thank you for your response. I actually didn't get to test it out because before going to bed, I shut everything down, unplugged it, and said a prayer. (All of which I had done earlier in various combinations, except the prayer part.) This morning I plugged the computer in, turned it on, held my breath, and plugged the MyBook in - it recognized it and I downloaded everything onto my iMac before it could change its mind.
I'll keep a copy of your reply so that I know what to do the next time I pull a stunt like this.
Thanks, again, for the help response.

Imac won't start unless I unplug it

I've had my imac for about a year and a half, and ever since I got it, when I shut it down, I have to unplug the cord, wait approx. 30 sec, then replug it before it would turn on. I avoid this by always putting my computer to sleep. When I restart, it works fine, but when I shut it down, I have to unplug it before it will boot up.
We just moved to a house that has a very low amp breaker box, and a couple times the breaker flipped when I tried to use another machine on the same breaker. This happened just last night, and I unplugged the computer, let it sit all night, and it still wouldn't boot this morning. (It turns on, but just shows the gray screen and sits there.) We've been running off of an external HD because our internal drive was experiencing an irreparable failure. I finally turned off the external and turned it back on. Then it booted up.
I'm really tired of this happening. Can anybody tell me what I can do to fix this problem?

My new iMac has recently had OSX Lion installed on it and now when I start the machine it looks like its updating something every time, and the wireless doesn't work. So I restart and everything is OK - until I have to start up again the next time?

My new iMac has recently had OSX Lion installed on it and now when I start the machine it looks like its updating something every time, and the wireless doesn't work. So I restart and everything is OK - until I have to start up again the next time - then I have to repeat this again! Any help appreciated.

I've been having the same issue, but have just discovered something on my own that hasn't been pointed out in any of the forums I've visited. In what I thought would be a vain attempt to help myself, I went to System Preferences, Users & Groups, and then clicked on Login Items. I discovered that one of the Items that was listed to open automatically upon login was iTunes Helper and that there was an exclamation point beside it indicating that it was incompatible. I simply deleted that item and now I don't have the situation you described and my wireless is connected. Hope this helps!

HT1296 My drive failed on my iMac and I had to get a new drive but now my iTunes music is gone including all the CD's I added to iTunes, and all of my custom Playlists. All of that stuff is still on my iPhone 4, but how do I get it all onto my iMac again?

My drive failed on my iMac and I had to get a new drive but now my iTunes music is gone including all the CD's I added to iTunes, and all of my custom Playlists. All of that stuff is still on my iPhone 4, but how do I get it all onto my iMac again? I have CD's on my phone that i no longer have the physical copies of so i can't just re-download them all, plus it would take forever! I just want to know if there is a way to get all of what is still on my phone, back over to my iMac with it's new drive and restore my full iTunes library to the iMac with playlists, CD downloaded music, and my iTunes bought stuff, so i can go back to synching the 2 devices without losing everything that's on my phone that used to be on both devices?

Judging by the numerous posts on here, there is a very good chance that the computer will not boot up.

The developer would know, at least they should help troubleshooting.

To use the features in iCloud you need to upgrade to 10.7.3 (Lion).

HT1423 i am replacing ram in an early 2009 imac. easy - right? but the pulling on the tabs didn't work. i have had the ram sticks out before; but now they don't budge. should i apply more pressure? use a tool to pull harder? will the tabs break off?

sorry for the format - my 1st question...

thanks Kappy.
the computer has beem working for years after my 1st ram removal; but i may have pushed them back too hard. i did pull firmly - tried pulling up slightly; tried tugging on the sides of the stick; pulling in pulses. the only thing i have not tried is using needle nose plyers with protection on the tab film itself.
have you had the pulling harder ever work? or break the tab?

HT1267 how do i sync my iphone with my new imac? i had it synced to a macbook before.

Hi,
Give this a try:
First, connect your phone to your MacBook and let it backup to save your data on your Mac. (How to back up)
Next, copy your iTunes library folder to your new iMac. The location: Macintosh HD/user/music/iTunes
Your applications can be downloaded again for free. Downloading past purchases.
Hope this helps and let me know how it goes.

HT3199 I have an apple TV 1st generation - it froze downloading a trailer and had to be unplugged. Since then I cannot access the apple tv menu. When I run diagnostics it says it is operating properly but will not factory restore. What can I try?

Apologies, I was looking at the wrong schematic for the Apple TV 1. There isn't a button. So lets try this instead...
Remove the power cord and wait 20 seconds.
Plug it back in and let it boot (Give it 10 minutes, it's being tempremental)
Try and navigate to the the advanced menu and do a factory restore
If that doesn't work then if you are using the white remote hold down the menu button for six seconds and release this should bring up a hidden menu which will allow you to access the advanced configuration settings.
Again, if this fails there isn't much to do than tap it with a hammer to see if that fixes it (hard to believe how many times that actually works. (No responsibility taken if it breaks!, but at least you'd have a good reason to buy Apple TV 3)

My wifi goes down at least once a day and I have to unplug the time capsule and reboot it and then it works fine. Any idea why this is happening/what I can do to fix it?

I was having this problem while still using Mavericks -- it started after a Mavericks update last spring. During the initial Yosemite beta runs over the summer, it seemed to be fixed, but after the official launch in October, I had all sorts of problems keeping connected. Its gotten a little better, but still happens to at least one of my devices every day. Weird that we still cannot figure out why the connection keeps dropping on some devices, but not others, and then the next day, one of the devices that didn't disconnect the previous day will disconnect, but the ones that did disconnect, stay connected. It's just sloppy, poorly written software for technology that isn't working the way it should. If you turn off Continuity and Handoff on all your devices, you will probably see that everything stays connected. With those turned off on all devices, TC stayed connected to everything for over a month. The day I turned Continuity back on, all the problems started again. It had something to do with the bluetooth version being used, the wifi routine, and Apple's AirPlay technology not quite getting along with each other.

Hi I just got out of this situation after two weeks of forums and have tried any kind of different solutions.
If you have no response using start-up keys and you can't choose your start-up disk when pressing "Option" here is what to do.
The problem in this situation is common to users that install Boot Camp and at one stage the installation fail, may be a bug in BootCamp or just our mistakes, it doesn't really matter here is the solution.....
If you can start Windows, or Start the installation dvd of Windows do it, when In windows you will need to install BootCamp windows Driver, if you try to use the Apple downloaded file, it will not work.
You need to find the zip file in internet I found it with Google.
When you have the file run a "cmd" window with Administrator privileges.
Navigate in the folder that you have decompressed and open the folder Drivers/Apple/ you will see the file BootCamp.msi or BootCamp64.msi, of course choose the one that correspond to your Windows System .... type the file name and hit enter .... the drivers will install .... but what we really want to be install is that little icon on the system tray (right bottom).
After we will restart windows that little icon will give you the chance to restart the computer in OS X.
If something during the BootCamp and Windows installation had corrupted your OS X installation, you will have to reinstall, but at least you will be able to do it now. ;-) It took me two weeks and lot of researches, it's an hour job. Have fun.
