Weird clicking sound, iMac freezes or is dead slow, and turns itself off!
I've had my iMac for a good 3-4 years, during which it has been fitted with a new hard drive.
About a year ago, during watching DVDs, there was a weird click-clack sound for a good 10 seconds which was followed by the freeze. Sometimes it would go off, but sometimes the Mac would turn itself off like it had run out of juice. I thought it might've been a power issue.
Nowadays it almost every time presents this clicking sound, and freezing is inevitable. Sometimes there's no warning, the power just goes off. I have unplugged all devices that are using power ie. iPod, but the problem persists.
Could this be a mere power issue? What can the clicking sound be a symptom of?
I'm doing back-up in case the Mac completely shuts down, but I have hope for the machine yet!
I have few months warranty left, keen to sort this out pronto! All comments warmly welcome.

As I was making the clone with SuperDuper, the process was halted by an error, and I found half of my stuff copied on the external hard drive. It had enough space, but it prompted a dodgy file in 'Frameworks' in the Library which stopped the process. It all looked very benign, and I checked the troubleshooting and it suggested to try again after restarting.
What in fact had happened, was that ALL my music files had disappeared from my hard drive, none of my applications would work on my Mac, even Safari or iTunes, and I was left last night with the blue screen of death. These files were nowhere to be found, ANY of the hard drives.
Ready to chuck the piece.
Thanks for all your advice but this time, it made it worse. I'm getting the Mac a new hard drive as it's still under warranty. As it's the third time I've lost my files, there's hardly a scratch on me.. Taught me not to get attached to things too much.

Phone freezes and turn itself off when the "Ph. se...
I got a Nokia n97 mini 2 weeks ago and the phone works great except that sometimes it would turn itself off and when I turn it back on it lags and freezes. I notice every time the phone freezes and turn itself off when the "Ph. setup" in the App menu is running. Is the device updating itself? How can I make it stop? Everything freezes as soon as the Ph. setup starts running.
I try waiting it out (if the phone is setting something up it shouldn't take more than a few minutes) but I leave it there for several hours and it's still frozen.

My iphone 4s keeps freezing and turning itself off and the wifi option is now greyed out
My iphone 4s has been freezing and turning itself off and on for a few weeks now. I have reset it to factory settings and reinstalled everything, have updated the operating system but nothing seems to work. It was having problems connecting to wifi and when I tried to access the settings it freezes and can't find any connections. I have just updated the phone to 7.1 and now the wifi option is completely greyed out.
Your battery may have completely run down. When you connect it to power, leave it. It can take even up to an hour to get enough charge to get it to a useable state.
Although, I believe even fully drained, you should see some kind of indication on the screen of charging in progress, but it's very dim. -
Weird clicking sound every few seconds.
When i open the powerbook from being asleep, it starts up and everything is fine... every few seconds i hear a weird click sound, i'm guessing its the HD, and somthing is wrong with the moving parts. I have not dropped or damaged the powerbook in anyway. I first heard the noise when opening the top after being away few for an hour.
Has anyone else had a problem like this?With hard drives it's not a matter of if it will fail, it's when. Since they are made of moving parts generally when you begin to hear clicking noises, it's a sign to backup your stuff and then worry about running some diagnostics. If you have applecare you should run techtool and it should tell you with a small margin or error if it's good. Now just because it says that the drive is still good can also not mean that it isn't in the process of going bad. So, keep a good backup of all your stuff on an external drive. I use superduper to do a full backup of my system once a week on a external firewire drive that's bootable if i need it. It will do a "smart update" of your data when you backup after the first time saving you a lot of time.
If you don't have applecare, try and find a friend that does or take your computer to your local apple authorized service center. They will have access to the gsx (global service exchange) website which has specific diagnostic bootable cd's for each model of computer. They should be able to tell you if it's bad or not. If you find a friend that has applecare, just use his techtool cd. Just Boot from the cd and run the diagnostics, don't install the app on your mac as that would be illegal.
Hope this helps

Freezing screen with weird clicking sound to follow
My MacBook keeps freezing with almost every action I do with it including navigating the internet. It freezes for periods of time and makes this weird clicking sound that stops when my laptop starts working again, does anyone know what could be wrong with it? I've had to reset it once since it wouldn't turn on after the chime. Some one please help!
If you have AppleCare it is two years ........ then

I might just be making a big deal out of a small thing. But I noticed a couple of days ago the mouse pad on my macbook makings a weird clicking sound prior to me clicking down on it. When I slightly touch the mouse bar there is the annoying clicking sound. Is it a broken spring or something? Does anybody know what I'm talking about and what I should do about it?
This is a very common issue. It will not cause any harm, but if it really bothers you then take it to the apple store. Some people take out the battery, and put a folded up piece of paper on the underside of the tracpad button, then replace the battery on top of it. I have heard this helps, but I have never tried it because I rarely use my button, I just tap the trackpad.

IMac turned itself off and won't fully turn back on
My iMac turned itself off this morning; all I was doing was typing, nothing intensive. It wouldn't turn back on.
I first got a wired keyboard and mouse and tried resetting the SMC. No success.
Next I took out and put back in the RAM (and it was unplugged). After repeatedly pressing the power button, I got a single beep out of it. I personally don't think it was high enough of a pitch, but I read that it might've been because the computer didn't read any RAM.
I might've again taken the RAM out, this time also unplugged. After more repeated pressing, the fans came on, but then dead again.
The third time, the fans came on and half of the dong played, but it was cut off.
The forth time the dong fully played, but a second after, it turned off again.
All of these times involved unplugging the computer for a few seconds and then repeatedly pressing the power button; I might've taken the RAM out all of the times too, but I don't remember now.
Two or so weeks ago, I did have a kernal panic while I was editing in iPhoto, and I believe it's the first for my iMac. About a month and a half ago I had a graphics problem where using exposé to show all windows caused the whole screen to become jagged 'shards' of colour (it reminded me of broken pieces of glass). While a restart fixed both of these problems, the graphic problems are not new for this iMac (though I had never had the shard effect before).
Two more little things that I'm unsure if they're related: last night, it turned itself on from sleep, but it does this every other night, so I don't think last night's special; and every time I got it to turn on, I felt that I had to give the power button just a short burst of force, as if holding it for even half a second wouldn't get it to turn on.
Does this sound like the logic board, or less expensively, the power supply? Since it attempts to come on here and there but gets cut off, what does that say with respect to the logic board?
The computer turned one year in August 08, and there's no AppleCare. Even though the warranty's gone, would Apple have any negative view if I opened it up to get my HDD? I can get the screen off with three house suction cups; my HDD was last backed up four days ago, and of course, I had just typed about 3000 words for a story I'm working on between last night and this morning.
And lastly, if I make an appointment with the Apple Store (two hours from here...) and they want to take it in, will they take out my HDD right there and give it to me if I don't take it out? Four days is so tremendous in this situation. I will not part with my HDD.Perhaps. While I guess they're certified, I still trust Apple the most. Also, if it is a logic board problem, and it is widespread, hopefully this could be free. I don't know how a reseller would handle such a situation. I just want a file off my HDD!
I can confirm that it never really powers on unless it's been unplugged for at least a few seconds. So far, the longer it's been unplugged, the longer it stayed on. There were hours between the times I almost got into my account, and then the login window.
I again switched the MacBook and iMac's RAM, but doing this makes a senseless result. The MB's light simply stays on (no fans or screen, but when I turn it off, I do hear it 'de-whir'), and the iMac just quickly turns on and then off, as it has been after a 5-30 second unplugging session.
I guess this is the rebellion of a Revision A machine. -
I have a 5 month old iMac running Lion and W7 with the latest version of boot camp . It has been operating flawlessly until I went to reboot into Mac tonight. Screen went black, and system is unresponsive. I've tried force quitting and turning power off. Hard drive starts, there's a small amount of drive activity and that's it.
Hi Jane, your info may still be there, look in the Users folder at root of the drive, how many users are there there?
It sounds like this may have happened...

Frustratingly, since I upgraded to Yosemite 10.10, I too am having the worst problems with WiFi dropping out. I've never had this problem before on my iMac 27-inch mid 2011 model. Turning WiFi off and then back on again sometimes works. Help please. I've already tried a lot of your suggested fixes, but without success. Why hasn't Apple Fixed this?
Please test after taking each of the following steps that you haven't already tried. Stop when the problem is resolved. Back up all data before making any changes.
Step 1
Take the applicable steps in this support article. The Wireless Diagnostics program generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Step 2
Disconnect all USB 3 devices. If you don't know which are USB 3, disconnect all USB devices except keyboard and mouse.
Step 3
If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. If you find that Wi-Fi works better with Bluetooth disabled, you should use the 5 GHz Wi-Fi band. Your router may not support it; in that case, you need a new router.
Step 4
Open the Energy Saver pane in System Preferences and unlock the settings, if necessary. Select the Power Adapter tab, if there is one. Uncheck the box marked
Wake for Wi-Fi network access
if it's checked.
Step 5
Open the Network pane in System Preferences and make a note of your settings in the Wi-Fi service. It may be helpful to take screenshots of the various tabs in the preference pane. If the preference pane is locked, unlock it by clicking the padlock icon and entering your administrator password. Delete Wi-Fi from the service list on the left by selecting it and clicking the minus-sign button at the bottom. Then recreate the service by clicking the plus-sign button and following the prompts.
Step 6
In the Wi-Fi settings, select
Advanced... ▹ TCP/IP ▹ Configure IPv6: Link-local
Click OK and then Apply.
Step 7
Reset the System Management Controller.
Step 8
Reset the PRAM.
Step 9
Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
Step 10
Make a "Genius" appointment at an Apple Store, or go to another authorized service center. -
IMac turns itself off during start up
On a 27" iMac I installed the Yosemite 10.10.1 upgrade from the App Store and on restart it turns itself off after the logo and gear are on screen. Unit will not start in safe mode. Now what???
Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Can someone help me?How do I take the zoom feature off my MacBook Pro? I have already went to System Preferences and turned "zoom" off in the Universal Access. I saw where someone said to use THREE fingers to double click... ??? Double click what? And 3 fingers?
What really cheeses me off here is that Apple isn't allowing users enough customization. With each update of iTunes (and the OS and iOS) we're forced to give up something that worked well for the way we want to use the app and make do with fewer (and lamer) options. If Apple keeps this up, they're going to start losing customers fast. I mean if this isn't fixed soon, I'm pretty sure I'm going to give up on iTunes, and then I'll probably go ahead and get a Galaxy when I need to replace my iPhone.
What I don't understand about how they won't let users delete the list of available podcasts now is why? How is this making it a better program? I can understand that not all users are capable enough to right-click on a feed and select "Show all available episodes", so I can see why they want the complete list to be the default (and, surprise, it already was). But to not give users the option to delete that list? It's inconsiderate because it makes navigating feeds with a large back catalogue really frustrating. I'm flabbergasted that no one at Apple considered all the podcast feeds that keep hundreds of episodes available when they removed this feature. It smacks of rank incompetence.
What improvement were they trying to make here anyway? There was nothing wrong to my mind about how podcasts were managed in previous versions. Whatever improvement they were trying to make here, they should have realized that many users would at least want the option to keep things the way they were.
And reverting to a previous version is no solution. I can't sync my iPhone with the new iOS without this update, and (while I do have some issues--specifically how you can't play podcasts in the Music app anymore) I do like the new iOS. -
Hello, I downloaded an ntfs systemfile from tuxera and used it to convert a usb stick so I could put more than the fat32 4gb on, my Imac froze a while after so I turned it off the on and now I have blue vertical lines on boot up and the a white screen with lots of tine blue symbols after, mouse pointer moves but thats about it.
Have used R and cmd to get a menu up but once I choose one of the four options my mouse is rendered useless and I cant get any further, have downloaded, to another usb stick recovery disk assisstant and am trying to use that in conjunction with the lion option on the previously mentioned screen, computer was responding really slowly and has now frozen on the terms of software license agreement (maybe the last hurdle!) can anyone pleeeeeease help!!!!!??????It's likely that the boot drive is failing, or that there's some other hardware fault.

My ht-ct80 sound bar keeps turning itself off every 15min.
4 days ago I bought a htct80 sound bar and it keeps turning itself off every 15min. I serched the internet for a solution to no avail. So I need a answer from sony. Its a great sound bar while its on. Please give me a solution or i will have to take it back for a refund this weekend. If anyone else is having this ptoblem. And i know there are many please reply to this post. The more that reply the more likely we will get a rwsponse from sony.
Hello everyone,
The Sound Bar turning off every 15minutes is related to the Auto Standby function due to the Sound Bar not receiving an input signal. Unfortunately, there are two conditions where the sound bar will recieve a low input signal that results in the Auto Standby triggering incorrectly.
The first case is when the TV’s headphone jack serves as an audio output jack. This is not a recommended method for Audio Input for the Soundbar. If you are using this method, check the TV’s audio output settings. For details, refer to the TV’s operating instructions. If you can not change audio output setting, set up TV volume which is strong enough to prevent it from entering Standby mode.
The second case is when you are using a set-top box (Cable box) that has a volume setting. You can either change the Audio Settings on the set-top box for Fixed Audio Out (if available) or increase the volume on the set top box(Cable box) to maximum setting and then adjust the volume on the Sound Bar itself to obtain the desired actual volume.
Thank you,
---Chris
