IMac acting strange now won't start only 3 months old

This has just happened. Whilst doing some encoding a message suddenly appeared saying I had to restart. Everything had sort of froze. So I restart and get to the apple logo but then a grey screen comes down saying restart again and big lines of code appear.
Straight away booked in for genius appointment but that's not till wednesday. Anyone know what's happened?it's a 24" iMac. 4 g ram. Only 4 months old.
Before this I've noticed other little things like apps not responding and the famous beachball. Not to good for a £1200 mac!!!

Anyone know what's happened?
There would be no way anyone here would know.
Not to good for a £1200 mac!!!
Technology is far from perfect. Then take it in for warranty repair.

Strange email problem; it started only loading unread emails, but from 3 months ago. It is now loading new emails too, but no emails in the past month, read or unread. It's gmail, set up through the phone, I've restarted restored

Strange email problem; it started only loading unread emails, but from 3 months ago. It is now loading new emails too, but no emails in the past month, read or unread. It's gmail, set up through the phone, I've restarted restored and updated firmware, deleted the account, anything I could think of, but it's just not accurately downloading the most recent emails.

The answer is very simple: You were not the original owner of the phone. Target sold you a phone that had been returned. You can verify the date of the original sale here: Apple - Support - Check Your Service and Support Coverage. I suspect you will find that the warranty expiration date is not one year from the date that you bought it.

SNOW iMAC DV 500 mHz won't start

I upgraded to 4.1.9 and installed 10.4.6 so I could run new software.
Worked fine until several Power failures by Edison this week. Now will not restart from the button on front; not even a tone; just a click and flash of light sometimes.
Acts like a latching relay isn't pulling in. I changed to new 3.6 v 1/2 AA battery; zapped all the things listed and still not even a flicker from the screen; sound from the drive; etc.
thanks for help

IMac G3 600 OS 10.4.10 won't start-only BLUE SCREEN?

I have an iMac G3 slot-loader 600 Graphite with 10.4.10 768 MB RAM 40Gig HD. It failes to start up. I get the white screen with the Apple logo and the small spinning sprocket. After 5 minutes, it goes to a BLUE SCREEN with the spinning sproket, then after 5 more minutes the mouse cursor appears only. You can move the cursor around the BLUE SCREEN. Tested RAM from another machine, and battery reads 3.7 volts.
Thanks!

Well, I'd try powering on with the shift key held down. This boots in safe mode which will run repair disk and skip loading of some software.

IMac 233 1998, upgraded to OSX, brownout, now won't start up.

Hello. Our bicycle collective received a gift of a 1998 Blue iMac, I believe it's the 233 MHz, not sure if it's regular or 233/B.
It came with OS 8.5. Most unwisely someone decided to install OSX 10.1.5 without researching it beforehand. It ran the OSX for a while until a circuit breaker lost power. Since then the iMac won't start from either the keyboard power button or the computer power button.
I believe it came with 4 gigs of hard drive space, is this enough for OSX? Should we get an external USB hard drive?
I'll be back there tonight to check it out, I found out about the reset button and I'll try that.
Does anyone have any suggestions.
The specs on the iMac when we got it:
OS 8.5
Two memory slots currently 32+128 + 160 megs memory
CD only tray
Production date 11/28/1998.
Also has a built in modem (I'm assuming a standard 56k modem hard wired - can this be converted to wifi?)
2 (two) USB slots and a firewire(?)some other small square input slot.
Thanks,
Arthur

Hi,
First where are you located?
Then you should go here for info on your machine:
http://www.lowendmac.com/imacs/index.shtml
depending on if it's a rev A or B. I think you can tell by looking at the graphics chip.
As to the startup issue:
"Logic Board Battery
The battery on the logic board controls the stored system settings,
such as date and time. It is important to note that the battery does
not affect power at startup."
but then in manuals for the slot loaders they said to check the battery if there were dead at start up issues. Hee hee.
Also:
"The Cuda Chip
The Cuda is a microcontroller chip. Its function is to:
• Turn system power on and off.
• Manage system resets from various commands.
• Maintain parameter RAM (PRAM).
• Manage the real-time clock.
Many system problems can be resolved by resetting the Cuda chip
(see the Symptom/Cure tables for examples). Press the Cuda
reset button on the logic board to reset the Cuda chip. (The Cuda
reset button is located on the back edge of the logic board between
the modem port and the processor module. Refer to the Logic Board
Diagram in the Basics chapter for location information.) If you
continue to experience system problems, refer to “Resetting the
Logic Board” later in this chapter.
Troubleshooting General/ Resetting the Logic Board - 11
Resetting the Logic Board
Resetting the logic board can resolve many system problems (see
the Symptom/Cure tables for examples). Whenever you have a
unit that fails to power up, you should follow this procedure
before replacing any modules.
1. Unplug the computer.
2. Disconnect the cable that runs from the power supply to the
power filter board on the bottom side of the logic board/mass
storage chassis.
3. Press the Power On button on the front of the unit.
4. Remove the logic board/mass storage chassis from the unit.
5. Remove the battery from the logic board.
6. Wait at least 10 minutes before replacing the battery.
7. Make sure the battery is installed in the correct +/-
direction.
8. Reassemble the computer and test the unit.
Note:
This procedure resets the computer’s PRAM. Be sure to
check the computer’s time/date and other system parameter
settings afterwards."

IMac Summer 2000 G3 won't start up. No green light!

Our beloved old iMac (listed below) has simply died on us. The green power light won't light up and we get no sound when it's pressed, nothing. At first it blinked then shut down and now won't blink anymore. All I get is a blank screen as if no power was booting up. A power cable check and replacement didn't help.
Recent history: We frequently got problems with the date and time. I had always isolated that issue as a weak PRAM battery. We got an error message that the date was wrong i.e., Jan 1 1971. An attempt to correct it didn't help. The error message said that the PMU needed to be updated. We downloaded some Apple software but it turned out it was for 0S 9. Yesterday we had some issues such as the iMac wouldn't shut down and woud suddenly go to sleep instead. Then today it just wouldn't start up, period.
My suspicion is it's either the power supply or the PRAM battery. But the battery is only 2 years old and normally their life span is longer than that. I have an old Mac IIVX with a PRAM battery I can dig out of it. This is my first workaround.
I know others here have recently posted similar problems and this may sound redundant, but I'm doing the workaround and will post the results. If anyone can conjecture on this battery issue or if that fails and you think it's the power supply then please let know where I can get a new one. Otherwise I'm going to try to find one on Ebay.
Thanks

James,
Thanks for the update. Was the quote from an apple authorized dealer? <--
I was quoting in euroes which is higher than dollars. I'm not sure what the euro to dollar rate is now but the dollar is pretty weak. I live in Europe, shoulda mentioned that. The weak dollar keeps all Apple products relatively low and has for the past decade or so. And yes it was a local authorized Apple dealer, not a box store. I've looked at them and their prices are a bit higher and you don't get the reliable warranty service. They've got the Apple trademark selling area but walk a few yards and you can get a Dell. I think Apple rents them the space, but most people I know buy at authorized Apple dealers where you can customize your order and have good service on warranty. I don't have an official Apple Store here, I wish I did but sofar there aren't any in continental Europe I know of. Maybe one in London.
For the iMac G5 17in 1.83 MHz with 512MB RAM 160GB HD and no Superdrive the asking retail price is around 979 euroes. The 2MHz Core Duo with 1GB RAM, Superdrive and two FireWire 800 ports goes for around 1,117 euroes. The 20in starts around 1,300 euroes.
Also have you thought of replacing the board yourself? <--
My wife just shrugged and decided to break down and shop for a new one. It's too much bother to do a DIY repair that big. We figured we could salvage some of it for its parts and resell them on eBay. I stole some RAM and the fresh PRAM battery out of it for my G4. The HD will be removed and wiped. Maybe resold. I've seen a G3 motherboard on eBay but you don't know what you're getting. I stop at buying used RAM and power supply units.
Post a new post for instructions and parts locators if interested. <--
eBay USA has a full range of Mac parts. I saw a G3/G4 power supply unit that was going unsold for $12 today. Could use that to fix up the Blue and White but the shipping to Europe is $35 and I can buy one here on eBay for 45 euroes plus shipping.
Thanks,
Rob

Water on MacBook now won't start

Water and fizzy drink went on it and now it won't start. It ran for a bit but now zip. Any ideas?
It was only a bit.

ASAP make a Genius Appointment and take it in for service. Expect an costly bill for the repairs which will probably require a motherboard replacement at best.

Now continue to hold the home button while you plug it in via usb. It will enter "recovery mode" and will show a connect to iTunes screen.

Tried to restart on os 9, now won't start up at all

I have an old G4 desktop with OS 9.0. I bought OS 10.4.6 and installed it fine, not erasing the hard drive.
I discovered that Classic can't work unless you have 9.1 or preferably 9.2 or later, so I went and downloaded a 9.1 upgrade (intending to later get a 9.2 upgrade too). Then I went and tried to restart in 9.0 so that I could install the 9.1 upgrade, but now the computer won't start up at all.
If I hold down opt during start-up, a screen appears with three icons: a circular arrow, a hard disk w/ little Finder icon, and a right arrow.
What do I do? And is there a way NOT to erase my hard drive, or is it too late for that?
Thanks for any help... and please be detailed in responses because I don't know much about these sorts of things.

OSX Yosemite 10.10.3 freeze during installation now won't start up help!

When updating to OS X Yosemite 10.10.3 the installation process freezed up with 1 min left. I waited few hours and decided to shutdown my Macbook Pro with the power button and waited 30 sec to power back on, but my Mac won't start up! You see the apple logo and a progress bar for 2 min and than a black screen with sometimes a spinner rotating and disappearing again showing the cursor back and forth. I turned it back off and need some advice from someone what to do next!
Please can someone help me with this!?

I solved the problem myself. This is what i did:
First i restart in safe mode:
Turn off you Mac wait 10 sec
Press on the on/off button
Keep the Shift-key pushed in when you hear the startup sound, not before that!
Let go of the shift-key when you see the Apple-logo on the screen
Next:
Wait until progress bar is done and the Mac starts up in safe mode.The system feels unstable, but ignore that for now.
Go into Apple Store and make sure that are no updates left to install if the are install them.
Then go into Disk-utility and check your Macintosh HD on faults.
If something turns up wrong with your HD close Disk-utility and shut down your mac (make sure any updates are done).
Now we going to repair HD:
Startup your mac
And directly keep pressing COMMAND + R keys until you see the Apple-logo appear then release them.
You will see some options and go into Disk-utility and select your Macintosh HD second one down and repair the disk and wait until done.
If everything is repaired correctly you can restart you mac, done..

IPad 2 is won't start only showing the apple sign

Hi,
my iPad2 died on me. It was very low in battery, so I started charging it. Everything looked fine until the apple sign came up. And that is it. It won't start. It doesn't connect to iTunes and re-start doesn't work either. Any suggestions? Thanks for all help!

BTW - it doesn't seem to charge either. Apple sign only comes up while connected to power output (and trying to re-start), when I disconnect and try to re-start I get the "low battery - connect to power" sign - even though the iPad has been connected for several hours.

IMac 20in intel2.66gh won't start up!

My iMac 20in intel 2.66gh won't start up. When I turn the power on the screen stays black and a tone sounds 1-3 times at approx 2 second intervals. Does any one have any solutions I can try before I pack it up and take to my nearest apple store. Thanks. Merilee

Could be a RAM problem: http://support.apple.com/kb/HT5860?viewlocale=en_US
Before taking it to the workshop, you could try unplugging the modules, cleaning the RAM bay with a vacuum cleaner and then re-seating the chips. It's an easy thing to do - Youtube has plenty of 'How to's'. Make sure the Mac is switched off and unplugged first.

27" iMac 3.2 i7 won't start. Emits 3 'beeps', pause, repeats.

My 27" iMac 3.2 i7, 20GB RAM won't start. Emits 3 beeps, pause, 3 beeps, pause.

Here's a link to an Apple support page that describes the possible Startup tones.
Mac computers: About startup tones - Apple Support
The short answer is here. Looks like your RAM is bad.
1 tone, repeating every 5 seconds: This indicates no RAM is installed.
3 successive tones, a 5 second pause (repeating): This indicates RAM does not pass a data integrity check.
1 long tone while holding down the power button: Indicates an EFI ROM update is in progress on a computer manufactured before 2012.
3 long tones, 3 short tones, 3 long tones: Indicates EFI ROM corruption is detected and the computer is in EFI ROM recovery mode.

HELP! My Mother in Law's IMAC - OS 10.3 won't start in safe mode!

She had a power outage last night, with the computer on. She just gets a screen with the apple and spinning gear. We can't start it in safe mode or with the install disc. She got something when we started up in single user mode, but she said there was no place to type in any commands - just lots of writing that does not make sense to us. PLEASE HELP!!!!!!

sciteacher77:
Here are three articles from Apple's Knowledge base dealing with different startup issues. Look through the first two and see if they offer any help. Then go to the third and see if you can get it to work.
Your Mac won't start up in Mac OS X (Mac OS X 10.3.9 or earlier)
A flashing question mark appears when you start your Mac
Resolve startup issues and perform disk maintenance with Disk Utility and fsck
Good luck.
