My Mac won't turn back on after I updated the software
My Mac won't turn on
Pull your hard drives.
Put in your OEM DVD
Hold down the letter d on startup and run Apple Hardware Test
Put in your latest OS X DVD and hold c
Does it do both.
Oh, and Reset SMC.

And make sure you have backups, bootable backups, and just WHAT version OS X?? what update(s)?
.... we are not going to know.... Lion? 10.6.8?

My phone keeps shutting down approx every 5-10min for about a minute then it turns back on itself. I have updated the software so thats not the issue, any suggestions?
Do you have a case on the iPhone or have you damaged it in anyway? If you have a case, try testing without the case.
Also, try restoring the iPhone and testing it as a new device.
If that doesn't take care of it, get a Genius to take a look at it or setup service online. -
My iPhone 4S won't turn back on after I do the reset
Somehow my iPhone won't charged and I decide to turn off but now I can't turn it back on again... I try everything but still not working...
Reset, hold both the Home and Power buttons for about 10 seconds until the iPhone begins to start. If still problem, and your decide to Restore your iPhone, try DFU Mode Restore. Open iTunes on computer. Connect iPhone to computer with USB cable. Hold both Home and Power button, after exactly 10 seconds release the Power Button, keep holding the Home button until iTunes recognizes iPhone in Recovery Mode, usually about 20 seconds time.

today my mac won't turn on at all...the light at the front is remaining on and at a constant brightness however the screen is still black! I'm not sure what to do next?
If you can log in blindly or using the flashlight method, it is possible your screen brightness somehow got set all the way to nothing. I don't have my Macbook with me right now to test it out but I believe it may not be possible to adjust the brightness at the log-in screen so you have to be able to log in first (though I could be wrong on that).

I have an iMac running OX 10.5.8
I need a portable external hard drive to back it up before updating the software to Yosemite but I can't find anything that doesn't require you to be running at least OX 10.6. Is there a suitable hard drive? I'm not very technical and wouldn't know how to do any formatting so I want it to be very basic so that I can just plug it in. 500GB should be more than adequate.Correct. When you purchase devices, they would have stated the OS they needed to work, on the box. This can be overlooked, but it is very important to check when purchasing.
You current OS, is so old, that they technology build into the new devices, is not something your OS understands. It didn't exist when your OS was created, and therefore you need to upgrade the OS to work with the newer technology of these devices.
10.6 software is not downloadable. You must purchase a DVD disc. You can order it from the on-line apple store

ITunes freezes on backing up iPad while updating the software to ios 8.
iTunes freezes on backing up iPad while updating the software to ios 8. Please help asap
Hi tac.sharma,
Welcome to the Apple Support Communities!
I know circumstances that keep you from updating your iPad can be frustrating. In this situation I would make sure your iPad is backed up to the iCloud, just to make sure your information is safe. After you have that backup, I would suggest following the steps in the attached article to help you through this update process with iTunes.
If you can't update or restore your iPhone, iPad, or iPod touch - Apple Support

My macbook that wont turn back on after I open the lid
Well my macbook is very fast and works great, *+when it turns back on+.* I leave it on most of the time and close it, plugged into a power cord, when i am done using it. I am not putting it to sleep or turning it off, just closing the lid. When I open the lid, it sometimes turns back on, and most of the time doesn't. The little light on the outside turns off when I open it, and when I close it, it turns on. I will push the power button, that doesn't do anything.
I will take the battery out and unplug it from the wall, put the battery back in and all, and it still wont turn back on. After I play with it for a few minutes, it will either turn back on, go to a grey screen with a grey progress bar, or pretend like I turned it on by going to the grey screen with the apple logo and the little spinning circle at the bottom. I have done disk utilities, any kind of utility i could think up, but it still does this. I was running tiger when it started happening.
I tried repartitioning the hard drive, backing everything up and reinstalling osx. still a problem. i recently upgraded to leopard. still a problem. I have no idea whats going on because it is not consistant. it will randomly do this. I have even sent it to apple and it wasnt fixed.It sounds like it's hardware-related. Note the exact time the events occur, and then check your system logs in your Console application for clues to the cause.
Try resetting your SMC.

If that does not work, you may need to get it looked at.

Display won't turn back on after battery dies
I have a Macbook Pro Intel Core i7 and am running OSX 10.7.5
Everytime I am using my computer and the battery dies, the display will not turn on after I plug it in again. I have tried to wait until the computer has charged up a good amount, but when I wake the computer back up after dying, the macbook startup sound plays and the LED light shines bright as if it were on, but no display. I have also tried click and pressing different buttons on the keyboard to see if this would wake it up, but no success. I have had to do hard restarts everytime this happens because it is the only way to get my display working again.
Any help is appreiciated. Thanks!Reset SMC.

My mac won't turn on again, it just shows the apple logo and some code
My mac was freezing up a bit while trying to get onto lanaboards.com so I decided to restart it. I figured i might as well update it at the same time. So i did that and chose the restart option that comes up when you update. It seemed like the update went through, but then it told me that it couldn't update but i was asked if i wanted to restart it, so i did. For some reason it didn't restart for a couple of minutes so i turned it off by pressing the on/off button. When i turned it back on it made the sound and then the grey background with the Apple logo appeared. Suddenly this code comes up using the word "panic" a couple of times. I'm not gonna type the whole thing cause it's kina long. It also says "Mac OS version: not yet set" (maybe cause i tried to update?) and "Kernel version: David Kernel version 12.2.1" It also says "debugger called: <panic>"
I won't be able to get it to the apple store for a week because everything closes down on thursday because of Easter and the buses seem to not go tomorrow and no one can drive me. I hope there's something i can do cause i have an important exam (100% of my grade) in two weeks so I'm freaking out a bit here. I also have some stuff due next week that just went up.
I really hope someone can help me, or at least know what may be the problem.
PS. I'm not 100% sure which operating system I have so i chose what i assume is the second newest iOS cause I know i have iOS at least
PS 2: My hard disc crashed about two months ago and was fixed at my local apple supplier, if that may have anything to do with the matter.you are not in MacBook Pro forum, so might be harder to swap out and replace hard drive but you should definitely have had them do that or even yourself.
Make sure you are at least using TimeMachine AND another backup method to clone your system drive so you always have a working 'spare' backup drive you can boot and work from - USB3 is good, TimeMachine even works decently for some on USB 2.0
Finding out why and troubleshooting a panic is a matter of trial and error after taking a look at what hardware, what software you installed (and some of which should be removed), even whether it is triggered by heat from processor or RAM (memory) errors, and memory errors can be triggered by software.

There’s trouble in my laptop paradise. I ended that with this caveat:
It’s much more comfortable to type on the 2011 model, with one big exception: the 2011 model runs much hotter.
I need more time to form a concrete opinion, but it seems so far that this CPU’s awesome performance definitely comes at a cost of increased heat and reduced battery life. For my intended usage as a desktop most of the time, that’s an acceptable tradeoff.
This turned out to be worse than I thought it would be, and today, the last day of my return period, I decided to return it and exchange it for a slower model.
The problem
Not only does the 2011 15” MacBook Pro run much hotter than previous generations, but as a result, the fans very frequently kick up to full speed (6200 RPM), greatly annoying anyone in the area who’s not wearing headphones.
I’ve done a lot of Google research and impromptu Twitter surveys, and this seems like a very common problem, exacerbated by a number of factors:
The quad-core i7 CPUs in the 15” run very hot, with a TDP of 45W, 10W higher than the previous dual-cores. Many people speculate that the 15” case and fan design just isn’t designed for CPUs that need this much cooling regularly.
The Core i7 CPU can use Intel’s Turbo Boost to dramatically overclock one CPU core to handle single-threaded loads whenever power and heat allow. It therefore hits its maximum TDP often when just one core is being maxed out, such as when Spotlight or Backblaze index new files, or when Time Machine is backing up.
The 2.2 and 2.3 GHz 15” models come with an AMD Radeon HD 6750M GPU, which adds significant heat. Modern 15” MacBook Pros dynamically switch between the low-powered Intel integrated GPU and the high-powered (and hot) AMD GPU as needed by applications, but the AMD GPU will always be used when an external monitor is connected — the Intel integrated GPU cannot output video over the Thunderbolt port in the 15”. (Oddly, it can in the 13” MacBook Pro and both MacBook Airs.)
It generates so much heat that it can’t be used in “clamshell mode” (closed, but with an external keyboard, mouse, and monitor attached), which has reduced airflow, without risking overheating, kernel panics, and possible long-term damage. I can’t see why Apple even enabled clamshell mode on it.
Some people report issues with the battery draining while playing a game. The 15” MacBook Pro comes with an 85W power adapter, but when stressing the CPU and GPU (such as when playing a game), the laptop draws about 93W — I don’t know enough about the electronics here to say for sure, but an insufficient power adapter capacity sounds like a plausible reason why the battery might drain under high computational load. If so, this is an embarrassing oversight by Apple.
The thermal paste seems to be very inconsistently applied, or there’s some other common manufacturing defect with the cooling system that varies per laptop. Many, many people reported having these issues and exchanging the laptop for a new one that shows far fewer issues. Many dedicated tinkerers have also reported success after reapplying the thermal compound between the CPU and heatsink, but that requires a very deep, warranty-voiding disassembly that I’m not comfortable doing. (I also haven’t owned thermal paste since 2001.)
Put simply, it sounds like the 2011 15” MacBook Pro has a lot of manufacturing inconsistencies and defects that result in improper cooling. But it also sounds like Apple wedged far too much power draw and heat into an enclosure that’s not designed to properly cool or power these demands. It’s not like Apple to release products like this.
But if I can get one working within my tolerances, it’s still the perfect computer for me right now. So I’m trying.
The attempted solution
Tonight, after requesting the return on my 2.3, I ordered a new, slower model that’s likely to run cooler with less fan noise. It’s the base-model 15”, but with an antiglare (matte) display added:
AMD Radeon HD 6490M: It’s manufactured on the same 40nm process as the 6750M, but has far less computational power, so I’m guessing this will result in much lower power consumption and heat.
2.0 GHz quad-core i7: This is the only CPU available with the 6490M. While I don’t expect it to be dramatically cooler-running than the 2.3 since it’s specced with the same 45W TDP, it does have a lower clock and lower Turbo Boost speeds, so I can probably expect an approximately proportional heat reduction.
So I’ll see what happens. I’m not sure what I’ll do if it doesn’t work out. This generation of 15” MacBook Pros has a lot of problems, and Apple really needs next year’s cooler-running Ivy Bridge processors as soon as possible.

i have updated the apple tv software (on one apple tv, ihave 2) after having used for 2 years withou any problem.
i tried to log in again to watch movies already purchased but i cannot. the itunes store is not available and the home sharing does not recognise my id and password. on my pc i have alsoupdate to the latest software my itunes.
the second apple tv where i am still resisting tomupdate the software works very well as always.
help!?Hi Everyone,
hope this message finds you all in time. The recent Apple TV update 5.1 is terrible. Apple knows it is which is why (thankfully for some relentless user -I have no idea who but I believe it was under threat) they have allowed to sign 5.0.2 again which means you can downgrade your Apple TV 2 and 3 to a 5.0.2 version via iTunes. Who knows how long they will keep the window open but I have downgraded my ATV early this morning. I couldn't post this earlier because I was out all day but I am doing it now.
Here's how to do it:
1) Connect your ATV to your computer via a Mini USB (not included with ATV but included with many other electronic devices) - in order for your ATV to appear in iTunes you must FIRST plug the USB cable to your computer and ATV and only THEN plug the power cable.
2) Download your ipsw restore file from Apple.
5.0.2 (ATV 2): AppleTV2,1_5.0.2_9B830_Restore.ipsw
5.0.2 (ATV 3): AppleTV3,1_5.0.2_9B830_Restore.ipsw
3) In iTunes select yout ATV, hold SHIFT and click on Restore
4) Find and choose the downloaded IPSW file in the Open Dialog Box and hit Next
5) As long as Apple still signs that version the Restore process will begin and will take a few minutes to complete.
Enjoy!

Laptop screen won't turn back on after being waked up from pm-suspend
I installed pm-utils and acpid to make my laptop sleep when the lid is shut.
To do this I altered my /etc/acpi/handler.sh to look like this
http://pastebin.com/9DgQQ30Z
Changing lines 57, 58 and 59 to:
button/lid)
#echo "LID switched!">/dev/tty5
/usr/sbin/pm-suspend
esac
The laptop suspends completely fine, and the power light turns from a solid light to flashing. But when I open the lid, the laptop wakes up fine, except for the screen which just stays completely black.
I can't do anything to get it back on, I even can't switch to any virtual terminals, forcing me to to a hard reboot.
This happens also when I just run "sudo pm-suspend" normally with the lid open and use the power button to wake back up. Wakes up fine except for the screen.First thing that would be helpful to know would be to know what kind of computer you have (e.g. model).
I actually had an identical problem with my laptop. It ended up being an issue with the wireless drivers included in the kernel. Ultimately had to blacklist them and install the ones from the vendor's website. Anyways, start with the model, and we can try to help you from there
