IPhone is 17 month old and shutting down when not connected to the mac any this I can do about it?

iPhone is 17 month old and shutting down when not connected to the mac any this I can do about it?
should I bring it to apple ?

Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these steps in order until the issue is resolved.
Replacing or even suggesting replacing hardware without doing basic troubleshooting first is not very smart.
If basic troubleshooting does not resolve, take it to Apple for evaluation. There is no obligation to pay for anything, the evaluation is free.

My MacBook Pro shuts down when i connect a USB cable.

My MacBook Pro shuts down when i connect a USB cable, only when its a 30 pin apple cable. Well one USB shuts it down and the other one doesn't work at all.
it only happens when i use an apple cable. It has no problem with my external drive nor with other things.
Ps. i did use different apple cables and they all shut it down.

What are you connecting? iPad, iPhone, what?
When you say a 30-pin Apple cable do you mean a Lightening to USB cable?
Little more info needed...

Have you reset the SMC and PRAM?

My older iMac running Mavericks 10.9.4 shuts down when it connects to the internet. Resetting the SMC doesn't help. What can I do?

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can read it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start Time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post."

My MacBook Air shuts down when its more than half way charged and won't turn on unless I plug it in to the adapter? Why is this happening and how can I fix it?

If you really do have a Mid 2013 Mac Air model then it is still in warranty, as the standard Apple warranty is one year from date of purchase. So take it into an Apple store and have it diagnosed and fixed under the warranty. There is some type of hardware problem that only Apple can fix.

ITunes shuts down when I connect my iPod 30gb

I desperately need help. Recently my computer crashes and I reformated it. So I had to reinstall iTunes. Ever since then iTunes shuts down when I connect my iPod 30gb. A windows error message appears saying iTunes has encountered a problem and needs to shut down. I am unable to update my iPod which drives me crazy. Somebody please help!
I browsed through some threads which have similar problems as I do, but I am unable to reply in any. It says: This topic has been archived - replies are not allowed.
There's this thread here about the problem I am facing but I doesn't seem to understand the solution to it.

Can somebody please help me?

A windows error message appears saying iTunes has encountered a problem and needs to shut down.
let's get a crash log from itunes, and send it to the Apple engineers for a look.
Typically, you'll need to configure Dr. Watson on your PC in order to generate crash logs. Windows start menu -> Run. Type in "cmd". Hit return. At the prompt in the command line window that comes up, type in
drwtsn32 -i
And hit return.
This will create crash logs in Documents And Settings\All Users\Application Data\Microsoft\Dr Watson\. There'll usually be a file in here called "drwtsn32.log"
prior to collecting the itunes crash log, delete any existing crash logs in there. (we want to make sure we send the correct crash log.)
Generate the crash, collect the crash log, and and send it as an attachment to this email address.
in the email to Roy, be sure to include the following information:
- A link to the thread on Apple Discussions where the issue is being discussed
- The username you are using in the thread
- The version of iTunes you are using or trying to use
- the version of Windows you are using (mention service packs)
- A concise description of the issue you are seeing
- The exact text of the error message you are seeing

My MAC Pro shuts down when the battery still have 50 minutes life.

My MAC Pro shuts down when the battery still has 52 minutes life without any warning. Does anyone have this problem? BTW, it is less than one year old.

You must have a MacBookPro, right? MacPro's are big desktop models.
Try the MacBookPro battery forum or their Usage forum.

My Ipod nano 6Th sometimes shuts down when I connect the phones, sometimes it not shuts down, but the volume and standby buttons do not work. If I not connect the phones everything works fine.

But the power/stand by button don´t. I need to disconect the phones to the power/stand by button starts to works. Anyone already have simmilar problem?

Hi shafi.shahzad,
I'm sorry to hear you are having issues with your new MacBook Air. Based on your description (issues with power management/charging, not retaining time settings, etc), you may want to try resetting your System Management Controller (SMC) and PRAM, as outlined in the following articles:
Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support
OS X Yosemite: Reset your computer’s PRAM

My MacBook air shuts down when Apple logo appears

Hey. My MacBook started to run slow and I forced a shut down and now when I try to start the mac, everytime it shuts down when the apple logo appears.
What can I do and i also haven't backed up any of my files and I really need that stuff.

If you really do have a Mid 2013 Mac Air model then it is still in warranty, as the standard Apple warranty is one year from date of purchase. So take it into an Apple store and have it diagnosed and fixed under the warranty. There is some type of hardware problem that only Apple can fix.

MAC AIR SHUTS DOWN WHILE STREAMING

My MacBook Air shuts down while streaming video. I am using safari and it works for a while but then shuts down and will not restart for quite some time. When it restarts I have to immediately close the video window or it will shut down again. I have the latest version of flashplayer.

This sounds like an overheating issue. Flash requires a surprisingly high level of resources. Do you hear your fans running at all while you are playing the videos?
Download the free iStat Pro widget directly from Apple:
http://www.apple.com/downloads/dashboard/status/istatpro.html
It will show you both your fan speeds and temperature. Start playing a video and let it play for a short while (sometime before it typically shuts off... but long enough to let things warm up). Then check the temp and fan speed. Do this while the video is still playing as things can cool off pretty fast after you stop playing the video. Post the numbers back here.

MacBook shuts down when not connected to power supply

Hey everyone, I'm making this topic for an issue that has gotten me edgy lately.
My MacBook (not new) has a habit on shutting down on me instantly for some reason when the MacBook is not plugged into charge. Here is the strange thing though, if I unplug the charger plug and set it still on my desk, I have more of a chance of the laptop not failing on me, but when I carry the MacBook around, it has a 90% (guestimate) chance of shutting down on me.
Even after having the laptop plugged in for 12 hours, the laptop just goes into suspend mode.
I have to wait a couple of seconds before I can turn it back on (by pressing the power button, not any key).
Also, when I shut down more programs at certain times when not plugged in, and having the screen brightness low, the Mac does not shut down so fast.
Any advice?!
Thanks

Could be you battery. Mine shuts down when showing 40% charge left and I have to plug it into the power supply to fix it. I found out it was the battery by downloading coconut battery. It's an application that allows you to check the status of your battery (Link at bottom). I suggest you get that and when your macbook shuts down again, plug it into the mains, start it up and run coconut battery. If it shows your nearly out of battery power then that's your problem.
I was showing 40% left when it shut down. Did the above and I had no power left. It happens when the battery is old about 250-400 loadcycles
Hope this helps.

Itunes keeps shutting down when I connect my IPod Classic

Itunes shuts down whenever I connect my IPOD classic and sync attempts to start. I have had this IPod for several years and I have had Windows 7 for over 6 months. I am trying to update versions, but I get an error message with that also.I have also seen posts on Microsoft and they aren't helpful.....I have seen many posts on Itunes also regarding same issue. What is up when the company will not fix their problems with the products?

I downloaded the 64bit system....did it like 3 times. Finally, I found some other helpful hints. I tried loading ITUNES in safe mode, still couldn't get it to not shutdown once I connected the IPod, I then logged into one of my other user accounts, then I was able to restore the settings, however, it removed all my songs and syned with the Itunes on that user acct (which was my nano IPod). That was ok, because then I was able to go back to my regular account and sync and updated all my songs....just had to have my kids authorize me again on Itunes. Think it's a racket to keep upgrading, changing things and not supporting the stuff that still works.....my classic works just fine nd holds 5,000 songs...I only have about 1500; so I have long way to go. When my display cracked and the LCD was all messed up. I sent it to IFIXIPODS fast.com and they replaced it, quick and cheap--hats off to them!

New Mac Pro shuts down when I put it to sleep?

I go to click my mouse of keyboard and nothing happens. I click the power button the back lights up and turns on as if it were off, what gives? This is brand new 64gb ram, 12 core, didn't even do a migration so it's all new stuff on here.

Hello Chief Sneed,
It sounds like your computer is going to sleep but when you later go to wake it up it will not turn on unless you press the power button and it looks to have shutdown at some point. I recommend checking to see if the computer is scheduled to shutdown at a certain time with the following article:
OS X Mavericks: Schedule your Mac to shut down or go to sleep automatically
http://support.apple.com/kb/PH13914
Schedule your Mac to turn on, turn off, go to sleep, or wake from sleep at specified times. You might do this if you want to be sure your Mac turns off when you aren’t working and turns on before you come to work.
Choose Apple menu > System Preferences, then click Energy Saver.
Click Schedule, then select the options you want to use.
To schedule a startup or wake time for your Mac, select the “Start up or wake” checkbox. Choose a day or group of days from the pop-up menu, then enter a time.
To schedule a shutdown, sleep, or restart time for your Mac, select the bottom checkbox and choose the appropriate option from the pop-up menu. Choose a day or group of days from the pop-up menu, then enter a time.
Thank you for using Apple Support Communities.
Take care,
Sterling
