4th Gen nano reboots but won't get past Apple logo, Hold switch trouble

I just got a used 4th gen nano for my son, when I charge it it lights up with the apple logo but nothing past that. I can press the menu and center buttons together to get into diagnostic mode, when I go into the IO test it says the hold switch is on when it's actually in the off position, and vice versa. However if I turn the switch on, so that the test says it's off, then it really does act like it's on and freezes up. Hence, I can't do anything other that get into diagnostic mode, I can never get to the music menu. Any advice???

Computer Turns on But doesn't get past Apple Logo and Spinning Dial

Hi everyone!
I totally stuck!
When I turn on my MacBook the normal chime sounds, the apple logo pops up, and the dial that constantly spins appears. But it never gets past that initial screen. I've tried letting it sit off for a few hours, taking out the battery, and trying to turn it on with the Power Adapter plugged in. I love my Mac and I'm very surprised by this.
If anyone knows how to fix this I would greatly appreciate it!

Welcome To  Discussions HSHS07!
To begin, run Repair Disk, and post the results.
THESE ARE THE STEPS FOR USING DISK UTILITY TO REPAIR YOUR HD
1.Insert the System Install disk, Mac OS X CD-ROM disk, or Restore DVD disk, then restart the computer while holding the C key. Use the System disk, of the OS, that is currently installed.
2.Once started up from CD or DVD, on the Menubar at the top of the screen, choose Utilities from the Installer contextual menu.
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from disc to access Disk Utility.
3.Click the First Aid tab.
4.Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5.Select your Mac OS X volume, if necessary.
6.Click Repair. If DU reports errors it has fixed, re-run Repair Disk until no errors are reported.
7.Repeat steps 5 & 6, but select the Hard Drive this time. It's usually the first listed with the manufacturer's model number. Make note of the S.M.A.R.T. status.
8.When finished, select Quit Disk Utility from the Installer menu.
9.Select Quit Installer from the Installer menu.
10.In the resulting pop-up window, choose restart.
11.After the computer has restarted, you can eject the CD.

IPad 2 won't get past apple logo and various other problems...

I knew I shouldn't have updated to iOS 8, my iPad was getting increasingly slower with each software update since I bought it a few years ago.
A few weeks ago the first problem arose - the home button suddenly became unresponsive. Initially it would work on about 1 in 10 clicks, but then nothing at all. I managed to get to settings to turn on accessibility features and the gestures to replace the home button so that wasn't much of problem, just annoying. I tried various things online that people claimed fixed this issue but nothing happened.
Then about a week ago it suddenly wouldn't wake up in the morning. I tried turning it on and it would get to the apple logo and stay there for a couple of minutes then go black again. I plugged it into iTunes and restored it etc hoping something would happen but of course nothing did.
And I obviously can't reset it on the device itself due to the home button being completely dead.
I left it for a few days then today I came back to it and tried to plug it into iTunes again and now iTunes won't recognise that it's plugged into my macbook at all.
Basically does anyone have any advice or should I just accept that it's dead at this stage and give up? Let me down gently!

IPad in a boot loop, won't get past Apple logo

Hi
My iPad 2 is stuck in a boot loop, doesn't get past the Apple logo. I've held the sleep/home button together many times and it hasn't worked. Tried to do a restore in DFU mode, goes all the way the end and starts rebooting again. Even tried re installing the firmware on it and it goes all the way to the end then starts rebooting again. Tried hitting it on the back and this didn't work. There has been no damage to the iPad.
Any other suggestions please?
Many thanks
Dominic

Thanks for the replies! Anyway, I gave DiskWarrior a try and it failed to work. The first time I tried it, I put the disc into the drive of my MacBook Pro and booted it from the disc. After going through the rebuild process it told me that due to a hard drive malfunction it couldn't append any changes to the drive. I then tried putting the disk into my iMac and used my MacBook Pro in Target Disk mode. This wouldn't even attempt to rebuild my drive saying that there was a hardware failure.
So, I booted into Windows 7 and saw that Windows was able to access the drive and read the files perfectly. All the files were in tact. I don't understand why disk warrior had a problem with it. Anyway, what I can do is reinstall Mac OS X Snow Leopard onto the hard drive again after moving the data onto an external hard drive using Windows. The only problem is that I would have to reinstall all of my programs while reimporting all of the settings and data that I can from the external hard drive. What I want to know is can I make an image of my hard drive (with SuperDuper?), and append that back onto my Mac's hard drive? Would that work again after reformatting the disk or would it just give me the same problems as before? Would it be better or easier to just start new and reinstall everything? Thanks!

MacBook Pro won't get past Apple logo during boot

Hey, recently while I was using on my MacBook Pro (note: just simply browsing the internet), the battery ran dry and the computer shut down almost immediately. When I plugged it in and turned on the computer again, the familiar Apple logo appeared and looked as though it would start up normally. However, an unfamiliar grey progress bar appeared and the usual grey gear started spinning. The progress bar looks as though it reaches up 10-15% completed but the computer just shuts down after that every time. I know it has nothing to do with the charge in the battery as I tried doing it plugged in and even waiting overnight for the battery to charge fully with the plug plugged in.
So, I tried using Disk Utility on the Snow Leopard Install disc (my original MacBook Pro install discs had Leopard on it so I just used the Snow Leopard discs instead). After using the "Verify Disk" command on the Macintosh HD volume, it stated that 'Invalid node structure' and then stated that the disk could not be verified and needed repair. I then proceeded with using 'Repair Disk' and it did say 'Volume repair complete' but then stated 'Updating boot support partitions for the volume as required.' This was when an error popped up and said "Error: Disk Utility can't repair this disk" and then told me to back up my files and reformat the disk.
I'm hoping that I don't have to reformat the disk as I haven't backed up in a while. I do have a separate partition on the hard drive that has Windows 7 on it that I can boot to. At least that means my hard drive hasn't completely died on me. However, I'm unsure what to do at this point to fix the computer. I tried to Safe Boot but it didn't change the outcome of start up.
Any ideas as to what I can do? I appreciate any help.

Won't start past apple logo, won't boot from install disc

mbp penryn 2.4 core 2 duo won't boot past apple logo. Running mtn lion 10.8... inserted Snow Leopard install disc, held down C key, only get a grey screen.Recently installed new HD, (seagate 750 Hybrid), upped ram from 2x2 to 2x4. All has been running very smoothly (and much cooler) for the past 3 weeks. Then this, prompted apparently by the mac going to sleep w/o being plugged in. Ran battery down, I suppose? Happens frequently.
Any suggestions?

ds,
"You might have ruined the RAM by handling it and touching the contacts.
Once you put new good RAM into the machine, reset SMC and PRAM then boot it up."
On the odd chance that I did ruin my ram I replaced w/ 4gb brand new ram, reset SMC and PRAM, then attempted to boot. Still a grey screen. Also re-attempted to put mbp into target mode, but no luck there either, nor with ejecting the Snow Leopard install disc via option/trackpad method, both on startup and while running, and no luck there either. I have a second Penryn mbp that I could salvage for a spare part if I knew what the problem might be. So far I get the idea from your responses that my machine SHOULD be rebooting, but for some reason isn't.
If this helps:
I hear, consistently on attempting startup, fans powering up, then two short whirrs as if a drive head is moving, then when the fans quiet down after 30-45 seconds, another short but different whirr, then only quiet fans and a grey screen.
Thanks in advance for any reply.

My iMac starts, but won't get past the loading screen?

My iMac starts up, but won't even get past the white screen with the Apple logo.
It kept giving me black screens, and would not start in safety mode. After command + option + p + r, the black screens stopped coming, but it still won't get past the loading screen, if I let it load long enough the Apple logo is replaced by a "denied" symbol but that is the only thing that happens. By hitting command + d, I was told nothing is wrong. When pressing command + r and going to disk utility, it found an issue while verifying and repairing. At first it stated "invalid journal" but now it only says to reinstall everything and that the problem couldn't be solved. I cannot mount the harddrive, and Time Machine just searches for copies without getting anywhere. When I try installing OS X (Mavericks) again, the harddrive doesn't even show up. What do I do?

The HD sounds like it has crashed, take it into your local Apple Store or Apple Authorized Service Provider (AASP), if you bought AppleCare this will be covered. If you don't have an Apple Store in your area and don't know of any AASPs then please click https://locate.apple.com/country to begin finding one.

IPod Nano Won't Boot Past Apple Logo...

Sup all?
...Got an interesting problem here. Replaced an LCD in a Nano for a friend, installation went smooth & without problems (or so I thought). After installation was complete, I put the Nano back together & started loadin' & playin music on the Nano. About 2 days later, I decided to update it w/the new iPod Updater (can't remember the date). Now the iPod Nano won't boot past the Apple Logo. I can tell that the "menu" has been loaded 'cuz you can hear the clickin' sound when you operate the wheel.
I've tried reformatting the iPod Nano (quick & full) & then trying to restore it, but it won't boot past the logo (after successful restoration?). Now I'm going to run the battery dead & then try to restore it again.
Any suggestions/comments on this?

The solution I see in your case is to go back and download an older iPod Updater.
See this link -> iPod Updaters
I suggest taking either the January 2006 iPod Updater, or March 2006 iPod Updater.
IMHO, Some of these freezing issues occur because of a fault in the latest iPod Updater.
I suggest going back to March (or January), and the nano could possibly work again for you.

IPhone 5 won't get past apple screen (keeps restarting)

Hello
Bought an iphone 5 just before the ios 7 release and for the last little while the phone would shut off a After a full charge when it hit approximately 97% of full charge it would shut off! Now it won't get past the apple screen and just keeps restarting over and over again.
Does anyone else have this problem with their iphone 5 and if so any solutions???
Our carrier Fido says this is an IOS 7 issue. Can anyone help
Thanks
Shep

Hey Shep77,
That definitely sounds frustrating! To completely isolate the issue, you may want to restore your iPhone in recovery mode, as outlined in this article:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/TS2802
iPhone is unresponsive and displays the Apple Logo
Review this article: iOS: Unable to update or restore.
.The above article also has great troubleshooting steps for Power issues, you may want to run through those if restoring does not resolve your issue:
Will not turn on, will not turn on unless connected to power, or unexpected power off
- Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
- Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion.
Learn about LCIs and corrosion.
- Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
- After at least 15 minutes, if:
               - The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
               - The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
               - Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
- If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
               - If the display turns on, go to step 4.
               - If the display remains black, go to next step.
- Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to
restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
- If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Thanks,
Matt M.

Mac Mini won't boot past Apple logo and spinning wheel

Hello,
I have a Mac mini (late 2009) running 10.8.2. Today, I tried to log into the computer. It accepted my username and password, but then the screen turned gray instead of logging in. I left it like that for about twenty minutes, then gave up on waiting and Ctrl-Command-Power rebooted it. It then wouldn't reboot: it gets to the Apple logo and spinning loading wheel, but won't go past there.
So I went into single-user mode and was able to access the HD fine. I ran a filesystems check using the recommended syntax (/sbin/fsck -fy, I think). It said that the volume looked okay, and that it had been modified. I took this as a good sign (that it had been repaired) and typed "reboot" to restart the machine. I held Command-Shift-V to perform a Verbose Safe Boot.
The computer makes no further progress after the following four lines:
vboxdrv: fAsync=0 offMin0x809 offMax=0x2bc3
VBoxDrv: version 3.2.12 r68302; IOCtl version 0x140001; IDC version 0x10000; dev major=34
VBoxFltDrv: version 3.2.12 r68302
VBoxAdpDrv: version 3.2.12 r68302
I'm assuming all the instances of "vbox" are in reference to Oracle's VirtualBox VM. I do have VirtualBox installed, but haven't used it in a while (months), so I don't see why it's suddenly causing a problem.
To clarify, the computer doesn't "hang" after these lines: I can still type text into the terminal. The entire log is being saved to /dev/console, so I could probably grab it from Single-User Mode if necessary.
Everything else seems to be working properly: even the wl0 drivers are loaded.
Does anyone have any suggestions about how to fix this, or at least disable VirtualBox so the computer can start?
Thanks!

Cult of Mac post:
When the Apple Logo appears your Mac has found a valid system disk, and Mac OS X begins loading.
Apple Logo with Spinning Gear
Once the spinning gear appears the BSD kernel (Darwin) has assumed command and begins loading device drivers. Shortly thereafter it transfers command to the almighty (and controversial) launchd process. Such are the workings of UNIX.
What this means for us mortals is that when a Mac stalls at the Apple logo or the logo with a spinning gear, it probably has a corrupt Mac OS X installation. It may also be having trouble accessing an internal or external hardware component, but this is less-likely.
Rebooting your Mac in Safe Mode can sometimes get things working well-enough that a second, normal reboot then works normally Hold down the Shift key at startup to boot in Safe Mode. DiskWarrior is also worth a shot (this is by far my most used disk utility). If that doesn’t work, an Archive & Install may be needed.

Iphone won't boot past apple logo

I'm the repair tech at my local radioshack and have a customer phone I can't figure out. When I attempt to power it on, I get the apple logo for 5 seconds, then nothing. I've attempted to put it into DFU mode, and attempted recovery mode, at no avail. I've even tried to boot into safe mode, and the same thing occurs. No matter the power source (wall/computer), I get the same results. Phone is out of warranty, so do not recommend that I bring it to apple - they won't help me here. Any ideas? I need the help!
iPhone 5s

I See a lot of those on my bench. The cause is the charge IC is burned out usually by a non Apple cable. The only way to get it to fully boot is to put a fresh charged battery in. Once a new fully charged battery is in it will continue to work fine including charging. But if you ever power off the device or it turns off due to dead battery it will not boot up on its own And you will need to swap batteries again.

IPhone 3G - Phone goes black and won't go past apple logo

I have an Iphone 3G... It will work fine and then the screen will go black... when I plug it in to the charger it will display the apple logo but will not cycle past the apple logo screen, then it will go black again and come back on and repeat this cycle. If I let it sit it will sometimes be able to cycle through and will allow me to restore... but without warning it will go black and I have to hope that I can get past the logo screen to do another reset. Does anyone have any ideas... is something internal shifting or is the battery getting old (screen shows full battery power) The back of the phone does seem warm. Please help... I took it to the genius' at the apple store and they were no help... only told me that it was out of warranty and I had to give up $199.00 for a new phone, not even for the 3GS, the same iphone 3G. I'd rather wait till June??? when the new Iphone comes out.

Well, it seems as though you answered your own question. While it is apparent the phone has an issue, since it is out of warranty, Apple will not replace it, except under their out of warranty replacement policy, which is the $199 they quoted you, and that is for a refurbished phone. The only other option I'm aware of it to try and force it to restore, read this article: http://support.apple.com/kb/HT1808
Since you are not willing to do the out of warranty replacement, which I can understand given the possible introduction of a new handset in the near future, if the article I linked for you doesn't work, you may have to live with a different phone for a short time.

Intel Imac won't get past Apple on startup

One of our 17" Intel Imacs (early to mid 2006 model) will not get past the Apple on startup. I have done the following:
1. Replaced the ram. No luck.
2. Zapped the PRAM. No luck.
3. Reset the SMC. No luck.
4. Tried booting from several CDs including disk warrior. No luck.
5. However, I was able to run the Hardware test from the system disk. It found no problems the several times I ran it.
6. I was able to mount the drive using Target Disk mode. I then ran diagnostics on the harddrive. Fixed some things, but nothing major. Still won't boot.
7. I tried the opposite approach and tried to run the machine using the other machine in Target mode. No luck.
8. I downloaded firmware, created a disk per apple's instructions and tried to run it. No luck.
I think that is basically it. I've been able to backup all the data and was going to reformat the harddrive, although I don't see how that would work considering that the machine won't boot up from either a CD or another drive in Target Disk mode.
I'm thinking this machine is a goner. Any other ideas would be much appreciated.

Have you tried the diagnostics? Insert the original OS X Installer Disc One that came with the computer and restart the computer. After the chime press and hold down the "D" key until the diagnostic screen appears. Run extended diagnostics and not any error codes reported.
If you cannot boot into the diagnostics then take the computer in for service.
