Mac OS X doesn't boot with iPod plugged in

Hi there,
i have a little problem with my ipod shuffle. When
start my iMac and my iPod is plugged in, then is
doesn't start or extremley slow. As soon as i plug it
out, it starts immeditely or continues. Is there
something i can do? or is it just again an issue or
bug from apple?
Thanks in advance
Yes... disconnect the Shuffle before booting. Your iMac is looking for a bootable system on the Shuffle (really...). It's neither an issue nor a bug, it's the way YOUR iMac works.

Imac won't boot with Ipod plugged in.

60gb 5G Ipod. Imac Intel Core2 duo 2.0 ghz.
About 80% of the time, if the Ipod is plugged in (through a USB hub), the Mac will only boot to a grey screen. As soon as I unplug the Ipod, the Apple appears on the Imac screen. My Iphone is plugged into the same USB hub at the time, with no similar behavior. I've tried restoring the Ipod with no change.
I've tried making sure that the startup disk pref pane is set correctly and locked, but for some reason, whenever I check it, its unlocked again. The Ipod does not appear there. I do have a clone of the startup disk attached to an always on external firewire drive.

Hello Mark
Having the iPod connected during the boot process is confusing the startup manager!
First try: *System Preferences / Startup Disk* and select the *Mac OS X, 10.5.4 on Macintosh HD* then *Click the lock to prevent further changes.*
You can also try ejecting the iPod be for shutting down or only sleeping the iMac when the iPod is charging!
Normally my iMac sleeps, but as a habit I always eject and disconnect all USB storage devices, iPods, cameras, flash drives, etc. be-for shutting down.

MBA doesn't boot with Ethernet plugged in /Startup disk ok

Hi everyone
My Macbook Air running OS X no longer boots when the ethernet cable (via USB adapter) is plugged in - it gets stuck at the grey screen. It starts booting as soon as I unplug it.
I have already reset the startup disk, but to no success...
Internet works fine when I plug it in after starting up.
Does anyone have another idea?
many thanks

Yes, it seems that it's a BIOS bug at least on T520, T420s and W520 laptops. Even in "Legacy" mode first stage bootloader doesn't execute if partition type is 0xEE (GPT).
Hope Lenovo developers will fix it. They fixed something on BIOS 1.31

Lenovo Thinkpad T520 doesn't boot with GPT slices on FreeBSD 9-BETA3 - BIOS bug?

Hi!
I've bought a brand new Lenovo Thinkpad T520 laptop and decided to install FreeBSD 9 Beta 3 following this guide.
But when I rebooted the system, it simply doesn't boot (turns out to the BIOS boot menu).
It's even doesn't boot with default FreeBSD 9 UFS-on-GPT installation scheme through bsdInstaller
Changing BIOS (latest, 1.31) settings BIOS Startup->UEFI/Legacy Boot from "Both" to "Legacy only" has no effect. As FreeBSD AFAIK doesn't support UEFI boot, legacy boot should work picking up and starting pmbr (protected MBR record), but it doesn't.
However, FreeBSD 9 UFS-on-MBR installation (with mbr boot record and FreeBSD slice in MBR partition instead of GPT) works fine.
It seems to me that UEFI/Legacy Boot "Legacy" setting actually has no effect if 0xEE type Primary partition entry is present on disk.
First of all, has anyone installed Linux or FreeBSD with GPT partitioning scheme on latest Thinkpads?
And the second one, as I've saw similar problem on FreeBSD forum thread about T420s laptop I believe that this may be a bug in the BIOS. How can I fill the bugreport or send an e-mail to support or developers, as, obvious, phone support can consult only about Windows OS.

Sawtooth won't boot with anything plugged into it.

My G4 450 won't boot with anything plugged into it at all. The power will go on but no boot. If I unplug everything (except the power cord) it will boot with a chime. Anyone know what the problem could be?

rs6er:
Well, it's likely to be a problem with the video card, the monitor, or the monitor cable. (I assume that this is your normal monitor which was just recently working on your Mac.)
Some thoughts... Have you tried reseating the video card? Does the monitor power on? Do you have another monitor and cable you can swap and try? Will it boot to Safe Mode ("s" key depressed at startup) with the monitor attached?

IMac will not boot with iPod connected

Hello everyone
I have a new iMac Core 2 Duo 17 inch 2.0 ghz and it seems to have a problem starting up when a 5th generation iPod is connected to the computer. When the computer is turned on with the iPod connected, the blank grey screen comes on, yet the apple logo or the spinning startup wheel does not appear. However, if the iPod is unplugged, it will startup as usual. Otherwise, there are no other problems with the computer or iPod.
I have attempted the following to resolve the issue, yet none of the aforementioned troubleshooting ideas have worked
- Reset the PRAM and the SMU
- Run Apple Hardware Test with no probems
- Reinstalled Mac OS Tiger and applications
- Reset the iPod and reimported songs onto iPod
- Enabled and disabled hard disk mode for iPod
I know that I can simply let the iPod be disconnected at startup; however, I feel like this should not have to be done with a new Apple product. Please let me know any other advice or if anyone has experienced the same issue.
Thanks!
Dave
iMac Core 2 Duo Mac OS X (10.4.8)

Have you reset your Startup Disk preference? If not, do so to see if that resolves your issue. It sounds as if your iMac is looking to try and boot from the iPod's disk.

Mac Book Pro doesn't boot (twice; after updating) and slow performance before these incidents

Hi,
Maybe someone can help me resolving a (re) boot issue with my Mac Book Pro. Last few weeks I experienced a tremendous drop in performance (start-up as well as handling and using applications).
Yesterday I downloaded and installed an app to clean stuff from the mac, such as binaries that aren't used, cache files, etc. It resulted in substantial better performance. Than, I used the updater on this application to update. This morning, the Mac wouldn't boot. After several attempts I used the old DVD with Mac OS X to re-install and boot. That worked.
Following this approach, I received two messages (that HP apps weren't secured or something and therefor disabled). Than I updated the Mac OS X and later this evening it asked me if I wanted to install some (4) other updates as well (don't know what updates these were). So I updated but now I am back at square one: My Mac doesn't boot. I do get the grey starting screen, but now even the 'apple' logo is missing.
Anyone else experiencing these problems and have any clues on how to fix it? By the way, I also tried to alter permissions on all files on the main hard drives (to ensure that I do not always have to sign off on updates and or changes of applications). Would that have caused problems?

You seem to have a lot going on here, so it's hard to know what's wrong. You likely had some underlying problems before doing the Software Update.
Here's a link that might help with the grey screen problem:
http://support.apple.com/kb/TS2570
Which app did you download?
If you can get booted up, check in the System Profiler to see that all of your RAM is recognized--if not, you may need to reseat one or both sticks.
If you can boot from your install disc, run the extended version of the Apple Hardware test to check for hardware problems. Freezing can be caused by a dying hard drive, which can also tend to corrupt software.
While booted from the install disc, navigate to Disk Utility and repair your boot disk. You can do this 2 or 3 times even if it says no problems found.
While in Disk Utility, check to see that the SMART status of your hard drive is verified. If not, you will need to replace the drive.
It probably wouldn't hurt to reinstall the OS.
Do you have a good, up to date backup? If not, it would be a good idea to make one as soon as you can, just to be on the safe side.
Have you tried a Safe Boot?

K9N Platinum - Doesn't boot with PWR2 connected

Hi,
I've just built a new PC with a K9N Platinum Motherboard (7250 Ver 1.0)
I immediately discovered a problem:
-If I connect to the power supply the PWR2 Molex (the additional power connector on the motherboard, to provide additional power to the video card) the system doesn't boot. Computer's LEDs get on for half a second, then it shuts down.
-If I deconnect the PWR2 connector, computer boots fine.
Bios already flashed to 1.51... no results.
It sounds weird to me. I have an Enermax Noisetaker II 485W PSU, the CPU is an Athlon X2 65W...
Have I got a damaged mainboard?
Thanks for support

Just tried... nothing. Lights and fans turns on for half a second, then everything dies.
I tried to remove video card too, nothing changes :(
sound like somethink is shorted. try take board of case and retry. it maybe dumb question, but are you connect 4pin cable in a right direction?(i know its can be plugged in one way only, but if you use little more force can be done...)

Windows 7 doesn't awaken with Ipod Nano 5G connected

Brand new HP computer w/Windows 7 and brand new Ipod Nano 5G. Left ipod connected to computer to charge. After computer powered down it would not restart. HP figured out that the Ipod was blocking the restart. If I unplug Ipod computer restarts fine. Anyone else finding this problem?

I had the same issue with my 5g video awhile back. The computer wouldn't boot with the ipod connected as it was recognizing it as a HD and looking for an OS to load from it.
I solved the problem by going into my BIOS and removing "boot from removable media" from the boot list. I'd give that shot, though not all BIOSs have that as a change able option independently.
-edit-
The specific computer I was having an issue on with this was an HP pavilion a1340n, but the BIOS I had installed was a custom cough*hacked*cough version I was using to install Vista and later 7.

Mac Os X doesn't booting on my macbook pro

Folks,
I've installed Windows 8.1 on my macbook pro through boot camp assistance. After installing windows 8.1, i couldn't boot my Mac OS X. I can see Mac OS X booting option in Boot Camp Control Panel on Windows.
When i select "Mac OS X" as a default boot and restated the machine. But it doesn't boot the Mac OS X and the Windows OS booting always. I tried by pressing option key while restarting/starting the machine. Only Windows OS option is there.
On Windows, i could see all the files that are in Mac OS X. Entire drive was there. Could you please help me how can i bring back Mac OS X as a booting option.

You need to reinstall OS X:
Reinstall Lion, Mountain Lion, or Mavericks without erasing 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
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 then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Lion, Mountain Lion, or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.

PC does not boot with Ipod Nano

My configuration:
Shuttle SK83G, Athlon64 3000, Windows XP Pro, Logitech DiNovo wireless desktop.
My problem:
If my Ipod Nano is connected the PC will not boot. The bios screen shows up and then nothing happens. I even can not access the bios. If I remove the ipod the PC will eventually start windows. But in absolute slow motion (I can see how the Windows startup screen fades in step by step).
If I connect my Nano after booting, everything is perfectly fine. Also with my Ipod Mini connected, the PC boots up without a problem.

it's not just a Nano problem, but a USB port problem
That's correct. USB is famous for this. Something in the BIOS (probably) is telling it to try and boot from the nano, but of course it can't find a valid OS there. And the solution is just what you suggested. Don't boot with the nano connected.

Remote on apple earphones doesn't work with iPod Touch 4G :(

Hi I have two in-ear earphones, the Apple one and the V-Moda RRMT, the one with the remote similar to Apple's. I've heard volume control works with iPhone 3GS, and have tried both earphones in iPad and they both work. Recently I bought an iPod Touch 4 and found that the volume control of Apple works while V-Moda's doesn't. Since both earphones (presumably) uses the same tech to control the volume, my current thinking is there may just be a problem with the way I'm plugging in the V-Moda earphone. I've tried reseating it several times and I still haven't been able to resolve this issue.
After scouring the google and the v-moda site, I still couldn't find any definitive confirmation that iPod Touch 4 doesn't support V-Moda's volume control. I'd like to know if V-Moda's volume control is compatible with iPod Touch 4 or not, and also the possible reasons why they don't work together.
I was looking at the earphone jack earlier and I found that regular earphone jacks only have 2 bands, while earphones that connect to iOS devices have 3 bands, so I'm guessing the 3rd band is what Apple uses for all of the extra functionalities such as Mic, Play-Pause-Talk, and Volume Control. Upon further inspection I saw that the 3rd band is not wholly covered in iPod Touch 4, could it be that the input signal coming from the V-Moda remote isn't strong enough to be received by the earphone jack of iPod touch because it doesn't fully encircle the third band? Any clarification on this problem would be greatly appreciated.

Have you tried turning your iPod off and back on? My son wasn't able to see the AirPlay icon until he did that. He has a 4G Touch and I have a 3G, but we still don't have AirPlay working correctly. It connects and disconnects randomly, but we are able to see the icon most of the time.

Refind-efi 0.8.1-1 doesn't boot with custom refind.conf

Recently upgraded to refind-efi 0.8.1-1 and manually ran refind-install.
I usually have the option ¨default_selection "bzImage,vmlinuz"¨ enabled in refind.conf but after some trial and error I found refind wont load the default boot entry with this enabled any more.
I moved
/boot/refind_linux.conf
and
/boot/efi/EFI/refind/refind.conf
and performed a ¨clean¨ refind-install.
If I select the default boot entry, with ¨default_selection "bzImage,vmlinuz"¨ enabled, refind shows the normal boot screen with standard options, but doesn't load the kernel. If I press F2 and select the boot with minimal options (in this case the same as standard options) the kernel boots instantly as expected.
If I use the standard refind.conf-file w/o ¨default_selection "bzImage,vmlinuz"¨ the default boot-entry with standard options works fine.
Anybody able to reproduce?

\hbar wrote:Strange... A rEFInd bug perhaps?
I suspect so, but would like to see it reproduced before I file a bug towards rEFInd.
\hbar wrote:When you select the arch entry, is the line that specifies the kernel and its version the same whether the default_selection is set or not?
Yep, the commandline options "ro root=UUID=836e34d6-bc33-4044-a337-372a3d240f49 quiet" plus initrd are the same in the "Booting OS"-screen, whether I select the default "Logo"-entry, or specify which options to boot with via F2.
\hbar wrote:What if you set 'default_selection arch'?
Don't think that's supported, and it doesn't work .
I've also tried "bzImage", "vmlinuz", and "vmlinuz-linux" seperately with the same result.
Should I file a bug now or wait until somebody experiences the same problem?

Computer won't start with iPod plugged in

Hey all,
Just got a brand new MacBook Pro and a 30 gig iPod. When I restart with the iPod plugged into the USB port, the computer sits at the white screen forever and doesn't boot into OS X until it is disconnected. How do I fix this? Thanks!

I don't know if this will fix the problem, but here it is:
1. start the macbook up normally w/o the iPod plugged in.
2. right after u hit the power button hold down the button combination "s" and "command"
3. do not let go until the screen goes black and white text is on it. when the text stops moving there will be a prompt.
4. type the following text WITHOUT QUOTES "fsck -f"
5. then when it is done do that same thing again.
6. then try to exit type the following text WITHOUT QUOTES "reboot"
7. then try to reboot with the iPod connected
if that does not work take it into a apple store.

Problems restarting iMac with iPod plugged in after last software update

Hi everyone,
I have an almost 2 year old 24" iMac Intel, running OS X 10.4.11 and a 30gb iPod video.
I've been having problems with restarting after the last software update. When I went to restart my computer as required for the update, it shut down, started up (the start up sound came on) and then went to just a blue screen for about 10 minutes or more. I got worried and shut down by holding the power button. Then I turned it back on and the same thing happened. So I shut down with the power button again, unplugged my iPod and external HD, turned the computer back on, and everything started up as normal. So I figured it had to do with one of those. I found that when I've started up with the external HD plugged in everything is fine, but every time I restart with my iPod plugged in, the same thing happens!
This has never happened before, and I've never had problems with my iMac before this... Can anyone help?
Thank you!

Hi, try-> System Preferences->Start Up Disk->ensure OS is highlited.
Some Macs find it difficult to Start/ReBoot when an iPhone or iPod is connected, it's as though the computer is searching to boot from an external HD. I would Repair Permissions & do the SMC reset.
Leave the iPod/iPhone unplugged @ reboot...L
