ITunes causing prohibitory sign?

yesterday I was using an applescript to take music off of my friends iPod, when my computer started slowing down, songs that i was playing were pausing at different times, and the script wouldnt take all songs that I told it to. So i figured that my computer was just doing too much at once so I turned the computer off. When I turned it back on the apple logo at the begining of the start up was sitting there with the progress circle spinning, and then the apple logo changed into a prohibitory sign. After reading around on the forums, i tried to using the reset-nvram, reset-all in theopen framware but nothing happened. So i looked around some more and i found the "control-S" command, not knowing what it did, i thought i would give it a shot, so I hit it during start up and i got a black screen with white text with lots of words, and numbers that didn't mean anything to me, but one thing did jump out at me and that was "com.apple.driver.iTunesphonedrive has no kernel dependency" I was wondering if iTunes could be the cause of my problem, if so, how do i get my computer to start up? Thanks.

The flashing question mark means that Firmware has been unable to find a startup volume. It searches around and evidently finally found something. By the old OS logo, I take it that you mean OS 9. But, it sounds like it is not finding OS X.
This begins to sound like some problem related to the disk or filesystem. I suggest that you boot off your install CD and use Disk Utility to repair the disk. The are instructions at Resolving Disk, Permission, and Cache Corruption. See the section on repair disk.

My Mac OS Lion 10.7 FileVaulted HD does not boot, prohibitory sign, stop sign appears some minutes after boot starts. Disk Utility repair shows four error messages:
Unable to bootstrap transaction group 2517: inconsistent crosscheck
No valid commit checkpoint found
The volume xxxxxxxxxxxxxx(here it shows physical volume number) was found corrupt and can not be repaired.
Problems were encountered during repair of the partition map

I suppose it is serious bug in Mac OS Lion managing FileVault and wonder what the help could be?

Most likely culprit is your Lacie drives which are notorious for flaky power supplies which cause just the sort of erratic behaviour that you describe. Have had similar issues myself. Lacie has been good about replacing my power converter-- twice. If you have seven of them, good luck finding the bad one or more. Like I said, the behaviour is erratic. Sometimes it'll work sometimes not. I can't comment on Samsung drives because I've never used them and have never heard anything about them. Same with Softraid. Why not just use Disk Utility. Sounds like you're ready for an external hardware raid. This will be much faster, much more reliable, and may even be cheaper than seven firewire drives. Check out G Tech, and Maxx Digital for starters.
Best of luck

Macbook 2010 won't boot - flashing question mark, prohibitory sign then Apple icon

Okay so some of this is my fault. We'll get to that later.
A few months back this Macbook my uncle gave me (without the Mac OS X Installer DVDs it came with) failed to boot - displaying the spinning gear/Apple icon/grey screen so many others have experienced.
I've done everything that could be done without the Installer DVDs - reset the PRAM, the SMC, attempt to go into Safe Mode (failed - only displays the progress bar until it fills up then back to the grey screen)
I've also done fsck -fy and it would always return to either "FILE SYSTEM WAS MODIFIED" so I'd run it again to receive the result "The volume Impala appears to be okay", but whenever I would hit "reboot" it's like nothing ever happened.
I got a hold of a(n illegal) copy of someone else's Installer DVDs from the net - not so I could install that but so I could load DiskUtitlity from a bootable flash drive to transfer files to my external HD by the restore option in DiskUtility - worked for a bit (ran verify permissions, repair disk permissions, the whole shebang) but then failed, was only able to copy the "Applications" folder by restoring the volume to the external HD I had plugged in, and nothing else.
So when just this afternoon, I was fiddling with the prompt that displayed whenever you entered single-user mode, trying to move documents from inside the Documents folder into the Applications folder (because I thought that if I did "restore" all over again it would copy needed files into my HD like it did the last time - the /Volumes directory disappeared.
What could have caused this? I know that this is what's causing the flashing, alternating icons during attempted startup, but I swear that I didn't even think of doing anything to modify the /Volumes directory. One minute I was entering files /Volumes just to fiddle with it, then proceeded to go in deeper to cp or mv files into the /Applications directory, the next it was gone.
What should I do? I contacted the local Power Mac Center nearby to check if they're carrying the Mac OS X Snow Leopard Installer DVDs but I'm pretty sure that those things are limited now to the U.S. and the U.K.?
Please send help/advice, I'm broke and pretty much very very desperate.
Thank you for your time.

and also we have this older MacBook (2007 I think) that flashes the prohibitory sign (circle with slash going through it) whenever I try to boot it - started doing that a few days ago and I swear on both laptops that there are no peripherals that are plugged in except for the MagSafe (this older MacBook has no batteries installed since the last one shot out two years ago and we haven't had the money to replace it..)
Could the MagSafe be the problem? Because I haven't been doing anything dangerous on this older one (even cleared out some old files/videos to free up disk space) but still, it went ahead and got into a coma.
I can only access it via Safe Boot (pressing shift right after I power it up) and thankfully, its FireWire port using Target Disk Mode.
How I wish I could use Target Disk Mode on the later (2010) model, but alas, the only solution is to purchase the Installer DVD - only the Apple Reseller I contacted hasn't contacted me back yet.

MacBook doesnt boot. It shows Apple logo and spinning wheel. Soon it wont go beyond prohibitory sign with spinning wheel

I have a MacBook (Late 2008 edition) having Mac OS X 10.6.8 SnowLeopard OS installed (2 X 512GB RAM, 160 HDD). I copied some mp3 into iTunes library and soon the process got stucked. MacBook was not accepting any command/it seemed to got hanged. Carelessly, I switched the MacBook OFF by pressing the Power button. Now, when it began to boot again, all I hear was some clicking sound from the MacBook (seems HardDrive failure because the sounds seems to be from HardDrive). After few seconds, It showed flashing folder with question mark and it wont go beyond that.
Steps I tried:
1. Resetting NVRAM, PVRAM and SMC.
2. Booting in safe mode.
3. To boot from install DVD (Mac OS X 10.6.3 SnowLeopard).
4. Holding down 'option' button while booting. It shows the "Mac OS X Install DVD" icon but as I click it and press return, it again shows Apple logo with spinning wheel and little later it shows prohibitory sign with spinning wheel. This will now remain for ever and ever.
5. I bought a new 500 GB HardDrive and replaced the old one with this. Now trying to boot with DVD (Mac OS X 10.6.3 SnowLeopard) it again hows Apple logo with spinning wheel and little later it shows prohibitory sign with spinning wheel. This will remain for ever.
Any suggestions to overcome this problem will be highly appreciated and I'll be very grateful for all your help.
Thanking You.

Hi julenawang,
Welcome to Apple Support Communities.
It sounds like your MacBook has a startup issue and you aren't able to reinstall Mac OS X on a new hard disk. The article linked below has a lot of great information and suggestions that will resolve most issues like the one you described.

Prohibitory Sign on Mac OS 10.3.9 installed onto an iMac 350MHz

Hi.
Mi name is Jose Blanco.
I have an iMac 350MHz which has the Mac OS 10.3.9.
Six mounths ago I installled a new hard drive into this computer and I installed a fresh Mac OS 10.3 onto it.
Yesterday (august, 9) this computer showed the prohibitory sign, consequently I've installed the operating system again and the computer has worked fine until today, that it showed the same issue.
Thanks for everything.
Jose Blanco

Hola Jose!
What size is the Hard Drive, and how much space is available?
How much RAM is installed, and is it original or added?
Have you run Repair Disk?
THESE ARE THE STEPS FOR USING DISK UTILITY TO REPAIR YOUR HD
1.Insert your Mac OS X CD-ROM disc or Restore DVD disc, then restart the computer while holding the C key.
2.Once started up from CD or DVD, choose Disk Utility from the Installer 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, then re-run Repair Disk until no errors are reported.
7.When finished, select Quit Disk Utility from the Installer menu.
8.Select Quit Installer from the Installer menu.
9.In the resulting pop-up window, choose restart.
10.After the computer has restarted, you can eject the CD.
Have you run Repair Permissions?
TO REPAIR PERMISSIONS ON THE STARTUP DISK
1.Open Disk Utility, located in Applications/Utilities, and select the startup disk in the left column.
2.Click First Aid.
3.Click Verify Disk Permissions to test permissions or Repair Disk Permissions to test and repair permissions. (I never "Verify". Just run "Repair".)
Rerun RP until the only message it reports is:
"We are using special permissions for the file or directory ./System/Library/Filesystems/cd9660.fs/cd9660.util.
New permissions are 33261"
This is a status message and not a cause for concern. You may safely ignore it.
Or these:
"We are using a special uid for the file or directory ./private/var/at/jobs. New uid is 1"
"We are using a special uid for the file or directory ./private/var/at/spool. New uid is 1"
Again, these are status messages, which appeared after Security Update 2005-001.
There may be others that you can ignore. Complete list at link below.
Spurious Permissions Errors Using:
Panther 10.3.x
When "Repair Permissions" is complete. Quit "Disk Utility".
If neither of those corrects it, Reset The PRAM & NVRAM.
How To
1.Shut down the computer.
2.Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3.Turn on the computer.
4.Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5.Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6.Release the keys.
Good Luck!

Prohibitory sign after repairing privileges from CD

Snow leopard was working. I installed the upgrade on an imac 20 inches.
I started from the CD to verify disk and repair privileges.
When I repaired privileges, one file was bad, i think something related to "core"
I restarted and.... have a prohibitory sign! Imposible to enter the system.
I succeed in entering again my system reinstalling the upgrade of snow leopard
How could it be? What's wrong with my system? Do I have to format the disk and reinstall everything from zero? I'm scared this problm could happen again...
Message was edited by: catburlow

You removed everything from your hardware profile sig that, erroneous I'm sure, said you had a G5, which can't run 10.6.
from the CD to verify disk and repair privileges.
The SL DVD 'ought' to be okay to REPAIR the hard drive, and repair permissions (though ideal is to repair from a 2nd hard drive, such as the one you made with CCC).
Leopard definitely saw changes and doing any type of repair work should be done from the SAME OS version as you are running and not from older versions such as on DVD.
The article on kernel panics recommends some steps, such as clearing NVRAM for when you get a prohibitory sign. And to look at and disconnect everything possible as well - USB and FW devices/cables have been known to cause panics.
Why not repair permissions while booted? won't Disk Utility run, even in SAFE MODE when booted from your clean fresh install? though really shouldn't need to.
As for power failure, I would never run a computer without a UPS (uninterruptable power supply) ....

IMac crashes to black screen with white prohibitory sign!

My iMac (late 2013) i5 version keeps crashing about once a day. Every time I come home from work, the screen is black with a white prohibitory sign displayed. I'm unable to do anything and have to hold the power button down to restart it. It seems to work fine after a restart, but randomly crashes to this same screen. I've never actually seen it crash because it only happens when I'm not using the iMac. It seems like it might be something with power management or screen saver. Unfortunately, I can't seem to narrow it down as I've tried to change all the settings and it still happens. I really don't want to do a complete re-install of Yosemite, but it seems like that's the only thing left to try. Can someone please help?

I just changed my residence to the US and now I cant register my new US credit card on itunes cause the state list doesnt match to the US states, what should I do?

I just changed my residence to the US and now I cant register my new US credit card on itunes cause the state list doesnt match to the US states, what should I do?

Your credit card info, billing address must be the same country as the iTunes store country you registering.
For example, you can’t have a credit card from a U.S. bank with a U.S. billing address registered in the iTunes store for China.
I tried to change my payment information too, but it happened the same, I can change the information but when I get to the state part, it only shows the other country states
Remove all payment info and save it.
Then change the iTunes store country to U.S., add a U.S. credit card with a U.S. billing address.
As previously suggested, if this does not work, contact iTunes store support.

Power Mac G5 Showing Prohibitory Sign on Start Up?

Earlier this week my Power Mac G5 1.8 ghz dual started to show a prohibitory sign on start up. The hard drive was original to the machine (from 2004) and I wanted to upgrade it to a larger size anyhow, so I put in a new hard drive thinking that might solve the problem and give me an upgrade at the same time.
After I installed the new hard drive, I formatted it and did a restore from Time Machine of my system. When I restarted, I got the prohibitory sign again. I restarted holding down the option key to see if it found the new drive and it did. So I selected the new drive and it started up from the new drive with my restored system on it with no problem. Then I went to system preferences and made sure the new hard drive was selected as my start up disk. On restart, I got the prohibitory sign again.
Then the weirdness started. On subsequent restarts, I get the prohibitory sign intermitently whether I'm starting from the hard drive, my Leopard installation DVD, my Disk Warrior boot disk, or my old Panther installation disk. It seems to boot without any problem from the Apple Hardware test CD. I've run the extended apple hardware test and it didn't find any problems. Most of the time, I get a prohibitory sign no matter how I'm trying to boot up, but sometimes it will boot from the Leopard installation disk or the hard drive, but when it does, it freezes after running for a few minutes. I've tried swapping out the memory sticks and it's made no difference.
Is it possible this is a software problem and not a problem with the motherboard or other hardware? I sure hope so, because I love this machine. Anyone have any suggestions about what I might try next? I've read about the "hair dryer" solution, but if Apple Hardware Test didn't find any probemms with the memory or motherboard, could that still be a solution?
Thanks for any help or suggestions.

Thanks, japamac. Yep, I should have said I replaced the old hard drive with the new one. So, it now only has the one, new fresh hard drive. The new drive is a WD Caviar Blue 320gb.
I set the jumpers on the new drive for 5-6 to slow the new drive down to 1.5. I've also tried resetting the PRAM several times, and tried restarting in safe mode. Every few tries I can get it to boot from the hard drive or a boot DVD/CD (maybe once every 10 tries), but it freezes up after running for about 10 minutes. The only instance this doesn't happen is if I boot with the Apple Hardware Test CD. It didn't freeze up during the 2 hours it took to run the extended test.
Thanks for trying to help me.

I had to reinstall iTunes cause during update it was shut off by mistake, now it won't come up and says,"The file "iTunes Library .itl" cannot be read because it was created by a newer version of iTunes", what do I do?

Empty/corrupt library after upgrade/crash
Hopefully it's not been too long since you last upgraded iTunes, in fact if you get an empty/incomplete library immediately after upgrading then with the following steps you shouldn't lose a thing or need to do any further housekeeping. In the Previous iTunes Libraries folder should be a number of dated iTunes Library files. Take the most recent of these and copy it into the iTunes folder. Rename iTunes Library.itl as iTunes Library (Corrupt).itl and then rename the restored file as iTunes Library.itl. Start iTunes. Should all be good, bar any recent additions to or deletions from your library.
See iTunes Folder Watch for a tool to catch up with any changes since the backup file was created.
When you get it all working make a backup!

Prohibitory Sign in Pages document

Hello~ I created a table in Pages and somehow a gray prohibitory sign appeared in the table, on each page. I am unable to make any changes to the document now. Please help!

Kim,
I know that you said you created the table in Pages. Can you describe the table for us and characterize the document that it is in?

"you must first sign in to iTunes Connect and sign the relevant contracts": how?

I'm trying to get my iBook (made in iBooks Author) up on the iTunes store and am stuck.
I now have an iTunes Connect account into which I can sign in. When I try to use iTunes producer, and enter my login info (which works on the browser), it tells me
"There is a problem with your login information. To use this application, you must first sign in to iTunes Connect and sign the relevant contracts."
I'm not sure what a "relevant contract" would be. I look at "Contracts, Tax, and Banking" at iTunes Connect, and there is one entry with Contract Type "Book". However, I can't request it (that is grayed out), and the "Legal Entity" pull down does not show me (as found in the "Manage Users"), but only shows "select".
I therefore can't seem to find a way to do anything to allow me to login with my book via Producer to get it "produced."
Does anyone know what is going on?
The FAQ is a blank page, the "Contact us with questions" asks you to pull down a topic and has no topics there! Very clumsy path to publishing (comparing to CreateSpace, for example). After the ease of iBooks Author it's like hitting a brick wall at 100 mph.

OK, I saw the link for the help video at the bottom - it helped. I have to add a new entity. I was fooled thinking I would already be there and that the entry was me, but it is apparently a general placeholder into which numerous entities can go. For me this was not obvious at all, and I only figured that out by watching the video (which was not easy to spot!).
I'll go through the process now and hopefully no more confusions.

Mostly because you are not using any capital letters or paragraph returns and your post is difficult to read.
