Grey circle with cross in the middle when trying to boot from Tiger DVD

When I try to boot from the DVD that installs Tiger, it get the Apple logo and spinning wheel as usual when booting a Mac OS. Then the Apple logo turns into a grey circle with a cross in the middle, signifying "no"! I haven't locked my firmware, but could it be locked? I got the computer from Apple when my original G5 died (it was a lemon). Did Apple lock the firmware???
The OS on my Macintosh HD is Leopard.

So what specific model is this iMac? Is it a G5? Or is it an Intel iMac?
If it is a G5 you have posted in the wrong forum, this is the Intel forum. A G5 is not an Intel Mac, it has the IBM PowerPC CPU.
If this is an Intel, which Intel model is it? Did it come with Mac OS X Tiger installed on it? If it did not come with Tiger, if it came with Leopard, you cannot put Tiger on it.

I have an ibook g4 that boots to blue screen and hangs. Safe mode will boot but hangs after log in. I have reset PRAM, NVRAM, and the PMU. Booted from Diskwarrior and rebuilt and tested the HD, working properly. Boot from Tiger dvd shows images? no text

The tiger install dvd boots only to show an image of what looks to be two steps, not sure what its showing me.. possibly inserting RAM? Anyone have any ideas? Thanks in advance.

Could you get a picture of the screen, load that into your working computer,
and post it into a reply here? There are a few kinds of situations where a
similiar display of that sort may appear.
Given the G4 iBook PPC (which model) is a bit dated now, one has to
assume you have the original 'install-restore' DVD it came with, new.
What was or wasn't it doing, before you chose to try to boot Tiger DVD?
Do you have a second Mac, one w/ FireWire ports; maybe Thunderbolt?
It may be possible to further look into the ailing iBook G4 via FireWire
from a second Mac, and attempt to investigate, or save old data to some
external drive, USB Flash; in case you need to totally wipe the HDD.
An image of the iBook screen may be helpful. Someone else with recent
troubleshooting or extensive use of iBook portables (or other OS X issue)
that presents such a screen instead of a normal progress screen, may
have an immediate idea. Without an image, I am not venturing a guess.
What key did you hold down while trying to boot the computer from DVD?
One set of keys can get you a Startup Manager. Among other options.

Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. 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 click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
The main difference if you are using Lion or Mountain Lion is that you must first boot from the Recovery HD. Simply boot from the Recovery HD to perform the above.

TS3680 My 2008 iMac sounds the chime, shows the Apple logo on a grey screen, then shows a grey circle with a line through it an doesn't boot. Don't know what to do next.

My iMac won't boot. I have tried putting my DiskWarrior DVD in and starting the computer holding the "c" key down wihile it is powering up. The DVD started to make encouraging sounds like it was trying to boot from it. Then a grey circle comes on the screen and there is a sound of the DVD attempting to read and failing. Now the DVD is stuck in my computer and I can't get it out.
Any suggestions as to what to do next?

My Macbook has a Kernel Panic when trying to boot from Mac OS Install DVD

It might also be relevant that my Accounts Preference Panel crashes System Preferences when I try to open it. Disk Utility sees no problems with my drive, and booting into single user mode and doing a disk check has no results.
I am running a 2010 Macbook

2.4 Duel Core Processor
Mac OS 10.6.8
Windows Installed Via Bootcamp, but problems occured before Windows was installed as well.
Anything Else that I need to add?

Try reinstalling Snow Leopard. If you continue getting a kernel panic booting from the DVD, then either you have a bad installer disc or you have a hardware failure.

External Hard Drive Not recognized when trying to boot from it.

So I am trying to boot from my external hard drive through firewire but my computer doesn't seem to recognize the external. There is some problem with my Macbook not booting up correctly and I want to backup my data before reinstalling Tiger. They did this at the Apple store and ran disk utility on it my Macbooks hard drive. I could access all my data, but now when I get home and plug in my hard drive, hold down option after booting, the only drive that pops up is the Mac HD. I read somewhere to try partitioning the external drive as Mac Journaled and I did so with my working Macbook Pro. Any ideas whats going on?

Well i got most of my information off the old one, now I am trying to reinstall Tiger to the MacBook. Problem is I initially tried to do an archive install and the install kept failing after the second disc when it asked for the second install disc.
The people at the Apple store suggested that I try to do a wipe of the hard drive and install. Now when I put in the Disc 1 install disc and boot from the cd drive it just sits for a while and then ejects disc 1 and goes back to the place where the install failed from before ie: it keeps asking for the second install disc.
I can't figure out a way to get around this and just do a clean install on the machine. Any thoughts would be great.

"Missing Operating System" when trying to boot from USB

I have a macbook air (3,2), and I'm trying to install Arch onto the partition that currently has Ubuntu. I have tried a few different ways to get the Arch core iso onto the usb key drive, but no matter what I do, I am ending up with the message "Missing Operating System" when I boot into it.
I started out using the instructions from https://wiki.archlinux.org/index.php/US … tion_Media for writing it on OSX, using diskutil unMount, then the dd with bs=8192, and of=/dev/disk2
When that didn't work, I tried booting into my ubuntu install, and used just a plain
sudo dd if=archlinux.iso of=/dev/sdb
Still no luck, so then I went to my old standby of unetbootin, which didn't do any better. I just tried yet again with the dd in ubuntu, and I'm still not having any luck.
Here's some of the relevant info I could find:
$ sudo dd if=Downloads/archlinux-2011.08.19-core-x86_64.iso of=/dev/sdb

One interesting thing I noticed was that the dd took about 10 minutes in mac osx, and under 2 seconds in linux. That seemed like a pretty big difference between the two systems, but I'm not sure if that's related to the batch size on the write, or to the implementation of dd used in OSX.
Is there something obvious I'm missing? I know the computer is able to boot from this key drive because I was able to boot an Ubuntu livecd from it just a few days ago. Unfortunately, the MBA won't boot from my external cd/dvd drive because it's not the apple brand super-drive, and I don't want to spend the money for a super-drive, so a cd-based install isn't an option.
Really looking forward to playing with Arch, because some of my friends recommended it to me highly. I'm a former gentooer (years ago) who became fed-up with installing *everything* from source. I can't stand ubuntu doing everything for me, and debian always seemed so far behind the curve on everything, so Arch seems like the perfect OS if I can just get into the installer. :)
Thanks so much!
~Maquis

Oh, forgot to mention, I did the dd from ubuntu with both bs=4M and without a bs argument. the version without the bs argument is the one that went really fast.
Neither version would boot, so I don't think that the way I'm writing it is the problem.
I did just notice that if I just do a sudo fdisk -l without specifying the drive, I have 2 entries for my drive:

Iphone not being recognized by Itunes so I cannot fix the songs with the red circles with squares in the middle

I have an Iphone 4s and i have two reocurring problems. So my first problem was after I had synced all my music most of the new songs and some old that never had a problem before had a red circle with a red square inside of it. I've gotten rid of it before but I dont even know how. I've read countless discussions and tried so many things that I dont even know what works. i figured it just fixed in time but there has to be an easier way that isnt so frustrating and annoying. So now my iphone isnt even being recognized. the apple mobile device is installed and running and has been stopped, started and restarted plenty of time. ive reset and restarted, reinstalled everything. my phone is charging, it just isnt being recognized by itunes or my pc. also in the device manager it isnt showing up. I am getting very close to smashing my iphone and switching to an android. everything is up to date and i also have tried to sync music on the first ipod touch that came out and even that isnt being recognized. I just want to get rid of the **** red circles and connect my iphone so i can sync it a million times in hopes that the red circles will just disappear. does anyone know why these red circles appear? Apple needs to get their stuff together and give us actual directions on how to fix this!!!! thank you for your help!!!

I had this problem too and my roommate solved it!
Go to 'Settings'
'Music'
Scroll to the bottom and enter your password to log onto your home sharing
Then connect to iTunes and sync!

Startup- Grey Square with ? in the middle

Whenever I boot it up I get the white screen then the grey square with the ? sign in it for 2 or 3 secs then the apple and it boots up. I think this is because I had boot camp on here then told it to repartition as one partition again. So im thinking its looking for that windows partition at startup then just bypassing and booting into OS X. Any way to get rid of it?

Have ya looked at your Applications > System Preferences > System > Startup Disk, and clicked on the Mac OSX icon on the local disk, or partition disk?
Then restart and see if it goes straight to your local system ... I'm thinking your MBP is looking for a network boot because that is what it is being told.
Or have you already checked that setting?
So, you had BootCamp in a separate partition, which no longer exists? Don't go there, much ... why did you cancel that setup? Is there an "uninstall" that did not get completed properly, or did you have to just hard-flush the 2nd artition?

I get a red circle with a slash through it when trying to move music into folders.

I had to reformat my laptop hard drive. I moved everything to an external hard drive, and then brought it back after the reformat. I did something wrong, so all the folders are gone. I can create new playlist folders now, but when I try to move the music over, as soon as I get in the area with the playlist folders, it gives me the red circle with the slash through it, and stops me form dropping the songs in the folders.
I am logged into my account and the computer is authorized to my iTunes. Not sure where to go from here, other than the Apple store.

iTunes doesn't pay much attention to file and folder names with one minor exception. On import any untagged files will be given their filename as their track name.
You can drag a folder full of files onto a playlist and all the tracks will be added to the playlist, having first been added to the library if iTunes isn't already aware of them.
When you add files to iTunes from outside the iTunes Media folder and the option Copy files to iTunes Media folder when adding to library is enabled then copies will be created, and iTunes connected to those. If you subsequently import the same folder you will create duplicate files. If your files start life inside the iTunes Media folder, or that option is disabled, then they can be imported again without creating duplicates. However, if your files start life inside the iTunes Media folder and the option Keep iTunes Media folder organised is enabled, then once you have added the folder to the library the files inside it will probably be rearranged.
In the long term your library will be easier to maintain if all the files are inside the iTunes Media folder. It is probably easier to let iTunes manage them unless you are really particular about the layout or are importing files without tags such as wav, in which case I have some scripts that can extract useful information about the file from the filename and path provided iTunes doesn't get to throw it away first.
If your main aim is to rebuild some existing playlists, which exist by dint of all the files for each playlist being in separate folders, and you want to avoid creating duplicates, then try this.
Create a new empty playlist, select the music folder and put it into date added order.
Move all the files into the Automatically add to iTunes folder.
Select all the recently imported files, drag and drop them onto the new playlist.
Repeat until all files are added

I purchased an unclaimed luggage at the airport that had a mid 2010 13" MB-Pro -- It comes up to a boot screen with snow leopard or Windows -- I tried to boot from Optical with Lion install -- it woon't won't boot from the optical drive, help

It won't go to taget disk mode -- I took the drive out and used disk utility to re-partition and format - now I get the folder with a question mark and it still won't boot from optical or usb or go to target disk mode -- I haven't tried installing lion on the disk while it is out and then putting it back in the machine --
according to the serial number, it is still under apple care but since I don't know the person that used to own it I can't get it transferred to me -- or will apple do that since I bought it in an auction?

Ok so I've done what you said and this is what it's come back ....
I don't know that these are the errors , but they're the things which don't look right ...
Throughout the shut down there is a recurring line ;
It says ;
Com.apple.launchd 1 0x100600e70.anonymous.unmount 301 PID still valid
Then there are 2 more which I think are related ;
Com.apple.securityd 29 PID job has I overstayed its welcome , forcing removal.
Then the same with fseventd 48 and diskarbitrationd 13
Oh and on Launchd1 : System : stray anonymous job at shut down : PID 301 PPID13 PGID 13 unmount...
Then the last process says "about to call: reboot (RB_AUTOBOOT).
Continuing...
And stops ...
Hope this means something to you ... Thanks again for your help so far :-)

Why do I get the message "The installer requires admin priviledges to run" when trying to install from a DVD?

I am trying to install software from a DVD on my Mac Mini, When I click on the installer I get the message "The installer requires admin priviledges to run." I have admin priviledges when I look at the account info in Sytem Preferences. ANyone have an idea what to do about this?

It's a defective installer. If it needs elevated privileges to run, it should prompt for an administrator password. Since the installer is defective, you can assume that whatever it installs -- or would install, if it worked -- is also defective.

IMac shuts down when trying to upgrade from Tiger to Leopard

My iMac, purchased in November of '07, came installed with Tiger but also came with a Leopard OS update disk. When trying to upgrade to Leopard last week, every time I rebooted off the disk the computer would run for a minute in the gray screen and then suddenly shut off with no warning message. I checked HD in disk utilities, repaired my permissions and tried again with the same results. I've got 30 gigs of free space and 4 gigs of RAM which should be plenty. I talked to Apple support who walked me through the installation procedure with the same results and ended up shipping me a new install disk which came today. I am getting the same shut down on reboot with their replacement disk. Apple actually sent me two white disks. The first is labeled "For Mac Computers, Mac OSX Install disc 1" The second is labeled "MacBook, Mac OSX Install Disc 2" Since the second disc is label "MacBook" is it possible they sent me the wrong set of discs?
Thanks

rk87,
Thanks for replying. I have a 500 gig hard drive which yields a 465gig usable capacity, so, at 30 Gigs available, I don't have 10% of the drive free. This may be an issue, but my more immediate problem is that I can't get the install disk to boot up at all.
I called apple support again see what I could find out about the install disks which wouldn't work. The support guy seemed like he had a lot of knowledge about the system and suggested trying the Tiger install disk (that came with the machine) to see if it would boot up, which it did. After that success, I tried the Leopard update disk in another iMac I have at home and it worked as it should. Since the disk worked fine on the other mac, the guy at tech support speculated that there is some sort of hardware issue causing the install shut down on the computer in question.
His speculation was about the memory installed in the machine which might be the issue. I had bought the computer from an Apple Authorized store here in town who upgraded the RAM to 4GIGs using third-party memory. Even though the memory seems to have functioned properly for the past year, apple support says that there could be some sort of incompatibility with the third party product causing the install disk not to work.
Apple support told me about running a memory diagnostic off of the Tiger install disk by rebooting with the disk in the computer and hold down the "D" key. After I got off the phone I ran the test which turned out to take an hour in its long version. The test indicated no problems, but apple had told me that it might not be totally conclusive. At this point, I'm taking the computer back to the store where I bought it and will let them figure it out.
