Vertical Lines Started Appearing on my 17" Intel iMac and won't go away.

My iMac has started to show bright vertical lines on the display. I've searched the forum and then the web and it looks like I'm not alone. There are thousands with this same problem on the same model iMac. Unfortunately, it looks like I didn't buy AppleCare for this computer, so I'm outta luck on a fix.
This *****, this computer is only a little over 2 years old and it's asleep most of the time!

The first vertical line (in blue) on my iMac started last week. Today another one this time in yellow. Attached monitors are fine.
There are so many postings on this, you would think Apple would have a support document on this, but the only one referred to is on dead/stuck pixels which is related, but quite different.
I leave my iMac asleep most of the time (never power off). I'm wondering if there is any relationship between this problem and supplied power?

Green emblem has appeared on the lower left desktop and won't go away.

a few days ago, a small green emblem that looks like a D followed by a reversed C with an X through it has appeared on my desktop in the lower left corner and won't go away. it is on top of everything else on the desktop and is the first thing to appear on startup and the last thing to go on shutdown.
it is there even during the startup screen when the apple appears.
does anyone know what this is and how to correct whatever is occuring in my G4 running OSX.3.9?? thanks.
G4 Quicksilver AGP Graphics 500 Mac OS X (10.3.9)

what do you know. i thought to myself, what would be the simplest solution here that we may be missing. and i tried another monitor. emblem gone.
i guess my old sony VGA monitor has an issue that it is trying to tell me about. in any event, we're good for now. that is a relief.
thanks so much for working with me on this.
With the emblem displaying, hold down the Shift,
Command, and 4 keys simultaneously and take a
screenshot of that area of the screen; if it shows
up, it is present in the computer's offscreen buffer,
and is therefore caused by software. If not, it may
be generated by a process which is drawing directly
to the screen, or it is a hardware issue. Since it
appears at the screen with the Apple logo, it isn't
running under your account, as the contents of your
home folder aren't even consulted until the progress
bar which appears later disappears. It cannot be one
of the Startup Items that may have been set up in the
Accounts pane of System Preferences.
Anything which would make a change at the Apple
screen would need to be running as root; most often,
this would require that you type in your
administrator password, but there are other ways of
having a process run as root.
In addition, restart your computer from a Mac OS X
installation CD and see whether or not the emblem
appears; this may help determine where it is coming
from.

IMac 10.4.11 Because permanent vertical lines have appeared on my screen, I need to get a new monitor. The adapter apple sells goes from female VGA to mini-DVI. What kind of cable should I get as well:female to male?

If I use an adapter (female VGA to mini-DVI) for my iMac 10.4.11 OSX, I also need a cable. Should that cable be female VGA to male VGA?
Permanent vertical lines have appeared on my display, and connecting to another display (monitor) requires a cable and adapter. I want to be sure I am purchasing the correct cable for the Apple adapter.

What made me think I need to format if I upgrade the OS?
I just presumed so really.
What made me think I need to constantly format computer with my problem?
Well, after many attempts to repair the drive, which fails, cannot even reach the log in screen, I am left with no other choice?
And also, I have to note now, System Preferences keeps crashing without reason, it either takes ages to load, just by clicking it to open, or clicking something within it, or it just crashes.
And temporarily, it freezes the computer totally, with no response.
Seriously, am I missing a system file or something? Anyone experienced this problem before?
My computer is literally a blank computer right now, installed VLC and Shades, updated Adobe Flash Player, installed Skype and Adium. I would say Growl from Adium caused it, but it has happened prior to Skype and Adium. Any ideas anyone?
Thanks,
From Lelouch

I have a red vertical line on the right side of my screen and it will not go away tried restarting my computer and that didn't help at all, please help me with this problem it is kind of annoying

I have a red vertical line on the right side of my screen and it will not go away tried restarting my computer and that didn't help at all, please help me with this problem it is kind of annoying

If it's a thin 1 pixel wide vertical line it's highly likely it could be caused by a defective LCD.
One quick basic way to check is to note the position of the line. Then go to System Preferences, Displays, and lower the resolution. If ther line moves it's on the video and the logic board or video card if fitted is likely to be defective. If the line stays in the same position it's likely to be an LCD fault. Either way to have it repaired you'll need to visit an Apple store or AASP.
The worst offender for this problem is the Late 2006 17" iMac. FOC replacement of the LCD used to be covered by a quality program, but it's now ended.

Help! Random blue screen appears and won't go away also getting glitches.

Hello,
So recently a blue screen has been randomly appearing taking up the whole screen, it won't go away until I hold down the button that turns laptop off. My screen has also been glitching and just now a glitch took up the whole screen then my background dissappeared to be left with this blue screen. Please help, I can't afford a new laptop!

That is odd and I'm not savvy enough to tell you what it means. But I'd venture a guess that you're in some kind of a debug mode. Again, a wild guess, but perhaps if you created a new admin account and log in with that, maybe the more (if that's the issue) will go away?
I'd start up in safe boot mode first and see if that helps. Maybe it's something running in your startup items?
Have you Googled the phrase? You might find something on a more technical Mac site that way? I just Googled <<event sysontoc>> and came up with a few leads you might want to check out.

I am on a intel Imac and need to update to 10.5. How can i do this?

I am on a intel Imac and need to update to 10.5. How can i do this?

You really should update to Snow Leopard because Leopard is no longer in production. The following tells you about Snow Leopard but also what's need to upgrade past Snow Leopard should you be able and wish to do so.
Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s MobileMe service; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion - System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer)
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer)
         3. MacBook Pro (Mid/Late 2007 or newer)
         4. MacBook Air (Late 2008 or newer)
         5. Mac mini (Early 2009 or newer)
         6. Mac Pro (Early 2008 or newer)
         7. Xserve (Early 2009)
     Are my applications compatible?
         See App Compatibility Table - RoaringApps.
     Am I eligible for the free upgrade?
         See Apple - Free OS X Mountain Lion upgrade Program.
     For a complete How-To introduction from Apple see Upgrade to OS X Mountain Lion.
How to Install OS X Updates Successfully
A. Repair the Hard Drive and Permissions:
Boot from your current OS X Installer disc. After the installer loads select your language and click on the Continue button. Then 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. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) 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.
B. Make a Bootable Backup Using Restore Option of Disk Utility:
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Check the box labeled Erase destination.
5. Select the destination volume from the left side list and drag it to the
      Destination entry field.
6. Select the source volume from the left side list and drag it to the
      Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal
startup drive.
C. Important: Please read before installing:
1. If you have a FireWire hard drive connected, disconnect it before installing the update
      unless you will boot from this drive and install the update on it. Reconnect it and turn
      it back on after installation is complete and you've restarted.
2. You may experience unexpected results if you have installed third-party system
       software modifications, or if you have modified the operating system through
       other means. (This does not apply to normal application software installation.)
3. The installation process should not be interrupted. If a power outage or other
      interruption occurs during installation, use the standalone installer (see below)
      from Apple Downloads to update. While the installation is in progress do not use
      the computer.
D. To upgrade:
Purchase the Snow Leopard Retail DVD.
Boot From The OS X Installer Disc:
      1. Insert OS X Installer Disc into the optical drive.
      2. Restart the computer.
      3. Immediately after the chime press and hold down the "C" key.
      4. Release the key when the spinning gear below the dark gray Apple
          logo appears.
      5. Wait for installer to finish loading.
      6. Follow instructions.
E. If updating:
1. Download and install update(s)
2. Use Software Update, or
3. Download standalone updater(s).

I don't understand why recently with the new "pages" my computer stops responding. When I go to fix some grammar all of a sudden the little colored circle begins to appear and won't go away I restart my computer.

If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console 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 Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time after you had the problem. Select the messages logged before the boot, while the system was unresponsive or was failing to shut down. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V). Please include the BOOT_TIME message at the end of the log extract.
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post any other kind of report — it will be very long and not helpful.

Intel iMac and Adobe CS2

Greetings!
I recently purchased Adobe CS2 as well as Macromedia stuido 8. I was planning to upgrade to a new 20" intel iMac and I am curious about the performance of these products under rosetta. Anyone suggestions or additional info? Thanks
-Sam

I've been using a 20" Intel 2 GHz iMac with 1 GB RAM now for just over a month and use Adobe CS2 on it and I'm incredibly disappointed with the performance of the software under Rosetta. So much so that I regret buying the Intel version and wish I'd bought a good old G5 processor model.
The main issue is speed. I upgraded from a Dual 866 mHz G4 and am encountering slower performance with CS2 on my new iMac than I did on that. Illustrator is especially excruciating to use. Another issue is that I can only run two CS2 apps at the same time never three. If I try, one of them randomly crashes. Reinstalls haven't cured it either.
I've called both Adobe and Apple in order to resolve the problem and neither have a solution. Adobe's view on it is that CS2 and earlier were not written to work on the Intel machine and so they cannot address any support problems with patches or updates. Their only solution is waiting until CS3 is released in Autumn which will be Intel compatible.
Based on this experience my advice would be to wait until CS3 is released before you buy one. Otherwise just grin and bear it if you have to have one now!

I have just got a intel imac and need a router to get on the net......

Obviously I want cheap! and its important that it will work too!

Please Help!!

Hi Harristotle,
Welcome to the forum.
The following link has some reviews which will help you decide:

You're looking at around 30 - 40 quid. If you shop around you may even find some cheaper. Obviously it would depend on what features you want (wireless etc) and there are more expensive models.

When i open my computer I get the white screen with apple symbol and there are vertical lines all over the screen with green pixels and after a few minutes the screen gets grey and I get message to restart my computer what happens

3 years ago I bought an IMac Desktop that I am using for a lot of things but the most important for dvd montage in Imovies and Idvd.
Now today when I opened my computer I get as usual the white screen with the Apple symbol but there were all over the screen vertical lines with green pixels and after a while the screen gets grey and I get message to restart my computer using the power button or the restart button and when I do so each time the same is happening somebody can tell me what is happening and what caused this. This computer is my work and now I have no income anymore.
On the Apple support site they are asking to enter the serial number and when I do so I get message it is wrong but it is the only one I have and I buy this computer in Cairo Egypt. I am living in Hurghada in Egypt for the moment. When I call the technical support of the shop where I buy it they are telling me that it is the hard disk or ram and that I probably lost everything on it and they are asking a big amount to repair.
Can somebody advise me on this matter. Thanks in advance

You can find the serial number either in About this Mc in the Menu bar under the , or it should be on a sticker under the foot of the machine.
If you have the install discs, try booting from them, holding down the c key and then using Disk Utility to check the drive.
You can also boot into Safe mode
To start up into Safe Mode (to "Safe Boot"), do this:
   1. Be sure the computer is shut down.
   2. Press the power button.
   3. Immediately after you hear the startup tone, press and hold the Shift key.
      Tip: The Shift key should be held as soon as possible after the startup tone but not before.
   4. Release the Shift key when you see the gray Apple and progress indicator (looks like a spinning gear).
During the startup in Mac OS X 10.2 through 10.3.9, you will see "Safe Boot" on the Mac OS X startup screen.
During the startup in Mac OS X 10.4 or later, you will see "Safe Boot" on the login window, which appears even if you normally log in automatically.
Please post back with results,
To leave Safe Mode in any version of Mac OS X, restart the computer normally, without holding any keys during startup.

TS2570 i have an intel imac and im getting a grey sceen. I get the flashing question mark folder. iv changed the H.D 2x and tired to install a new os into it but no luck. The mac isnt going into safe mode or anything. help?

Tired 5 keyboards on all Usb ports and a hub and keyboard wont boot to startup or safemode of anything but hub gets power. disc drive wont eject or accept a disc cuz keyboard commands not being sent to computer. Help?

Keyboards must be connected directly to the USB port, not through a hub.
Reinstall OS X without erasing the drive
Do the following:
1. 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.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

SilverKeeper backup doesn't work correctly with Intel iMac and 10.4.8

I use SilverKeeper 1.1.4 to backup daily to a LaCie drive. But it will no longer do automatic backups (that is, wake computer from sleep at 6am before I start the day) since I migrated from PowerBook G4 to new Intel iMac 24". It only starts the backup when I come and wake computer, not by itself, which it had done before...The SilverKeeper people have been unable to help me.
New Intel iMac 24" Mac OS X (10.4.8)

Could very well be that SilverKeeper's scheduling function no longer works with 10.4.8. Let me suggest alternatives that do:
1. Deja Vu
2. Synk (Backup, Standard, or Pro)
3. Synchronize! Pro X
All are universal binaries. You can find them at www.versiontracker.com or www.macupdate.com.

Trouble with intel iMacs and OD binding

When setting up 12 of our new iMacs at school this fall, I've run into a problem. Once bound to our OD server, the machines will hang intermittently during boot (before a login screen).
In this lab we have 16 eMacs running 10.4.7, and now 12 intel iMacs running 10.4.7. The OD server is 10.4.7 server.
All machines were first bound to our school's AD server and tested. All logged in for two days of students.
Then today the OD server was finally up and running for mcx settings. The 16 eMacs were added without problem. The iMacs were added, but now if they are restarted they often hang. Rebooting them may fix it. Sometimes they need to be rebooted several times.
Once an intel iMac makes it to the log in screen they act as they should. They authenticate first to AD, then get whatever mcx settings they need from the OD.
Tried: clearing out all bindings and caches and starting fresh.
Note: The OD master is not bound to the AD, The OD server's kerberos record is disabled as outlined in this help article (http://docs.info.apple.com/article.html?artnum=300765)
Any help?

You don't really need the old OS 9 printer utility - other than to know how many prints your printer has made. It prints fine in OS X at it's best resolution.
I am using this printer everyday w/ an intel iMac.
Of course ... you need to connect your 16/600 to your network through an ethernet hub.
In System Preferences - Network - make AppleTalk active.
Then go to the Print & Fax preferences and set up new printer.
The 16/600 will show up there.

Vertical Lines Started Appearing on my 17" Intel iMac and won't go away.
