Brand new iMac 24" 2.4 streaked dirty display

Hello: I apologize if this question has been previously asked, it appears that there are many display issues with these new iMacs...
I purchased an iMac 2.4/320GB HD/1GB RAM/256MB VRAM from the MacConnection on October 15, 2008. I've been having some issues with the display and was wondering if I could get any input.
The first problem I noticed when the machine was first powered up, there appears to be a speck of dust that is reflecting off of the glass panes so it actually looks like 2 specs of dust.
The second problem is that a fireworks/spider web type pattern has appeared on the left hand side of the screen (which seems to run a lot warmer than the right hand side) that has emerged in the couple of months I've had it.
Both issues appear to be on the inside of the glass, and earlier today I received instructions from a YouTube video on how to remove the glass with a suction cup. It appears that both of the problems are not on the inside of the outer glass, but they appear to be on the inside of the inner LCD display itself. I've only used the dampened cleaning cloth that came with the machine to clean all of these areas, but the streaks and dust are not going away.
I work with an Apple certified tech who told me to try a product called I-Kleer but it appears that all of the issues are within the inner screen. I'm aware that there's a year long limited factory warranty that comes with these models, I'm wondering if a problem like this would be covered? I did not purchase an AppleCare plan.
Any advice? I have a photo of what the screen is doing if needed.

Hi and thanks for the info. I tried a few things out and resorted to taking it to the Apple store for repair. Good thing I did - they had to replace not only the LCD panel, but the motherboard as well! Didn't have much info but I'm also thinking that a whole batch of them was affected. After a little investigating, it turned out that "spiderweb/fireworks" pattern I was seeing actually turned out to be an outline of my desktop wallpaper photo that was burning into the screen. Took a little while to figure out that was it, but I also started having the same problem some others have had posted in the forums with the screen burn-in. I jumped screens to a site with a dark background, and the eBay logo from the page I was on ten minutes previous jumped up and burned itself in the screen after I closed the window!
That was quite a major replacement of parts for a brand new machine and I'm thinking of selling it now. My model is a 2.4/320/4/256 with a beginning serial number of W8814. Definitely could be in the same lot as yours.
Thanks again for your help!

HT201250 I use Time Machine to back up my entire computer with my external hard drive. I am getting a brand new iMac this month and was wondering what is the process of using this back up to restore my new computer exactly how my old computer was?

I use Time Machine to back up my entire computer with my external hard drive. I am getting a brand new iMac this month and was wondering what is the process of using this back up to restore my new computer exactly how my old computer was? I want to make sure I will still have various important files on my new computer, like my songs in iTunes, my photos in iPhoto, etc, etc. Thanks so much in advance!

Welcome to the Apple Support Communities
When you turn on the new iMac for the first time, Setup Assistant will ask you to restore a backup, so connect the external disk and follow steps to restore all your files to your new iMac. Your new Mac will have the same settings and programs as your old computer.
In other cases, I would recommend to restore the whole backup without using Migration Assistant or Setup Assistant, but a Late 2012 iMac uses a special OS X build, so the OS X version that you're using on your old Mac won't work on the new one.

Brand new iMac freezes constantly! Updates aren't helping!

Hello everyone,
This past Sunday I bought a brand new iMac intel Core 2 Duo with a 250 GB HDD and 1 GB of RAM. At home I set it up with my SAMSUNG 1080p 22" monitor, Apple bluetooth Keyboard and mightymouse, and a Western Digital 350 GB HDD hooked up via USB. I was excited to finally jump on the intel-based Mac bandwagon, as well as experience dual monitors for the first time.
That was Sunday. Tuesday evening I was watching "Rome" on itunes on my Samsung monitor while surfing the web with Omniweb on the iMac monitor. All of sudden, everything locked up. I was able to move my cursor, but nothing responeded to my clicking. I hard booted the system and loaded everything I had going again, and sure enough, it locked up a few moments later. I ran system update, updated everything, then restarted. Time went by and although not immediatly, later that night it froze up on me again.
Fast forward to last nite, and the freezing reached and all time high. 5 times. Each time was when I had a browser open in my iMac window and I had Quicktime playing in my Samsung monitor. I was watching a sports program, with the player fit to the screen.
I have read many posts about intel iMacs freezing late last year, but there was a firmware update that evidently fixed that. I have this update installed, and I have had no luck. I have even contacted Apple Care via phone where I got instructed to unplug everything, plug it back in, start in safe mode, and delete cache. That didn't help me out at all. Am I right insuspecting I have a faulty Video card? I just ordered 4GB of RAM, could this be a RAM issue?

When diagnostics are run on a freezing computer and nothing shows, I'll put the program into a testing loop because this means one of two things: the issue is heat related so running the diagnostics several more times will bring on the heat so that the issue shows up or the installed RAM is marginal, just flaky enough to show up now and again but not so far off that a run through of the memory test catches it on the first run.
As I said in my original post, memory is always a suspect in a freezing or kernel panicking computer. And it does tend to top my list. But from what you describe I'm not quite willing to say, "Why don't you just wait until the RAM upgrade arrives?"

How do I uninstall Mavericks and recover Lion? I have a brand new iMac and web pages stall or freeze since I installed Mavericks. I can't get it to download software for my printer when I connect it.

I have a brand new iMac. It was working fine until I downloaded Mavericks. Now I have web pages that freeze while trying to load. The blue in the address bar stalls and freezes. If I try to load from page 1 to a later page, or reverse that, I also have the same problem. I tried to connect my printer for the first time, and again, the blue progress bar froze. Then I got the yellow triangle telling me there was a connection problem. My internet connection is via an Air Card as that is my only option where I live. I packed up the whole new iMac and took it to my Air Card provider, where they also have very fast Wifi, and they had the same problem with Wifi. I use my Air Card with my MacBook and it works JUST GREAT! I really want to return to Lion. HELP.

The only way to retutn to Lion is to format your drive (erase, lose all) and either:
1. clone back the clone copy i hoep you have, or
2. first backup your files, then format and install Lion again
But really, mavericks works great. You have a problem. Find out why. First, what unusual software do oyu have installed that may be conflicting with it? Virus, system modifiers, etc? Second what OLD software do you have that might be the problem. finally, you might need to do a re-install if something errored during install.

Photoshop CS6 keeps crashing. I am using a brand new IMAC, I have 16GB RAM recently updated as it was running slow with 8GB and lots of hardrive space. When it crashes, i lose all my presents and it changes my preferences, it also fails to save or produce

Photoshop CS6 keeps crashing. I am using a brand new IMAC, I have 16GB RAM recently updated as it was running slow with 8GB and lots of hardrive space. When it crashes, i lose all my presents and it changes my preferences, it also fails to save or produce a recovered file despite settings asking it to do so every 5 mins now. When i try to report the problem, it says it has found an issue and gives me a link to a solution....but wont let me click on the link.... PLEASE HELP! It's killing my productivity.

If the crash started right after you added RAM, it could be a bad Ram dimm. You can try this - change the amount of RAM in Photoshop to 4G, this should stop Photoshop from using the higher ram. If it doesn't crash, it's probably the ram. Or run a diagnostic app. You don't say when it crashes, what you're doing when it crashes - it there a pattern? Did it ever work on this computer? Did it work on your previous computer? Without a lot of data, it could be related to the new computer... What OS version? Did you recently update it? Have you updated Photoshop to the most recent update?
Do you have any plug-ins loaded? Try restarting Photoshop, and immediately press & hold the shfit key to turn off plug-ins.

Can I use Adobe Photoshop CS4 Extended on my brand new iMac? I had PS on my old Mac using the student licensing.

About four years ago, I purchased Adobe Photoshop CS4 Extended while I was in undergrad. I downloaded it to my Mac. Since then, I've purchased a brand new iMac. Can I use this same software? I know it's been four years so the software is very updated, AND my new iMac does NOT have a cd drive. This may all be in vain. I'm just clueless! Thanks!

Emalexander89 you are welcome to install Photoshop CS4 on your new Mac. You can download a fresh copy of the installation files at Download CS6 products.

Vmware fusion 5.0.2 cannot connect to network on my brand new iMac '27 late 2012

Dear friends,
I have tried to install Windows 8 (x64bit) Pro., Windows XP, and CentOS 6.0 using vmware fusion 5.0.2 over my brand new iMac '27 late 2012. However, neither one can connect to the Internet. There was no problem with the same installation on my iMac 2011.
The network board recognized by Windows 8 is Intel(R) 82574L Gigabit Network Connection.
In the folder of vmware fusion's setting files on Mac OS, I found a file called Windows 8 x64.vmx, and
there is a line as follows.
ethernet0.virtualDev ="e1000e"
Any friend has the same problem or can give me some hints?
Thanks a lot!

How to restore machine using a TM backup on a usb hard drive from older imac to a brand new iMac?

My imac (the one that had a superdrive in it), had a broken superdrive and was sent for repair. Whilst being "repaired" the screen was broken. I now have a brand new imac albeit without a dvd drive. My question is how to I restore my the old TM back up which had been made to an external usb hard drive to the new imac. Help files say that I should not restore from a TM file to a different machine and that I should use migration assistant. Whilst I can see the external usb drive in TM it is not being recognised in Migration assistant when I click on back up from a TM backup on another machine or disk.
Any ideas?
Just noticed that this new machine is running OSX 10.8.4 the broken imac was on mavericks

This is very simple first run Software Update on the new machine and get your machine upgraded to the most recent version of Mountain Lion 10.8.5. Install all other software updates Apple recommends in Software Update. Then care fully read Pondini's guide on using Migration Assistant located at:
http://pondini.org/OSX/MigrateLion.html
Your migrated data will be in a new account, to access it log into the new account.
Also DO NOT repeat DO NOTuse Wi-Fi to migrate data, if your TM backup drive uses USB, then connect it via USB and follow the on-screen instructions as described in Pondini's guide.

Brand new iMacs with Lion will not read DVD-R

Our business has just purchased 3 x brand new iMacs (3.4Ghz) pre-loaded with OSX Lion 10.7.2 and NONE of them will read a DVD-R containing important files I need to access. However, the trusty 2 year old iMac running Snow leopard sees the files instantly....what's wrong with Lion...?
My 2 year old MacBook pro was updated with Lion a few months ago and hey, it stopped reading DVD-R's....how interesting....! It can't be ALL of the superdrives failing, so it's obviously a fault with the OS...seems to be a VERY common problem, so what's the problem in getting it fixed?

Contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine.

My dad has a brand new iMac. If he quits an app, this window closes, but the app won't finish shutting down, Force quitting does not work. Once another app is opened, it will not close either. Now none of the apps are responding. Any ideas?

My dad has a brand new iMac. If he quits an app, this window closes, but the app won't finish shutting down, Force quitting does not work. Once another app is opened, it will not close either. Now none of the apps on the dock are responding. I asked him to click on the apple, and drop down to "About this Mac", but that wouldn't open either. Any ideas? If I was at his house, I would call Apple Care in a heartbeat, but am home with my sick daughter,,, Thanks!

For starters, have him open Disk Utility in Applications>Utilities, select the volume (the indented listing) and Verify Disk. If it reports any problems, have him try a Safe Boot by holding the Shift key at startup. This boot will take much longer than usual. It's checking and trying to repair the drive directory, if possible. Once in Safe Boot, have him repair Permissions.
For other Disk repair remedies see
http://support.apple.com/kb/TS1417
Also, have him try a PRAM Reset. At the startup chime, hold down CMD-Option-P-R together, listen for two more chimes, total three, then let go to finish booting.
Also, is he running any AV? If so, have him uninstall it. It might be responsible for this behavior. (There are no viruses for OS X.)

Slow performance, brand new iMac!

Hello!
First, excuse my rusty English.. I hope you manage to read it
Main problem.. Adobe, PhaseOne and other intensive applications is veeeery slow on a high specced brand new iMac! Lightroom 5, PS CC and Capture One Pro 7 is what I use mostly.
I just got my brand new iMac 2014.2 (3.5/3.9 GHz, 32 GB RAM, 512GB flash disk and GTX780M), and its quite a lot slower than my other Win7 workstation. Other workstation specs: i7 4.2 GHz, 16GB RAM, 128GB SSD, GTX 580. I'm working on the same Raid-5 drive (USB-3) too, so I don't know why it's slower..
What I experience:
Changing from "current" raw to next raw (while culling) takes several seconds, and my Raid-5 is done chewing long before I see the result on my monitor. I get the spinning beach ball while waiting for preview. I always render 1:1 on import and 1:1+standard size in menu, just to be sure. Adjustment brush is like dodging in PS v1.0 (NOT CS) when computers had less disk-space than we have cpu-cache today, awfully slow, and it "stutters". Moving/panning in 1:1 is very choppy, and sometimes I get the spinning beach ball while panning.. This happens in LR and CO.. Photoshop CC stutters or have to "think" when I try panning. These problems happens in 6 Mpix, 12 Mpix or 25 Mpix RAW files, and actually in some JPEGs too!
I have done following:
I've tried 2003 and 2010 processing in LR, small change. Fixed permissions in OS X. Removed preferences for LR, CO and PS CC. Reinstalled LR/cloud apps and Capture One Pro 7. Increased camera raw cache from 15 to 50 GB. Followed Adobe's guide to make LR faster. Followed Capture One guides. Reinstalled (clean install) of OS X. I've tried all tips I could find in the forums around.. I have also tried placing RAW files on internal 512 GB disk to see if that helps on performance, but no change. Same story with camera raw cache, doesn't matter where it is.
Additional things.. I’ve also diagnosed the iMac with checkdisk, memcheck, logs, etc.. No problems as far as I can see.
I just changed my workflow from Win to OS X and I depend on this to work.. I currently have 4000 files from my last job waiting to be worked on, and I'm not finished until Christmas in this tempo :-(
If I can't get this working very soon, then I have to return this very expensive iMac and buy a new PC again..

I have a brand new iMac that does not have iDVD. Made a move on iMovie installed a 3rd party burn prog. but DVD won't playback on my regular dvd player. Need to burn one that will. Help!

My new iMac did not come with iDVD as they are not using iDVD any longer. I made a movie that I needed to put on a DVD that would play on any external DVD player. After calling Apple twice, they recommened a 3rd party program so I downloaded "Burn-osx" and made the DVD; however when i insert it into my player connected to the TV it gives the message "disk error --playback feature may not be available on this disk". Ok--now what? I am up against a time line here--need the DVD for a graduation party! Help! What am I not doing correctly?

I have a brand new iMac
If you are still within your 15 day return period. Call Apple they will sent out iDVD at no charge. (There are no realistic substitutes.)
Nicely explain that you may return the computer without iDVD. That usually does the trick. You MUST speak to a senior advisor to get a free copy. The first tier people cannot do it.
408-996-1010
800-692-7753
If that doesn't work you can purchase iLife 11 (includes iDVD) on disk.
IDVD is a wonderful piece of software and well worth the low cost of $40.

they recommened a 3rd party program so I downloaded "Burn-osx"
Yes, there are programs that will put a movie on a DVD. I have tried most of the other substitutes including Toast, Burn, and others. None of them come anywhere near the ease-of-use and power of iDVD. IDVD is specifically designed to work with iMovie. Get iDVD.

My brand new iMac track pad reverted to a system preference option that doesn't allow gestures to work or be restored, any suggestions?

I purchased a brand new IMac 21 inch a few weeks ago and restored it to my macbook pro. A few days later the gestures on the track pad stopped working. After listening to the advice of apple support and wasting a number of hours without success, I decided to restore the computer to new and start fresh. The outcome was the track pad worked just fine. I noticed the system preferences track pad choice provided options that I didn't have before. All worked fine and of course from their I migrated apps and documents from my time machine. a few days later I plugged my ipod in and noticed the track pad was not working.
Having spent another two hours with apple support, they concluded they would call me back as they agreed that the system preferences setup for the trackpad had reverted to an older version.
I am not certain if migrating the apps folder had anything to do with this and am waiting to hear back. I am tempted to restore the machine to new again and see if that restores the track pad system preferences. If it does I will avoid migrating any files to see how long the track pad works. I have my docs, photos, and other critical folders backed up individually on a separate drive. Let me know if anyone has experienced a similar problem. Thanks!

Have you tried all of these?
1. Pressing the Eject key while opening the iMac.
2. Pressing the Eject key while closing down the iMac.
3. Holding down the Option key while restarting the iMac.
4. Using Disk Utility to try to Mount, Repair and Eject the disk.
5. Holding down the Mouse while restarting the iMac.
6. Pressing the O and F keys while closing down the iMac.
7. Opened Applications > Utilities >Terminal and typed in 'drutil tray eject'.

Can't partition HD with Bootcamp Assistant on brand new iMac

I just got a 27" 1TB brand new iMac three days ago. After copying over all my files from my previous computer (PC), installing some software packages and configured the Mac the way I want it, yesterday I wanted to partition 80GB out of remaining 330GB with bootcamp assistant to install Windows 7. After one hour it stopped with an error message that it wasn't able to move some files and I would need to re-format the HD and start again.
Is there really no other way? It took me two days to get to where I am.

It should only take less than a minute.
So just use OS X software to clone what you have to another hard drive, then do an erase and restore.
And backup before starting is at the top of the list of things to do to prepare.
http://www.apple.com/support/bootcamp - re-read the pdf guide linked at the top and other tech articles.
And you really do want bootable clone image of Mac OS anyway, in addition to or in place of TimeMachine, so no loss in doing so. It isn't as if you will lose or have to redo.
It needed contiguous free space and no files at the end of the disk. But installers and updates do scatter files and fragment free space a lot and can leave files locked where they can't be moved.
SuperDuper
Carbon Copy Cloner
iDefrag
iPartition
Apple Disk Utility Restore
And you can have OS X on multiple hard drives, plus it really helps for doing the type of maintenance and repairs needed for updates and proper running.

Brand new iMac 27 has no sound

A buddy just got a brand new iMac 27, out the box last night. It has no sound.
He went to Systems Preferences and the Sound page provides no solution. Nothing can be clicked.
I know the solution is probably insanely simple, but cannot figure it out.
Help please.

The simple solution is take it back to Apple and ask them to fix it.
