My 24" imac has a dim or yellowish cast

I just bought a Mid 2007 (Model MA878LL) iMac on Ebay.
The screen is dimmer than normal has has a yellowish cast or like it needs "it's teeth cleaned".
It's not confined to one area or the edges, it's the complete screen.
I've run all the updates and tried calibrating the display with no improvement.
Before I contact the seller or Ebay is there anything else I can do?

Yes, I tried doing all those normal things.
If someone was not used to this computer they might not have noticed although it certainly does not "pop"
I noticed it being dingy as soon as I turned it on and I also have another 24" next to it. There is a big difference.
I suspect the seller was getting rid of a leon.

For anyone else reading this thread, it is worth knowing that sometimes an email is, or can be, corrupted thereby jamming the works. The solution above is good, but I just wanted to suggest another one.
If the problem arises, go to an online mail access service, such as Mail2Web.com and login to you mail account there and delete the offending message.
Problem solved.
And George, as this is all entirely voluntary, whinging about no takers may not endear people to you. Besides which, a few minutes of searching on Google would have found you a number of solutions.

My new iMac has recently had OSX Lion installed on it and now when I start the machine it looks like its updating something every time, and the wireless doesn't work. So I restart and everything is OK - until I have to start up again the next time?

My new iMac has recently had OSX Lion installed on it and now when I start the machine it looks like its updating something every time, and the wireless doesn't work. So I restart and everything is OK - until I have to start up again the next time - then I have to repeat this again! Any help appreciated.

I've been having the same issue, but have just discovered something on my own that hasn't been pointed out in any of the forums I've visited. In what I thought would be a vain attempt to help myself, I went to System Preferences, Users & Groups, and then clicked on Login Items. I discovered that one of the Items that was listed to open automatically upon login was iTunes Helper and that there was an exclamation point beside it indicating that it was incompatible. I simply deleted that item and now I don't have the situation you described and my wireless is connected. Hope this helps!

IMac has become slow and freezes up

For a few months now my iMac has been much slower than it used to be. Apps take longer to open, menu functions respond more slowly, folders and files take longer to open, pages longer to display, etc. Frequently the active window freezes and the colour wheel starts spinning for 10-15 seconds (it has been doing it twice since I started writing this sentence). This happens with all apps I am using, like Safari, Mail, Word and Excel, but particularly frequently in Logic Pro X. Sometimes when it happens (but not always), I get the error message "Disk too slow or system overload (-10010)". However, I upgraded to Logic Pro X about a year ago, and I never had this problem during the first number of months after the upgrade. I am aware that Logic uses a lot of CPU and memory, but, as mentioned, I also have the problem when Logic is not running. This leads me to think there might be something with the hard disk, although it beats me why it suddenly should have become slow. I am currently running everything from the built-in 1 TB hard disk. I have a 3.1 GHz Intel Core i5 CPU and 8 GB RAM. A full EtreCheck report with my system specifics is enclosed below. Can anyone help?

Hello,
My old emails address which I have used as my apple id for 10 years is being made redundant. I have changed the email address to a new gmail one and this is my new apple id. But my iMac has not recognised this. It keeps saying it wants the password for my old email address. I have seen some advice on these forums which suggest signing out of iCloud and then back in again. But when I start doing this it asks me if i want all the photos deleted that have not been downloaded onto the mac.
I have had an iCloud account for quite sometime and I'm afraid of losing everything in my cloud if i sign out and sign in with a new id.
Is this fear realistic?
I know I can change back to my old email, sign out and then sign in wight he new one...
Please help!

This did not work for me. My old email account for iCloud still pops up on my screen every time I open my macbook. I've deleted it, reset it, every thing I can think of and it still shows up. I think six months of this is more than enough time to wait.

imessage on my iMac has created two iMessage account both asking for Apple ID....and no option to - (delete) one of the two duplicate accounts....how can I delete one of them it just bothers me due to sign in issues....when signed into one it signs out the other and goes inactive I just wanted to delete one of them so this issue doesn't happen....why doesn't it give the option to delete ONLY these two accounts

1. Don't confuse "Apple ID" with iTunes Account ID. You can have many Apple IDs but only one iTunes account active at a time.
2. If you "changed" your iTunes account ID, you actually have 2 accounts - one under the old name plus the new name.
3. You can't merge the accounts - they remain separate. Apps purcahsed under the old account name will update ONLY WHEN THE PHONE IS SIGNED IN TO THE OLD ACCOUNT NAME and visa versa.
4. Likewise, you can sync only the apps, music, media purchased under the account the phone AND iTunes are signed in to.

I have no idea whether there is a causal relationship but since moving to Lion and iCloud, my iMac has become so unresponsive that I wind up having to crash and restart most of the time. This is true regardless of the app I am using at the time.
The specs of this iMac are:
iMac 27 inch, late 2009 model with a 3.0 GHz Intel Core 2 Duo with 4 Gig 1067 Mhz DDR3, using OSX Lion 10.7.4 (11E53)
I have Mackeeper installed and according to the scans I have run, everything is fine. No virus, no junk files . . . no problems at all . . .
Except that for all practical purposes, my computer isn't working.
I am nearly totally deaf and live in an isolated, rural area of NW Missouri and this computer is what I mainly rely on to contact friends, relatives and business associtates!
Any and all suggestions will be greatly appreciated!

First, back up all data immediately, as your boot drive may be failing.
If you have more than ten or so files or folders on your Desktop, move them, temporarily at least, somewhere else in your home folder.
If iCloud is enabled, disable it.
Disconnect all wired peripherals except keyboard, mouse, and monitor, if applicable. Launch the usual set of applications you use when you notice the problem.
Step 1
Launch the Activity Monitor 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.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Activity Monitor in the page that opens.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Step 2
You must be logged in as an administrator to carry out this step.
Launch the Console application in the same way as above. 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.
Post the 50 or so most recent messages in the log — the text, please, not a screenshot.

My iMac suddenly no longer connects to wifi network when in KIOSK (username) mode, and only connects when as ADMINISTRATOR mode. Its strange because the iMac has been working fine in KIOSK mode for over a year until 2 days ago.

One of the memory cards was indeed faulty, and the other completely fine
Thanks very much for all your help!
Although there is one little thing that I've noticed. The iMac works properly, but I tried to software update to see if that may help my Minecraft sound issue (as I still don't think only having 2GB instead of 4GB would cause such a problem) but the software update application won't work. Running the "Software Update" from the apple menu on the toolbar gains no response, nothing happens. If I run the software update from system preferences, the application icon appears for a second, then disappears (as in the blank app. icon, the blank canvas with the pencil, pen and ruler in the bottom right corner). It does this every time I try to run it. It did work when the computer was crashing, but this started when on one of the occasions I ran the app. while it was crashing. Since this occured during the crashes, and still occurs now, I'm wondering did something simlar happen minecraft, as it's sound disappeared during the crashes and is still gone now.
However, the computer is now working again without crashes, which is the main thing, thanks for helping me fix the issue
Edit: I would mark the topic as solved, but I'm unsure if this would lock the topic or something simlar, so I'd rather leave it open for any ideas regarding the software update and Minecraft issues I'm having

Restart your router as well as your Mac and printer.
If that doesn't help, try wireless diagnostics.

Turn Time Machine OFF temporarily in its preference pane. Leave the window open.
Navigate in the Finder to your backup disk, and then to the folder named "Backups.backupdb" at the top level of the volume. If you back up over a network, you'll first have to mount the disk image file containing your backups by double-clicking it. Descend into the folder until you see the snapshots, which are represented by folders with a name that begins with the date of the snapshot. Find the one you want to restore from. There's a link named "Latest" representing the most recent snapshot. Use that one, if possible. Otherwise, you'll have to remember the date of the snapshot you choose.
Inside the snapshot folder is a folder hierarchy like the one on the source volume. Find one of the items you can't restore and select it. Open the Info dialog for the selected item. In the Sharing & Permissions section, you may see an entry in the access list that shows "Fetching…" in the Name column. If so, click the lock icon in the lower right corner of the dialog and authenticate. Then delete the "Fetching…" item from the access list. Give yourself read access if you don't already have it. Click the gear icon below the list and select Apply to enclosed items from the popup menu.
Now you should be able either to copy the item in the Finder or to restore it in the time-travel view. If you use the time-travel view, be sure to select the snapshot you just modified. If successful, repeat the operation with the other items you were unable to restore. You can select multiple items in the Finder and open a single Info dialog for all of them by pressing the key combination option-command-I.
When you're done, turn TM back ON and close its preference pane.

Boot off your *original* Install Disk while holding down the *d key*, (not c key), then run the extended Apple Hardware Test. Some disks require you to use the Option key at bootup to select AHT. Some models have a separate AHT CD. Some have it on the Disc #2.
The Memory test can really only be trusted if it finds a problem, not if it doesn't find a problem.
