Apple iMac "Core 2 Duo" 2.66 20-Inch (Early 2009) display problems

I have a Apple iMac "Core 2 Duo" 2.66 20-Inch (Early 2009) whose screen has gone partially black to be more specific the bottom half of the screen, the screen is split almost in half the top half working fine and the bottom half completely black. The screen does not appear to be crack. Screen went half black while on itunes one day and has been that way ever since, any idea what it could be? (if you go to my profile a picture of the screen is provided)

Thanks for the response, I just installed Snow leopard (10.6.8) but the issue is when I go to the apple store and tried to download Yosemite, I don't see the option to download it. Looked around everywhere and no luck. What I'm doing wrong? I tried also the software update and I just get to the page where says no updates available and shows Yosemite as a free upgrade but when I click on the button nothing happens.
Any help would be really appreciated.

How to install osx 10.6 on Apple iMac "Core Duo" 1.83 with 1 gb ram

Apple iMac "Core Duo" 1.83 with 1GM Ram and Preinstalled Tiger 10.4.11,
How can i Install leopard 10.6 on this imac, please give me the link also to osx 10.6

You can purchase 10.6 from the Apple on-line store for $30. Also, OWC, www.macsales.com sells it for $26.
You would be better off with more memory, 2-4 GB would be important.

Can Apple iMac 9,1 Core 2 Duo 2.66 20-Inch (Early 2009) run OX mavericks?

I have a 9,1 iMac. It is currently running 10.5.8 I want to upgrade it to the latest one mavericks. Is this possible with the iMac I have and if it is then how do I do it.

Yes. Both 20" and 24". Be aware that many apps that you have for Leopard will not function with Mavericks and may be costly to replace.
You can upgrade to Snow leopard by buying the disk from your national Apple on Line store. Be sure to have all your machine details ready. When that is installed you can go via the App store directly to Mountain Lion and onwards to Mavericks.
You can check your apps status through this resource.
Application compatibility table - RoaringApps
Once again, I would advise you think this through. Mavericks is new and currently subject to much critisism. I would wait until the second update and read up about it.

What can I do about my 20 inch iMac (Core Duo) doing a LOT of disk activity?

Is there some built-in Optimization software I should use?

Microphone and iSight on iMac Core Duo

I am planning to buy a 20" iMac Core Duo and would appreciate hearing about users experience with the built-in mic and iSight. Specifically:
1. I've had problems with PC mics not picking up people speaking unless they have the mic very close to their mouths (1-3 inches). Does the built-in mic on the iMac work well for someone talking at normal volume and at typical distance from the screen - eg sitting at a desk? Can it pick up speech from further away - eg roughly 3-5 feet from the mic?
2. What is the advantage of buying the USB iSight camera over the built-in iSight camera aside from the ability to move the camera around? Picture quality? Or is there some other advantage?
Thanks.

When it comes to the mic it picks up EVERYTHING. I sit about 2 feet from my iMac and I have no problems when I have audio chats with other people. I have had people talk from over ten feet away and it comes in clear enough. Its safe to say the mic won't be an issue. As for the camera apple claimed it should be slightly better than the external firewire iSight. I never owned the older one so I wouldn't really know. The only advantage to the built in one is there are no extra cables dangling around and you don't have to go out and spend the extra $120. In terms of moving the camera around, I haven't had any trouble in getting it to point where I need it to, unless you need it to point at the screen. The computer turns, and tilts easy enough so its really not an issue.

Nikon Coolscan V ED and iMac Core Duo

Anybody using their Coolscan V ED, or another film or flatbed scanner, with the new iMac Core Duo? I plan purchasing the CS V ED in the very near future, but unsure whether it will work well with the new iMac.

Here is my little exchange with Nikon today...
After they referred me to the FAQ that I already read.
ME: "Thank-you for your reply but I still think you've failed to answer my question. The article you refer me to with your link is main reason I contacted you. I'd like you to escalate this issue to somebody that can answer my questions in more detail...
Which BRAND-NEW Macintosh computers are supported with the Nikon LS5000 scanners?
Does Nikon intend to support Mac? If so, then when, since all new Macintosh computers now have Intel processors?
It's already been four months of new Intel Macs, I'd expect Nikon to have at least some small idea of how much longer would before the Mac platform is again supported?
What's even more disturbing is that I only stumbled upon this issue by browsing this support forum. I was on the verge of purchasing at least four and possibly up to eight scanners and corresponding computers. That would have been a financial disaster for my company considering the lack of support and the seeming lack of concern by Nikon regarding the new Mac computers.
NOWHERE in your sales literature or the Nikon Coolscan website does it say that Macs with Intel processors are not supported. The sales literature only states that Macs require at least a G3 processor or better. Most people would read that and assume that a brand new Mac with the latest processor would be better than a G3.
Shame on Nikon for hiding this issue under the rug and not providing a prompt solution for their very loyal customers."
NIKON: "Hello,
These days new operating system version pop up every other week.
We strive to keep our products up to date with the latest operating systems out there, and work closely with Microsoft and Apple to see that this support comes as quickly as possible.
Apple is still offering systems with the PowerPC processors, like the iBook G4, Power Book G4, and the Power Mac G5.
As of today, we do not support the new Mac systems with the Intel chipset, but this is currently being looked into. We have no other information to offer at this time.
Thank you,
Dave"
ME: "These days new operating system version pop up every other week." LOL- You must be thinking of Windows where there are nearly a dozen versions not counting the new Vista.
But I understand. Nikon is working on it and you have no further information. That's fine.
However, your sales literature is seriously flawed. It says that the scanner will be compatible with a G3 or better processor. If your equipment doesn't work with the newer Intel processor, then it's NOT compatible with a G3 or better; it's ONLY compatible with a G3, G4, & G5.
My complaint is that you should either make a note in your literature at least for your vendors or issue an estimated date of when you're going to fix the problem.
As I explained, this is a PRE-SALES question and your attitude towards me is troubling. I was looking to purchase between four and eight of these scanners and because of inaccurate information in YOUR brochures, I almost purchased thousands of dollars of useless computer systems.
Maybe you should forward my question up the chain of command at Nikon... to somebody that cares more about what POTENTIAL customers think.
Meanwhile, I will post this issue at dozens of Mac user forums so that others don't make a big mistake by thinking a new Nikon scanner will work on their new Mac computer system.
NIKON: "Hello,
We certainly do care about potential customers, which is why we will not offer any software that is not ready to be released. Software development takes a very long time to finalize, and involves a huge amount of testing before it is published publicly. Our timetable for software release for this new technology is unclear at this point, and we apologize for that.
As for the product literature, it will be updated to include this new item in time, and our vendors are supplied with up to date support information on a regular basis. At the time of publication, all information on the brochures was correct and up to date.
Thank you for pointing that out, however, and I will be happy to pass your comments onto our QA team for review.
Regards,
Dave"
I think everyone with a Nikon Scanner who is considering the purchase of an Intel Mac or vice-versa should send Nikon a flood of complaints regarding the issue. How long can this really take them? The new Macs have been out for quite a while now.
In my experience, Nikon has excellent equipment but once they identify an issue, they do nothing to resolve it. It gets swept under until the next scanner is released.
Example: The older LS-4000 scanner had firewire communication "issues". Issues that were never fully resolved but the LS-5000 scanner is now USB-2.0

Screen unevenness on iMac Core Duo 20. What to do?

Hi Guys,
I got my first iMac Core Duo 20 last Thursday. Everything is beautiful except the screen, which had pretty bad screen unevenness at the two bottom corners. I took it back today and exchanged it for a new one. But it seems this new one is even worse. It's so bad that when I try to play a widescreen video, the entire bottom black bar appears to be light grey.
I am now a little afraid to get another 20 and experience the same problem. Is the 17 inch iMac better in this regard? My girlfriend's iMac G5 20 doesn't have this problem at all. Is this maybe just a bad batch I ran into? I know some uneveness is unavoidable on consumer LCD panels but what I saw on these two iMacs were just too impossible to live with. iMac Core Duo 20 owners, what are your experiences?
Thank you all in advance!

It is under warrantee, take it back until you get what you have paid for. Have them test a new one in the store before you take it home.
BTW, mine has worked great from day one!

I have installed Lion on an iMac Core duo by mistake - how do I rectify..?

I have installed Lion on an iMac Core Duo, via firewire from an iMac i7.
The Core Duo now goes to grey screen, folder with "?", then the "prohibited" sign for a 30 secs and then turns off,
(I now realise Lion is 64bit and the core duo only supports 32bit...).
The core duo will chime but will not boot off the original install disk or mount as a fire wire target disk.
How do I wipe Lion and reinstall Leopard...?

Sounds like hardware error.
Maybe the target-mode did something bad to the EFI, like fed it 210 proof "Everclear" ...
Try a diferent USB keyboard ...
Last resort for me before Genius Bar is either SMC Reset (http://support.apple.com/kb/HT3964) and/or PRAM reset (http://docs.info.apple.com/article.html?path=Mac/10.7/en/mh26871.html).
I am out of ideas if the resets cannot bring back "C" boot.

Imac Core Duo Crashing ......A Cry For Help

I received my eagerly awaited iMac core duo 17' 160gb. I took it out of the box and it work away fine. When I was installing Norton Anti Virus the installer quit before the full install was complete. I then restarted the iMac and the welcome to OS X progress bar completes and after that all that appears is a blue screen. I do have mouse movement but no login window appears. I have tried reinstalling the OS X software from the software restore disc that came with the iMac but this did not fix the problem. I then opened disk utilty on the the software restore disk and did what first aid was available on this disk, but again no fix. I tried booting from a Disk Warrior bootable disk but this disk will not boot. Through total desperation I opened disk utilty on the restore disk and went to intialise the drive, but the drive will not erase.
All suggestions of a fix or any assistance in fixing this issue would be greatly appreciated. To say that I an frustrated,stressed and demented over this would be a understatement.
Thanks in Advance

Last time I installed Anti-Virus on one of my Mac's. It was a terrible experience on my G5. Not to say AntiVirus is bad to install, but currently there is absolutely no reason to install one.
Really... don't waste money or cpu cycles on antivirus until there is a reason, right now there is this golden halo that protects mac from viruses. I really don't know why mac's rarely if ever have a virus, but I really don't question it either.

Printer recommendations for iMAc Core Duo

Greetings! I need a recommendation from anyone who is successfully using a multi function printer with an iMac Core Duo. I am returning an EPSON CX5800f because the scanning driver does not work. The printer works great but the scanner does not. Any success stories? Thanks Billy D

Hello, again! I am back. I returned the EPSON today and I am looking at an HP OfficeJet 7310 for printing, faxing, and scannng on my iMac Core Duo running OS 10.4.6. Any one with good or bad experiences with the 7310? I received an email back from HP saying that the 7310 would work with Intel Macs but I see no such indication on their web site driver download page. Plus HP has not said that the scanning driver for the 7310 would work with the iMac Core Duo. Any comments? Thanks!

External Hard Drive and iMac Core Duo

I purchased a new iMac Core Duo and also have a iMac G4.
I transferred my data from the old computer to the Core Duo with no problems. I have a Maxtor One Touch II external hard drive on the old mac. Everything transferred well including the external hard drive.... everything worked well until yesterday. Something happened, I don't know what. The Core Duo no longer recognizes my external drive, and I can't reload it. I tried to migrate all of my files from the old mac to the new, But that doesn't work anymore either. Does anyone have any suggestions? I have an awful lot of data that I really would like to have again on the new Core Duo.

I think my new iMac just fried my external Lacie d2. I kept my iphoto library on the d2 and was working in iphoto and suddenly photos started disappearing. When I rebooted, the drive was fried. Disk Utility couldn't repair it.

Anyone have the iMac Core Duo Ship Yet?

Hi Everyone.
Well, I'm as excited as most everyone about the iMac Core Duo.
Just curious, if there are any shipping reports yet? Any of you had yours ship yet? I hope it starts soon!

Mine in the UK is stating an estimated shipping date of Feb 8th, but then it is fully loaded except modem & iWorks.

Can the imac core duo support dual band wifi?

I have a core duo 2GHz iMac intel. Can the imac core duo support dual band wifi?

Do you mean will your iMac work with a router that supports dual band? If this is correct, the answer is yes. If that isn't what you intended please look at the system specification for your machine. You can find that by clicking Support - Tech Specs

Snow Leopard on a 1.83 White iMac Core Duo w/ GMA 950 Integrated Graphics?

Hi. My parent's computer is an older, white iMac with a GMA 950 integrated graphics. Currently it's running Tiger and it runs very well.
However, I am in town for a short bit and was thinking about updating their system while I'm here. Does the iMac 1.83 with integrated graphics run Snow Leopard very well? Or should I just leave Tiger on it?

Anyone with a 1.83 iMac Core Duo with integrated graphics (NOT the ATX 128 mb graphics) running Snow Leopard?
