My imac 17' core duo 1.8ghz a1173 freezes after about 1 minute of running

My imac 17" core duo 1.8ghz A1173 freezes after about 1 minute of running. I re-start the imac about a half a dozen times and it stays running and will re-start from the sleep mode and will continue to operate properly until I put it in sleep mode or it goes to sleep mode. If I turn it off, I must go through the same hassle. Advise/suggestions. Thanks.

Imac 17" core duo 1.83ghz broken display how to connect external display?

Hi there! I have a 2006 Imac 17" core duo and the screen broke by accident. The repair costs are extremely high and thus I was thinking about buying an external display and hooking it up to the imac. Firstly, would such a thing be possible, and if indeed possible how would one go about setting it up?

PowerMac G5 vs iMac Intel Core Duo

Hello, I currently have a PowerMac G5 Dual Core and am thinking of getting another computer. I have a question. In terms of performance, what is faster, the G5 (Dual) on the PowerMac or the Intel Core Duo on the iMac (running at the same speed).
And at the bottomline, what would be the machine that I want for gaming, publishing, and video editing? The PowerMac G5 (Dual) or the iMac with Intel.
Thanks for the assistance!! Have a good one.
P.S. Are there any plans of releasing a PowerMac with an Intel processor.
PowerMac G5 Mac OS X (10.4.6)
PowerMac G5 Mac OS X (10.4.6)

(Oh...right...sorry for mentioning that) Thanks for hte response!
Anyways, I just want a computer that will not be outdated for a while. I don't want to purchase the G5, and then months down the road, not see the G5 in production anymore.
One thing about the iMac I'm not too fond of is the lack of upgradibility (or so it seems so). Due to it's size, it would be very difficult for someone to upgrade it's internal components.
I will be purchasing either today evening of tommorow, and I want to know what will be my best choice for the future, the iMac Intel Core Duo or the PowerMac G5.
I always thought of the PowerMac G5 as a beast, and I still do, but some of the latest reviews and benchmark tests I have seen have said that the iMac (with Intel Core Duo) has performed very close to the PowerMac.

Quark 6.5 crashes when opening existing files on iMac Intel Core Duo

I just switched from a G4 titanium laptop to an Intel iMac and Quark works fine except when I try to open a file that I created on the laptop (same Quark 6.5). It crashes. I talked to Quark and they said that I need to open the files on a PC and resave (I don't have a PC or a friend with a PC and Quark not that I'd send them all my files even if I did). I've tried resaving and renaming files with no luck. I tried reinstalling both the operating system and Quark (both 6 and 6.5) with no luck. Has anybody else had this problem and found a work around? I want to sell my laptop but I can't until I know I can access the hundreds of client files I have there.
iMac Intel Core Duo Mac OS X (10.4.6)

Sorry I have no real experience with this, just a thought. Did you use migration assistant to move the old files over from your G4 to your Intel? And did you then perform a "Repair Disk Permissions" upon the entire hard drive from within Disk Utility's "First Aid" panel? (located at Applications>Utilities>Disk Utility)
If the file move still is causing you a problem afterwards, you could try and work around it by moving the files in a different way. As a test, create a small file on the G4 and then email it to yourself from the G4. Receive that message into the Intel and see if the Intel can then open the file from inside Mail. This might avoid any "bias" created during the move from old to new Mac.

IMac 17" Core Duo acting slower than it should-

My father has a first generation iMac 17" Core Duo. It should be really fast. (At least compared to my PMG4 MDD..) I think it is rather fast, but sometimes it is really slow. Spinning ball while changing application, spinning ball while opening applications, spinning ball while performing operations in applications.. However, when I checked last night, the CPU was typically used about 20-30%. About 5 MiB free RAM, and about 100 MiB inactive.
I get the impression that the computer is way faster before the Office suite is launched. Dad is always running Entourage, and often both Word and Excel as well.
Is it likely that this is the explaination? That the computer is slower when an Office app is running? MS states that it "should run well under Rosetta", but on the other hand, they're known for their BS.

Yes, that could very well be the problem, especially
if the computer only has 512 MB of RAM.
It has. Though I find it a little bit peculiar that it can have as much as 100+ MiB inactive RAM and still be slow.. I thought inactive RAM was RAM that could be re-used, like free?

IMac Intel Core Duo Hard Drive Replacement

I may need to replace my iMac (Intel Core Duo) HD soon; I'm wondering whether the Geek Squad does work on Macs. Also, is this something a person can do themselves with good directions, or is that risky. I've put in memory, but think the HD is probably a step up. I have everything backed up and would get all my stuff back on HD myself. Has anyone had experience with Mac repair here?
Solved!
Go to Solution.

Welcome, Selia!
We certainly do work on Macintosh computers. The criteria is: "Is the part user-serviceable?" We would need to sendthe unit in for upgrade to our repair center if it is not something Apple has in their DIY section of their website. This is toensure consistency and to avoid any issues if still under warranty. Typically only Mac Book laptop hard drives areserviceable in the store.
Either way, I recommend letting an Agent assist you in the store. Let us know if you need further answers.

IMac Intel Core Duo: Which Install DVD disks should I be looking for?

I have an iMac Intel Core Duo (2 Ghz, 20") model. This was sent to me from Apple as a replacement for my iMac G5 when it had problems a couple years ago. I just realized today that they did not send me OS install disks for it; I still have the iMac G5 install disks though.
What iMac install disks should be looking for to purchase? Are they specific to an Intel Core Duo? Would any iMac Intel installation disk work?
Thanks in advance.

You may be able to contact Apple and have them provide a replacement set for a nominal fee.
If it's the Core Duo white iMac from +early 2006+, it came with Tiger (10.4). Therefore, you can get install Leopard or the current Snow Leopard on it. You just need the standard retail disc.
Would any iMac Intel installation disk work?
Usually, installation discs that come with Macs (the grey ones) only work with that specific Mac model. A retail disc (the ones that are sold separately) will work with any supported Mac model.
There is another difference. The disc that is included with Macs also have additional bundled apps, such as the iLife suite. The original included disc for your iMac would have iLife '06, which is two versions old, so it may not be that much of a benefit today (iLife '09 is the current version).

External Drive Recommendations for iMovie '09 and iMac Intel Core Duo

I just got a new iMac Intel Core Duo, and loading up on 4 gig of Ram. Going to get an external drive to house video footage, and wondering if this model might be ok. I understand firewire is usually better than usb drives, but am looking at one that is USB 2.0 with of speeds up to 480 Mbps and transfer rates up to 1.5 Gbps. Claims it's almost twice as fast as FireWire 800.
Would this work well for iMovie, editing HD footage?
Thanks in advance for your replies.

LOVE this Fantom drive. Very quiet and an amazing price for 1TB with all interfaces.

What is the most effective way to get my imac 2 ghz intel core duo 2 10.4.11 to be able to run 10.5 and sync with my iphone 4s?

What is the most effective way to get my imac 2 ghz intel core duo 2 10.4.11 to be able to run 10.5 and sync with my iphone 4s?

As your Mac should run Snow Leopard provided it has at least 1GB memory, that would be a good deal easier and very much cheaper than trying to find a 10.5 install disc.
Snow Leopard costs $30 approx from the online Apple store (£26 if you're in UK)
You'll need to update Tiger to 10.4.11 with the combo installer first (unless you're just erasing the disc and starting fresh) You can then update SL from 10.6.3 to 10.6.8 with its combo installer.
For comparison, 10.5 Leopard is currently running about $130 from Apple (if still available) and more on Amazon etc.
This info for Leopard courtesy of TexasMacMan;

http://support.apple.com/kb/TA24950
Leopard is no longer available at the Apple Store but may be available by calling Apple Phone Sales @ 1-800-MY-APPLE (1-800-692-7753).
If you can't obtain a retail install DVD from Apple, look on eBay or Google the installer part numbers to possibly find at an on-line store. Here's what to look for:
MB427Z/A Leopard 10.5.1 install DVD
MB576Z/A Leopard 10.5.4 install DVD
MB021Z/A Leopard 10.5.6 install DVD (single user)
MB022Z/A Leopard 10.5.6 install DVD (5-user family pack)

EA Game (Harry Potter Deluxe Edition) will not play on iMac Intel Core Duo

I have repeatedly tried opening the EA/Aspyr Harry Potter games (Sorcerer's Stone and Chamber of Secrets) on my iMac intel core duo. It fails to open, with all attempts ending in a window that tells me it has failed and offering the option to cancel, retry, or report problem to Apple. This occurs with both discs/games. Is the software simply not advanced enough for the new iMac? Has anyone opened this at all?
PowerBook G4 Mac OS X (10.4.7)

They are both Aspyr ports of EA games. I've run both on my G4 Macs in the past but can't comment on their compatibility with the Intel processor.

Imac intel core duo 20" bug graphics

bonjour,
jespere que vous comprenez le francais
j'ai un imac intel core duo 2ghz, 1go de ram dd2 osx 10,4,9
j'ai un soucis quand je joue a world of warcraft, l'ecran se brouille, ne nombreux traits apparaissent, impossible de voir en fait le jeu correctement, obligé de faire un pomme+m et de revenir en full screen apres, et ca repart.
sachant que le jeu passe en full quality a 30fps a peu pres, j'ai essayé de tout baissé au niveau qualité et rien a faire.
je n'est pas eut le temps d'essayer d'autres jeux.
je n'est pas essayer en redemarrant sous windobe.
l'ordinateur est encore sous garantie.
dites moi tout ce que vous savez
merci d'avance.
a bientot.

Depends on how intensive you plan on getting with the iMac. For the most part, it should run pretty well. When the Adobe products become universal they should fly. I currently run all the same software plus Maya on my iMac G5 2.1 GHZ w/o a problem, so they should run just as well on the intel (more so when all apps become universal). I actually plan on selling the G5 and picking up the intel version so I can run boot camp and 3D Max as as well.

Imac intel core duo random shutdown

My iMac 2006 (late) intel core duo 2ghz shuts down regularly after brief periods of activity. As soon as I turn it on, the HD fan spins at around 5000rpm according to istat pro. All other fan speeds and temperatures are normal.I need to unplug it for at least an hour in order to successfully boot up again, an then the same thing happens over again. A new HD was recently installed with the Mac OS extended (journaled) scheme on , and someone mentioned it should have been as GUID scheme. Can that be a possible culprit ? I dusted it all out, changed the ram for new and even changed the power cord.

it should have been as GUID scheme
Yes - any Intel Mac needs to be GUID partition scheme in order to be bootable. So, if yours boots up without a problem, then it should be ok. Check Disk Utility (Applications > Utilities).
What OS version are you running? I'd suggest booting from your disks (not knowing which version I can't be specific - but one should have AHT (Apple Hardware Test) included. See these instructions on how to run it (use the extended test) and post any messages or results you get:

Anyone provide accurate info on why after 1 yr, after guarantee period expiry the DVD player on our I mac running Intel core duo processor with OS 10.6.8 refuses to run DVDs? CDs run

Can anyone provide accurate info on why after 1 yr, ( just after guarantee period expiry) the DVD player on our I mac running Intel core duo processor with OS 10.6.8 refuses to run DVDs?
CDs run without problem and until recently the DVD we have (all original no pirated copies) ran; we have used a CD cleaner disc to no avail.

Welcome to the Apple boards:
I suggest an erase and install and use your backup for any important files you have.
Did you perform a disk check/repair and permissions repair and a PRAM zap before updating? While not required, they are usually necessary to avoid issues.
There are so many reasons for a bad install, that it is impossible to list them all.
Out-of-date software, drivers, etc, haxies, and other software can cause problems.
My three updates were without incident, so it is possible for a perfect update, but unless you supply us with details about your previous system, programs, apps, drivers, etc., it is not possible to figure out what happened.
Again, whenever installing an update to an OS, a clone or other full backup is absolutely necessary, as reading the posts on this board indicate.

My computer is a MacBook Pro Intel core duo, and I need to know if I can run the new Lion OS?

My computer is a MacBook Pro Intel core duo, and I need to know if I can run the new Lion OS? The Apple web says must have Intel Core 2 Duo. Please advise. Not knowledgeable enough to know if not having the 2 between Core and Duo is a stopper. Appreciate any guidance.

The difference between a Core Duo and a Core 2 Duo is a show stopper when it comes to running Lion. The Core Duo is still only a 32 bit chip, but the Core 2 Duo is a 64 bit chip. You need the 64 bit chip to run Lion.

HT1338 I'm trying to upgrade to the OS X lion, and it says I need to have a Intel Core 2 duo. I currently have a 2 GHz Intel Core Duo. How do I go about making the change? Any help would be appreciated, Thanks Kevin
