IMac iSight grainy

The image of my iSight is rather grainy.
The problem
The pictures produced by my iSight are quite grainy compared to a Macbook. They were both tested only 20cm or about 2/3th of a foot apart from each other. While the Macbook offers a reasonable image quality, the iMac image quality is subpar and resembles the quality of a very cheap 0.8MP camera.
Is there anything I can do to calibrate the iSight to offer a better quality or is this a known issue?

Hi there,
Unfortunately it will probably take a software updgrade to improve the iSight Photo Booth images. They are only 640 x 480 and even at this resolution the images are still of slightly poor quality. It is roughly only 1 megapixel and uses a plastic 'lens'...
I have found that using ALOT of natural light or plenty of incadescent light will improve the image. You can also improve the image in your choice of image editing software including iPhoto, but you can only improve so much...

I had to replace my hard drive in my iMac iSight and now I need to load an os all I have is my windows laptop any help?

I just had to replace the hard drive on my iMac iSight G5 and now I have no os and have no idea where my restore discs are i was wondering if I purchased an os from apple if there is a way I can load it onto dvd then load my iMac

You can contact Apple at 800-767-2775, give them your serial number (under the foot of your iMac) and they will, for a small fee, send you the install disc. Then buy a black retail OS from Apple or eBay.

Imac iSight external video adapter

My original display on the iMac iSight is damaged. I noticed the external video port and may I assume that I could use it to run it that way. But the problem is figuring which adapter to use. Somewhere is mentioned PN M9321 G/A and PN 9320 G/A but when I go to the store to purchase it it does not say that it is suitable for my PPC iMac. It does say that is suitable for intel I Mac. If anyone would please let me know what is to do.
Thanks in advance

After a search in two different directions, I found some information on what may be the correct VGA adapter for mirroring the internal display to an external; a page link and a product number. Appears to be obsoleted, but a call to Apple (main online store, or local Apple Store) should let you know if you'll be looking for used online, etc. Could be there is a new part number for this, or perhaps some authorized reseller has old stock? or a lucky find.
The adapter in question probably fit a few different models of that vintage, so someone online may have one if it truly is obsoleted. Some look similar but do not work the same.

Problems Viewing external Projector on Imac ISight

I have the new Imac iSight.
I was able to connect it to my HT using the apple DMI-Mini-DVI cable.
However the following day I turned the system on and my Imac is no longer recognizing my mini-dvi port.
I have checked System Profile and I don't see it listed.
No External displays are shown.
I have turned off and restarted all of the equipment in various combination, e.g.
computer-projector, or projector-computer etc..
Anyone knows how I can determine wether or not the problem is the port or something else.. ?
Thanks

Both iMac iSights Won't Start Up After Upgrading To 10.4.6

I just bought 2 iMac iSight's clearance from Mac Mall - with Applecare, but I can't use it until Mac Mall resets the serial numbers with Apple, who currently thinks they were bought in January, so no chat help. Ack! Downside to buying open stock clearance! Anyway, when setting them up, I let them upgrade to 10.4.6. They did the first reboot, then totally froze on the second. Both of them, exactly the same. And I don't have the right Torx driver to do the internal reset. What happened to the flat head screws on earlier iMacs? I tried the power cord in and out with the power button depressed trick. Nada. Help, I have new employees coming in tomorrow expecting computers to sit at. TIA,
Fred

<<If you look at MacInTouch, you will find reams of complaints about MacMall. You have to be very firm with them, and threaten all kinds of dire things.>>
I'm sure they're all criminals, but I have one salesperson who cuts me some deals, so sucker that I am I go back. I once had a G4 problem with a defective RAM slot - inserting the stick bent the contacts both sides across the middle, and I was going to be stuck for a new m-board on a machine that had only booted once, and they weren't very nice to me about it, until by chance they noticed the same thing in other machines of similar serial number. With their testimony, Apple gave me a "one time only" repair on it - how very generous of them.
Back to current problem, and thanks all for the help - power cable manipulation has gotten one of the two to boot up normally, thank god, and the other is being slightly more responsive (rapid manipulation of power button makes front panel LED and mouse LED light up momentarily), but hasn't booted yet.

Help opening a G5 iMac Isight

I have a G5 iMac Isight (17 inch), whose hard disk has died.
Since I have worked on many Mac's, I was going to replace the HD myself. However, I cannot figure out how to open the case.
I followed the instructions for the original iMac, but apparently the iSight is different - doesn't have the same screws. I cannot find a manual online to open up the computer.
Any suggestions would be appreciated.
thanks,
Ron

How MUCH heat is acceptable coming from iMac/iSight?

My week-old iMac/iSight is getting very hot in the upper lefthand corner of the screen. Sometimes it's almost too hot to touch.
I've talked with several Apple Techs and went through the usual hardware tests. Nothing was found.
But eventually this much heat is going to do further damage to either the screen or other hardware. Being only a week old...shouldn't they just replace it if they can't determine the problem? I don't want to be stuck with a machine that melts down in a week or month and then end up in the repair shop time after time.
iMac/iSight Mac OS X (10.4)

QGrayson:
On the iSight, the processor is in about the upper left quadrant as you face the computer. That seems to be where most of the heat is generated. When you feel the back of the computer case, it will be warmer than else where. It also seems to be warmer where the Apple emblem is on the front. There is an exhaust vent-really slits-that goes across the back at the top. The exhaust air coming out of the left back is warmer than from the right back. Mine has never been hot. Warm yes but never hot. Also, when I touch the bottom where the grill goes across the computer, it seems cool there. At least with my computer.
Regarding temperature sensors. Whenever I give values I add that I am using the processor at the highest and the screen is the brightest. People give temperatures but do not specify strength processor is being run or brightness of the screen. These do affect the temperature sensors.
Using Hardware Monitor, mine are as follows:
ODD 104.9, HD 112.1, NB Amb. 140.9, NB 164.3, GPU Amb. 133.0, GPU 130.6, Incoming air 86.9, CPU 129.6. CPU current is 1.74.
These are the numbers right now. I have Firefox, Safari and Hardware open. The room temperature is no where near 86.9. I can only assume this sensor is not really measuring room temperature which is about 68-70 as per thermostat.
I don't think my number are high or go higher. They have been lower. Also, my fan speeds do not vary very much.
This only confirms to me the iSight runs at a lower temperatures the the earlier models.

IMac (iSight) Manual Available

Hey everyone. The new iMac's manual is now available for download. Althought I imagine most of us will elect for the Rev C description, its technical name is "iMac-iSight."
So, we have:
iMac G5 ("Rev A")
iMac G5 ALS ("Rev B")
iMac G5-iSight ("Rev C")
Enjoy!

You're right, but I think several people use the "Rev" terminology in reference to their G5 iMacs (I've done it myself, even though I knew it wasn't technically correct). As long as people use the iMac G5 descriptor, it will be clear. Personally, I will opt for "original iMac G5," "iMac G5 ALS," and "iMac G5-iSight" so there's no confusion.

IMac iSight GPU Temp?

Hi,
I just got my iMac iSight a couple days ago, and i was monitoring the temp of the iMac with Temperature Monitor when i noticed that sometimes my GPU Temp will go up to around 96°C/205°F ... is that normal? i dont want to burn up my graphic card... thanks in advance for any help on this..

Valhalla:
Are you referring to you CPU temperature or the GPU because there are two GPU temperature sensors. I assume you mean the CPU. I don't care what you were told. To me 205 is too hot. Noone else has reported a temperature that high. In fact, I believe the earlier versions shut down around 180+. Why should this one be able to go up to over 200?
I would call help desk again find out what is the accepted range, tell them you think it is running to hot and a new computer or any computer should run that hot. Better yet, find out at what temperature the computer shuts down. Get a case number and make sure you tell the individual that you fear it will burn up your graphic card.
Or tell Apple you are returning the computer. I would be very tempted to return it and don't fret about how long it would take to get another.

Final Cut Studio 2 on iMac (iSight)

Hi,
I'm currently a beginning film editing student and able to get FCS 2 on student discount. My current computer is the iMac isight version (purchased 2 months before the intel release!) The computer is pretty fast with photoshop apps. Does anyone know if I will be able to run FCS 2 for work on small projects and for learning purposes. The most I'll be editing would be SD and small HD clips for projects of no more than 5 minutes in length. My graphics card (ATI Radeon X600 Pro) is not mentioned in the requirements for FCS 2. Any help would be appreciated.

All the applications should run, but you will probably get slow performance from Motion 3 and Color.

Upgrading Hard Disk iMac iSight

ALCON,
I bought a WD 500GB SATA drive yesterday and then spent a few hours yesterday ignoring Apple's caution about the only user upgradable part inside an iMac iSight G5 being the RAM. In short, they're right. After (eventually) opening the computer and getting under the screen to reveal the hard disk, there was no way to remove it without disassembling a whole lot more than I wanted because you can't get a screw driver/torz bit onto all of the screws holding the drive in without disassembling all kinds of stuff. Furthermore, getting to this point required me to tear open the protective lining inside the computer and I ended up pulling the isight mic wires loose from the top of the case. Last, even if you get further than I did, you'll have to contend with how to remove and hook up the temperature sender connected to the side of the OEM drive. The WD I bought does not appear to have the correct connection to make this work. So, hours later I successfully reassembled my iMac and it works fine...minus the mic. I took a couple of pictures for anyone interested. Send me an email to [email protected]
Jeff

Hello Jeff,
I bought a Seagate 160GB SATA hard drive, and looking to the installation instructions it seems that the drive does not have the screws holes and connectors located like in the instructions PDF manuel that I got from Apple. It seems so simple in the instructions ...
Where can I have a look at your pictures ??
Thanks in advance.

G5 iMac iSight Keeps Crashing

My G5 iMac iSight keeps going to the dark vail while running or rebooting and gives me the message that I must reboot. This has been going for months now. It will be stable for a week or two and then do it over and over again. These last episodes were kicked off by me loading iLife '09 on it. After that it couldn't make it back from the rebooting. I had to do an active and install to get it back and running. Then it occurred over and over again during the update to 10.5.7 restart. It seemed okay for the last couple of days, then it did it again last night and then just couldn't restart from there. I've tried resetting the PRAM, removing USB items, repairing the drive from the OS X disk and now it get it started this morning I removed the 1gb extended mag stick and disconnected FireWire drives with a successful reboot.
What am I missing? What else can I try? Three other macs on the the network are working fine. This one I use as a media server so I need the extra drives and all the USB stuff.
Thanks!!!!

It may be that your RAM is faulty, that is often the cause of kernel panics, which is what you have been having. Try the solutions in Dr Smoke's Resolving Kernel Panics and see if any of them helps. But look to your memory first, and use Rember to check it.

Upgrade imac isight 5

Can I upgrade the OS on imac isight 5 (2005) with version 10.4.11 to a later OS (maybe Mavericks)? And how to do this? I just had the imac repaired (internal power was broken and there was no start-up) and would like to update to the most recent/latest system possible on this older imac.

The maximum system you can install on that model is Leopard 10.5.8. However, it is not offered by Apple at the Apple store. Only Snow Leopard, Lion and Mt. Lion are currently offered.

I went up to the Apple store tonight to buy the iLife '06, and while I was there, I thought I would run some benchmarks on the Quad G5 PowerMac. While doing that, an Apple guy started talking to me and mentioned that they had 3 iMac intel machines that they just set up today. Perfect - I was running video benchmarks anyway, I would just go over and run them on the new iMac. Here are the results (including some tests I did for a Mac Mini article a few months back):

Overall, I was disappointed with the iMac duo performance. When I first walked up to the machine and started using it, it felt sluggish right away. Of course, I had just walked from the quad, but still, the apps lagged for a second when they were launched, dashboard stuttered when I first hit it, and I got the beach ball a few times right away when launching iMovie, the clock and activty monitor. Actually, it felt clunky and more like being on a PC the way that it seemed to hesitate for just a moment when doing things. But I was the most disappointed with the render speeds, which were only slightly faster than single processor iMac G5 1.8 Ghz on most test, and half the speed on anything with h264. The h264 export result was so suprising that I tried it a couple of different times with a few different setting, all with the same result - all very slow - about half the speed of the iMac G5. Could this be a case of much of the code still not being optimized for the intel?
Another thing that is still baffling me is the processing CPU % utilized on the PowerMac Quad G5 during rendering. It is still not getting up above 25% to 35% when rendering in iMovie or iDVD. When I exported from iMovie to h264, it took 59 seconds for a 1 minute clip (1000 kbit/s, 720 x 480, 30 fps), and the processor went up to 55%. Of course, all of these test are iMovie and iDVD. I did do a test exporting from Final Cut on the quad, and it was actually slower than iMovie. It took 90 seconds with the processor running at 40%. I guess that I am still baffled what the benefit is of having all the quad power processing sitting there if it is not going to get used the most when you need it - during heavy duty rendering. For that performance, it seems I would be much better of just getting the dual G5 PowerMac, because it gives similar rendering performance as the Quad, but at a far less cost!

This is really upsetting because I am really anal when it comes to people messing with my stuff. Please help.
