2008 iMac + nVidia 8800gs + 10.5.3 - Any improvement with Aperture?

Can anyone with the latest 24" iMac (either the 2.8 or the 3.06 model) give any indication of whether the latest OS X update has improved the performance of Aperture relative to the Radeon 2600HD?
Given that barefeats has undertaken a number of tests with the latest OS X update and found some measurable performance gains for Pro apps I was wondering how this translated in the real world.
Are these improvements noticeable? Does Aperture still get bogged down and under what circumstances?
If the update provides enough of a performance improvement for Aperture (over the Radeon 2600HD) then I will order a 24" iMac with the 8800gs card because I also have a Dell 2407WFP that I want to use with it for viewing/editing images and use the iMac screen for placing the HUD and well, basically everything else.
Regards,
Jason

Yes, people have posted to this board that they've noticed significant improvement with the 8800 and Aperture. The sliders are much smoother now, with no more stuttering and choppiness.

I have a 2008 iMac 21.5" 10.6.8 Snow Leopard with 4.1.3 VMWare and windows 7.Mountain Lion initially refused to down load as I had back up on the HD. this was removed and installation was accepted but froze in the initial stages with 33 mins to go.

I have a 2008 iMac 21.5" using 10.6.8 Snow Leopard with VM Ware 4.1.3 supporting Windows 7. Initially ML OSX refused to install due to Back up on HD which I removed to trash.It then proceeded but froze up in the initial stages with 33 mins remaining. I was lucky enough to quit and restart using 10.6.8. With all the problems on this chat line, it appears it may be best to leave Mountain Lion well alone, and cut losses rather than tempt fate.Has anybody anything positive to say or help with?

Delay after reboot: any improvements with the new BT Keyboard and mouse?

Hello all!
I currently have the "old" BT Apple Keyboard connected to a one year old iMac. And of cause it suffers the delay after a reboot or awake of sleep mode. Sometimes it just takes forever till BT Mouse and Keyboard is recognized by the iMac.
Now as I am close to purchase a new iMac, I was wondering whether this mess is somehow fixed.
So, all who already have a new aluminium iMac and a Bluetooth keyboard - is it worth spending the money or will I still find myself in front of the MAC OS X clicking and typing and being full of hope that I finally can start working?
Thx for your experience on that!

Any luck with Aperture under Leopard problems. Here's the problem I'm havin

So, I can tell you that Apple knows of this problem. Two days ago I begun a thread that was a "roll call" for all those having problems with this app under Leopard.
Apple sent me a custom email back saying they had to remove the thread because it would be better to have seperate indiv's with their specific problems.
Ok, I buy that. But I know they are well aware of this problem. Not one mention of what they are trying to do to fix this. I have about 95 pct of my work in Aperture library and the Aperture vault. I will not use the other product from Adobe because, I paid for Aperture, I paid for Leopard and I really don't see why I have to purchase another product to do the work I've already paid for.
Anywho, my problem is still the crashing of Aperture not only when exporting but just randomly at anytime. I've kept Aperture closed not because it just is not worth my time to open the app at all. What a shame. I'm such a huge Apple advocate but now......
Why not at least a open letter from the Sr. Project Manager Joe Schoor? Anthing?
Has anyone found a sure fire fix for these issues? Thus far, I've tried to rebuild the Library, Re-install 1.5 and then upgrade online to 1.5.6 etc....

hi, tom
what are you running Aperture on?
when you reinstalled Aperture did you delete the Aperture folder in the applications folder and also the Aperture preferences, presets, caches files tucked away in the Home>Library and OSX>Library? if an application is misbehaving and you reinstall it but not remove all of it's files it may continue to misbehave.
I'm not an advocate of deleting Preference files and reinstalling but I might consider deleting the following files if I were in your shoes:
1. User\Library\Preferences\com.apple.Aperture.plist
2. Home>Library>Caches>Aperture - (Delete entire folder)
Maybe even the following:
3. Home>Library>Application Support>Aperture - (Delete entire folder. This will get rid of your presets and keywords)
4. Main Hard Drive>Library>Application Support>ProApps>Aperture System ID - (this will delete your serial number and you'll have to re-enter it).)
if any of the above files were corrupt the problem will be solved on start up or reinstall.

Is there any way windows 8.1 can be installed on an early 2008 iMac?

     Hello apple community! I've had various desktop maps since the mid-90's, but over the past 6 years I have found myself limited many times due to my computer being incompatible with many third party programs and various games that are only supported by windows. Therefore, I have finally gone out and purchased windows 8.1 from my local best buy to be run alongside Yosemite. I brought in all of my computer specifications and was told that I would be able to run the operating system.
The minimum requirements are as follows:
Processor: 1 gigahertz (GHz) or faster with support for PAE, NX, and SSE2
RAM: 1 gigabyte (GB) (32-bit) or 2 GB (64-bit)
Hard disk space: 16 GB (32-bit) or 20 GB (64-bit)
Graphics card: Microsoft DirectX 9 graphics device with WDDM driver
My specs are as follows:
iMac (20-inch, Early 2008)
OS X Yosemite (Version 10.10)
Processor: 2.66 GHz Intel Core 2 Duo
RAM: 4 GB 800 MHz DDR2 SDRAM (just updated)
Hard disk space: 332.3 GB free of 639.28 GB (plus a new 1 TB external drive that is in the process of being filled)
Graphics: ATI Radeon HD 2600 Pro 256 MB
Apparently my computer can only run bootcamp 4 and not bootcamp 5. Therefore, windows 8 is not supported for it can only be installed with bootcamp 5.
Sources: 1.Boot Camp 4, OS X Lion and Mountain Lion: Frequently asked questions - Apple Support
               2. Boot Camp: System requirements for Microsoft Windows operating systems - Apple Support
However, I've read articles about people possibly getting past these limitations, but they don't exactly follow my issue and may be outdate. Such as, http://www.videograndpa.com/?p=2628. I've seen posts from people in the forms saying that they are running windows 8 on their early 2008 mac, but they are from over a year ago. I've also read that apple may have had support for these operating systems, but dropped them, but the links to this information were broken. Best Buy has agreed to let me return Windows 8.1, but only for store credit. That is not fair if it turns out that I can not install it operating system when I was told I could by their employee.
     So, in conclusion, I'm wondering if anyone knows if I can install Windows 8.1 on my iMac from early 2008 with Yosemite and if they could walk me through it or link me somewhere that can. Thank you for your time.

Don't use a virtual machine, it's kinda cpu intensive. You CAN install windows 8.1 on your 2008 iMac. I know this because just a couple weeks ago I installed an official windows 8.1 disk on my 2009 iMac. You do NOT need to use bootcamp for it although you WILL need the boot camp drivers. Just put the drivers onto a thumb drive. You will need to install them manually, it's really easy though, so don't get discouraged. The only thing you need bootcamp for is to download the drivers onto the thumb drive. You can also download drivers for bootcamp version 5 from the apple website.
Here is how you do it: Go to disk utility inside applications folder and then utilities folder. Add a second partition to your mac and format it as FAT32.
Put the windows disk in your computer and reboot your computer. Hold down the OPTION key and then choose the "windows" disk then hit enter. Follow the instructions.
In the beginning there will be a screen asking you to select which partition you want to install windows on, highlight it, and then click on "format" because it is then going to reformat the partition as NTFS. It only takes a second. Just follow the installation instructions, it's pretty straight forward from there. And just to forewarn you, apple doesn't care to update the drivers for SOUND, people with iMac's running windows don't have sound so you will need a third party sound card adapter with a headphone and microphone jack and use either headphones or an external speaker. I got a cheap one from ebay for just a few bucks. I use the "Syba" brand and it works, it even plays that pretty windows startup sound. All sounds work, even youtube.
Thank me later! By the way, I think you will find that windows 8.1 runs way faster and smoother than mavericks or yosemite. The mac os's have gotten pretty buggy and bloated over the years and so I think we are making a switch to windows at the right time. Everyone is saying how much better microsoft has gotten and I can tell. I have everything pretty much set up how I like it in my windows 8.1 partition and it's pretty fast. Also, it is WORTH IT to pay for the MacDrive software. Just google it. It will enable you to view and change any apple formatted disk/drive, including your mac osx partition on your internal hard drive. This is important for me because all of my music is on my mac partition in itunes and I need it to add music to my iPod classic 160gb but with macdrive I can listen to the music in vlc player or windows media player. I don't think I will install itunes on windows because everyone says the windows version is buggy.

Go to /Library/Preferences/System Configuration
Move all the files from the System Configuration folder to the Trash.
Restart your Mac. See if that made a difference.

What can I do about a 2008 iMac that does not accept any input, thus blocking entry of password at startup?

My 2008 iMac (20 inch) often freezes. Now it will not accept any input on startup. I type in my password, but it will not accept any characters I enter. The blinking line just continues to blink. It will not acknowledge my keyboard, mouse or trackpad. I have done a forced reboot and a force reboot combined with subsequently disconnecting the power cord and then restarting. No response from either step. What can I do?
Thanks.

Glad it is working for you.
Have a look at these two articles they may help if it occurs again.

You are only running on 2GB of RAM. IMHO 4GB woud be the minimum to realistically run Mavericks on, although the more the better.

My 2008 iMac will get to the white boot up screen and has the loading circle and then it will freeze. And will freeze when attempting to boot recovery or bootable disc of Mavericks

Hi there, I have a 2008 iMac 24' 3.06 Intel Duo with 4gb ram. And yesterday it was working totally fine and jolly with no issues. Then I noticed there was an OS X update for Mavericks, so I finally decided to do it, and once it was rebooted it went to like the grey screen and I could move my mouse, just nothing else was there. So I tried to restart it, and then it booted up, but was really laggy, and so I decided to restart it and try again, this time the iMac froze at the login. So I decided to take it apart, pull the 500gb hard drive, connect it to my MacBook Pro, and then formatted it in Disc Utility. From there, I opened the Mavericks installer on my MacBook and then installed it to the iMac's hard drive via usb hard drive enclosement. And once the install of Mavericks was completed, I put the hard drive back into the iMac and tried to boot it. It now boots up to the white screen with the Apple and the loading circle underneath the Apple and then it freezes and doesn't go any further. So then once that happened, I turned it off and tried to boot it into recovery mode. Then it freezes on the screen with the Apple and loading circle below it. Then out of desperation, tried to use a bootable disc of Mavericks to see if i can at least get the iMac to boot up again, with no success. It froze at the same point again. So now I reach out to the Apple Community to see if anyone else has an idea on what I can do or if anyone had this issue and what they did to resolve it. Any help would be great. Thanks.

mddcfilms and Pat75, I'm having precisely this same issue -- no booting but spinning and freezing gear under the Apple logo. Have either of you come to a resolution? Here are my details:
iMac, Early 2008, 24”, 3.06 GHz, 4GB
September 2013: Nvidia GeForce 8800 GS GPU repaired, HDD replaced with Western Digital 2TB
21 April 2014: Erased HDD with Disk Utility on Mavericks USB; clean installation of Mavericks from the USB. Process completed without issue, including registration process. After a minute or two of poking around, machine shut down immediately (not through the shut-down process).
Since then it will not boot up. Grey screen and Apple logo appear, with gear spinning; the gear freezes, then the machine tries to boot up again. Occasionally I’ll hear “To use English for the main language, press the return key.”
I’ve tried booting into Safe Mode; same gear freeze and restart.
I’ve tried booting to the 10.9 Recovery disk; same gear freeze and restart.
Tried booting from Mavericks USB; same freeze and restart.
Tried booting from 10.6.3 DVD; same freeze and restart.
Ran Apple Service Toolkit (at Stormfront in the UK), which turned up nothing in error.
Started in single-user mode to test HDD and RAM, which are fine.
Started in verbose mode to check logs; some error messages but nothing seems crucial. After the log screen, the grey screen and Apple logo appear, gear spins, and then freeze.
Cannot get to Apple Hardware Test (vintage machine too old?)
Cannot get to Target Disk Mode with my MacBook Pro
Ideas: Potential booting flaw in Mavericks installation. Firmware incompatibility with Mavericks. Hardware issue in Nvidia GPU (known for problems). At the moment I'm hoping that it's a Mavericks installation or firmware issue, though I suspect the Nvidia GPU has blown up on me. These graphics cards are known for being pieces of junk, so I may try installing the lower spec ATI Radeon 2600 GPU if I can find one at a reasonable price.
Anybody else have precisely these problems or have any advice?

Is there a modern replacement for the Nvidia 8800GS?

Like other imac users my imac 24" (2008) Nvidia 8800GS graphics card has just stopped working, I'm wondering if there is a modern replacement for this card rather than buying a (expensive) reconditioned one?

http://forums.macrumors.com/showthread.php?t=1440627
There is a lot of conflicting data on whether the graphics card in the imac is replaceable. This stems from the fact that many of the older generation imacs have the GPU soldered to the logic board. This is NOT the case with the 2008 24 inch that has the card mentioned above. It is very difficult to get to. But with planning, patience and care, it can be replaced.

2008 iMac and Snow Leopard

My parents bought a new 20 in iMac this February with a ATI Radeon HD 2600 Pro Graphics Card. It was their first Mac previously having used PC's. I was looking at the Snow Leopard specs last night, as they will ask whether they should get it and it clearly says that Open CL will only work with the ATI Radeon 4850, Radeon 4870 or more recent NVIDIA cards used in the iMacs introduced this year.
I was a bit shocked at this, surely there must be some mistake. OK my 5 year old G5 won't run Leopard, but to find that a six month old iMac won't run a core Leopard component is, well, not very impressive. So Leopard will boost your Mac's performance but only if you bought it this year. I have to admit I'm beginning to wonder about Apple.
Can anyone tell me whether Snow Leopard will boost performance on this iMac at all?

OpenCL is not a "core" Mac OS X component. All it does is allows developers to use a Mac's graphics hardware (the GPU) to do some non-graphics processing in certain situations, basically off-loading some types of work from the CPU. But the primary purpose of the GPU is to accelerate graphics processing, and Snow Leopard supports the OpenGL every bit as well as Leopard. Also, to take advantage of OpenCL, developers have to figure out where they can apply it, and recode their applications to use this new capability. That's going to take time.
Therefore, Snow Leopard will immediately make your parent's iMac run better, more efficiently, in many ways not related to OpenCL, due to the different areas of optimization. Lack of support for OpenCL does not make that iMac any slower when upgraded to Snow Leopard, it just just a non-factor, something that does not apply. There will be no impact from OpenCL even on supported Macs until developers learn how to use this capability and update their apps.
It is the same as any improvement Apple makes from one generation of iMac to the next. The 2008 iMac supports 4GB of RAM (officially), the 2009 iMac supports 8GB of RAM. The 2008 iMac can connect a 24-inch second display, the 2009 iMac can connect a 30-inch second display. The 2009 iMac has larger hard drive storage options. And so on...

Display crashed - 2008 iMac running Windows 7

Hi there,
I have a later 2008 iMac running Windows 7 on an Nvidia 8800gt. I've been using the Windows side only for playing games, and have been doing so for about a year now. Everything has worked fine until today running Far Cry 2. The display started to stutter, then froze up. I rebooted, and it did this again, eventually crashing out of Windows.
Long story short, when I turn the iMac on now the grey screen is covered in green pixelated lines, and it won't show anything else. Did I finally kill the graphics card, or do I have bigger issues?
Any help is greatly appreciated.

Hmm...looks like you've been bitten by the "weak NVIDIA chip die" issue that so far has not been confirmed in desktops.
During the NVIDIA chip scandal of 2006-2008, an investigation was launched (media source I can't recall) which found a fair number of GeForce 8/9 chips also fell to the same supplier's mistake that crippled countless notebooks.
The best you can do is to bring the unit over to your local Apple Authorized gurus (including Apple Stores) and have them check it out. You can tell them that you suspect a bad GPU. I'm not sure if you'll have to pay for it, though if you bought AppleCare, you'd still be covered today.

2008 iMac - Target Display Mode?

Hi! I am a little confused it looks like newer versions of the iMac 2009+ support target display mode but I can't find any info on older iMacs. I have a 2008 iMac that has a mini DVI on the back and a 2010 MacBook Pro with mini displayport. My question can I use the iMac as a monitor for my MacBook Pro? Can I take a mini displayport cable to DVI and a DVI to mini DVI to the back of the iMac? Or is the mini DVI on the back of the iMac an output only? If so does it allow you to use a second monitor?
Thanks!
Guy

I hear you - I'm trying to make it 4 (at a little over 3 right now) because I have some camera gear I want to buy first. My iMac has been crawling a bit lately especially when running Aperture. Just did a fresh Lion install this weekend and it seems to have improved. Was thinking about getting a super beefy Mac Mini and a 27" Cinema Display instead of an iMac next time - that way I can upgrade sooner and not feel so bad about it. Keep the Cinema Display and replace the Mac Mini every 3. Else bite the bullet and get a Mac Pro - but not sure I want a giant cheese grater

2008 iMac + nVidia 8800gs + 10.5.3 - Any improvement with Aperture?
