IMac 2.8 Ghz, Intel Corei5 with 8gb of ram takes 5 minutes to start up! why so slow???

I ran MacKeeper yesterday to see if I had problems with something, it cleaned up a lot of stuff, but still, this morning it took 5 minutes to start up!

MacKeeper is malware and may the reason for your problems. No maintenance software of any type is needed for OS X, it will maintain itself! OS X is NOT MS Windows and does not require a lot of user intervention to run smoothly. Following Apple's instructions in your owners manual is your best bet!
Please follow the developers instructions for removing MacKeeper immediately!!!!!!!
To solve your startup issues first check System Preferences - Users & Groups - Login Items and remove applications and files that are not needed on startup.
Also if you are running Lion or later (10.7.x) then quit applications prior to shutdown and/or follow the onscreen directions when shutting down. Also please carefully read your owners manual about shutting down your system, Apple recommends putting the system to sleep.
Finally please complete your profile, attempting to help someone when we don't know anything about their system is difficult at best. If you don't know how please click Profile Update for instructions.

Why is my iMac (2.8.GHz Intel Core i7 w/ 4GBs RAM) using so much RAM?

Right now I have only Firefox open with 4 tabs. Firefox only has 1 extension (1Password). No other application open or running (that I know of). My dock has 17 icons (including basics like trash, finder, launch, etc). As mentioned I have a:
2.8 GHz
Intel Core i7
4 GBs RAM
21.5 Inch
Running on 10.7.3 (Lion)
My RAM situation is this:
1.83 GB Free
78 MB Inactive
1.40 GB Active
697 MB Wired
2.17 GB Used
4.0 GB Total
Image of my Activity Monitor (with user removed) here:
columns as follows: PID, Process Name, % CPU, Threads, Real Mem, Kind
I'm trying to figure out why my iMac is using so much RAM when I only have Firefox open? are any of these activities unnecessary and if so how might I turn them off and so they don't start automatically when I initially turn on the computer? This imac is two weeks old and so I haven't done a whole lot of customization yet. Please help if you can. Really appreciate it. Trying to optimize this baby. Thank you!!

Here's mine: I have 16 Safari tabs open, some with Flash junk, and 13 apps "open" according to the Dock indicator:
By the way the number of icons in your Dock has essentially no effect on memory. Only running apps - the ones with the little dot indicator - might be occupying memory. Even that is somewhat of an oversimplification, since "active" apps may or may not have any active processes associated with them. It's all a function of how Lion manages its memory resources, and that is a whole new world to most of us.
With Lion, Apple is seeking to eliminate the system effects of whether an app is even open or not. Just another trivial detail the average user ought not to be concerned with, in their opinion.
If you want a cursory introduction to that fascinating subject, Google the Ars Technica Lion review that was written a few months ago. It may ease your concerns about memory management. If you are an experienced computer user, it will rock your world.

I'm thinking about purchasing a 21.5" iMac. The base model comes with 8GB of RAM, and the RAM is not user-upgradeable down the road. Is 8GB enough memory or should I upgrade to 16GB?

I'm thinking about getting a 21.5" iMac which comes with 8GB of RAM. Unfortunately, the RAM is not user-upgradeable. Do you think 8GB is enough memory, or should I upgrade to 16GB? Besides internet surfing and email, I like to play flash games and listen to internet radio. Occasionally, I might want to stream a movie. I would greatly appreciate any advice you could give me.

For what you list, 8GB should be adequate. I ran with 4GB without any issue for over a year in my iMac i7 before I added RAM, primarily for running Win 7 via Bootcamp.
The tasks that need a lot of RAM are typically video editing/production, heavy-duty photo manipulation (not iPhoto or PS Elements), and professional page layout like Adobe Creative Suite. If you think that, down the road, you may want to delve into those fileds with this computer, by all means get the extra RAM.
I like to play flash games
I didn't try a lot of Flash games while I still had 4GB RAM but those I tried ran without issue and without causing a non-trivial number of page-outs

3.6 GHz Intel Core i5, 8GB 1333MHz DDR3, 2TB FREEZES UP FROM DAY 1

I have a new imac 3.6 GHz Intel Core i5, 8GB 1333MHz DDR3, 2TB
Its been freezing since the day I've bought it. $2300 dollars down the drain.
I'm trying to edit with FCP but I never get very far. I called Apple support twice. Did the usual Pram, and pull out the plug and hold the button in for 5 seconds, when through the disk repair options, installed the OS. I'm afraid to call again, because i know their going to tell me to erase the disk. I also know thats not the problem, and its going to take a long time to reload everything. I have a MacBook i7, and a PowerMac which I also edit on, and there both solid. I'm an editor by trade.
So I just made a new account, attached a HD with footage on it, (I'm editing the same project on my Macbook, works great). Opened the project started to edit, 5 minutes in. Freeze... and the loud noise.
Been reading other posts... looks like this problem been going on for years.
Has anyone ever fixed this problem?????
Soon I will be boxing up the iMac and sending it back.
I've been editing on Mac's for 20 years.
I've never seen a Mac that really just does not work... this is it.
Its called the iMac. (also my iphone 3s died after a year)
Maybe Apple is getting too big.
Update: Packing it up and taking it back. I believe the Apple RAM is the problem. Lets see if the "Geniuses" can figure it out. I'm not holding my breath. When I brought my dead iphone 3S to the "Geniuses". They ran the same tests i did, had to wait around for a few hours to be told what i already knew. It was a dead. Listen, I Iove Apple, its so depressing, but I believe Apple knows theres a problem with the RAM on these computers. Too many people are having problems. Unlike Toyota, who pays for their faults.... Apple just gets away with it.

Update Just got my iMac back for the second time.
Again Apple has said there's nothing wrong with the computer.
Apple erased the hard drive.
I just tried to upload Time Machine... it froze.
Tried it again, it worked, got everything back.
Then wanted to update software.
Downloaded updated software, then when it rebooted and started to install, it froze.
Did it again.. it froze.
Now just bringing in the updated OS, it worked, rebooted.
Went to Safari... it froze.
Why doesn't the computer freeze when Apple has it?
Is Apple lying?

IMac CPU3.06 GHz Intel Core 2 Duo, 8GB, Extremely slow and repeatedly "out of Memory" since migration from Mountain Lion to Mavericks

Dear Apple Support Community.
As mentioned by a number of users reporting the same problem, my 2009 iMac CPU3.06 GHz Intel Core 2 Duo, 8GB RAM, has become extremely slow and repeatedly "out of Memory" since it was migrated from Mountain Lion to Mavericks (OS 10.9 then OS 10.9.1).
I have already run CleanMyMac, deleted 5GB of useless stuffs, which did not translate into any improvement. Following the advices collected in other Apple Support Community threads, I have applied EtreCheck the outcome of which is provided below.
For information, I have also upgraded my 2011 MacBook CPU2.3 GHz Core i7, 8GB which became only a bit slower than before, sometimes freezing which it almost never did before. However, I am used to the fact that Mac get usually slower and more prompt fo freeze after upgrading to a more recent OS.
Both my 2009 iMac and my 2011 MacBook have F-Secure installed. So the problem with the 2009 IMac is unlikly to be due to the presence of F-Secure. Interestingly, the few abnormalities found by Etrecheck were exacly identical before I ran CleanMyMac. There are two more findings (mentioned below) since I ran CleanMyMac on the 2009 iMac, which again didn't improve the problem.
So please find below the details of the EtreCheck experience and some additional measurements made with iStat while running EtreCheck:

Please find now some additional measurements collected with iStat while running EtreCheck:
Practically:
The iMac can work slowly with only one software e.g. either Mail or Safari or Firefox, but still the below "out of Memory" message occurs about every 3 minutes.
Aperture has becomre to slow to be useable
If trying to write a mail (with Mail) while Safari or Firefox is open, then the "out of Memory" message occurs about every 20 seconds so I need to check on "Resume" several times per minute.
Conclusions
From the above, unless anyone in the Apple Support Community proves to be able to identify a specific problem leading to a way to find a cure, I tend to conclude that Mavericks is not suitable for computers operating with a Core 2 Duo CPU even with a 8GB of RAM.
Unless I missed something, I did not see any warning from Apple Computer Inc. informing their customers they should refrain from upgrading Core 2 Duo Computers.
The only solution I see so far is to downgrade from Mavericks to Mountain Lion. And the Apple Support Community would confirm that it is the only solution, I would appreciate to get your guidance on how to proceed.
Intended action plan
Migrate the above 2009 iMac to a 2014 Mac Mini Server operating on Mavericks to ensure that no data may be lost while downgrading to Montain Lion.
Provided the above downgrading operation is successful, assign this 2009 iMac to partial retirement e.g. Mail, Skype, iTunes and DVD player.
In advance, I would like to thank the Apple Community for helping me either i) finding a cure to the problem, ii) or confirming that Mavericks cannot operate properly on Core 2 Duo computers, iii) and in such a case, guiding me on how to downgrade to Mountain Lion.
Yours sincerely
Core

... what anti-virus would you recommend using?
Use what is already included with OS X. It already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple.
A much better question is "how should I protect my Mac":
Never install any product that claims to "speed up", "clean up", "optimize", or "accelerate" your Mac. Without exception, they will do the opposite.
Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources. Illegally obtained software is almost certain to contain malware.
Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iTunes or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Don’t install Java unless you are certain that you need it:
Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
Disable Java in Safari > Preferences > Security.
Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
Block browser popups: Safari menu > Preferences > Security > and check "Block popup windows":
Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore it.
Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
The most serious threat to your data security is phishing. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.

Running Mavericks on an iMac 2.7 GHz Intel Core i5, I've been trying to install Adobe CS3. All components install except InDesign. Is this an installation disk problem or is it not compatible with the OS?

Running Mavericks on an iMac 2.7 GHz Intel Core i5, I've been trying to install Adobe CS3 Design Premium. All components install except InDesign. Is this an installation disk problem, or is there a compatibility problem with the OS?

I fear that you are trying to download OLDER Software on a newer Operating Sysytem Meaning that you need to Install the Latest Version of Adobe on the Newer Operating System for it to work Properly. Be sure to always check the minimum System Requirements.

IMac 3.06 GHz Intel Core 2 Duo with 12gb of RAM running very very slow.

My late 2010 iMac 3.06 GHz Intel Core 2 Duo with 12gb of ram is running very slow. It takes a very long for the computer to boot with the desktop taking ages to fully load. Applications are also taking an unholy amount of time to load with the spinning wheel always appearing through out use, and they often crash or don't respond and close during use. I'm talking applications like Word taking 3 minutes to load and getting the spinning wheel when font size is tried to be changed and crashing and closing if a large volume of text is attempted to be pasted into a document.The computer is also failing to shut down properly just staying on a blue screen. I recently wiped and completed a fresh install however the issues came back.
As you can imagine after spending so much on the computer I'm not best pleased about these issue, I've spoken to the apple staff in my local store by they weren't very helpful and seemed to no little about computers and the so called "Genius" who I spoke to about my issue was a joke, repeating himself and talking utter rubbish, while I understand you need to look at a computer to get a real picture of an issue, some advice could of been provided. I haven't got time to take the computer to the store at the moment and get a technician to look a it, so I was wondering if anyone else had experienced these issues and knew what caused the fault, and that way if possible I can repair the issue myself.
Thanks in advance for any help on the issue it’s much appreciated. At the moment I'm pretty close to ditching the thing and buying an Alienware!

Imac 2.16 GHz Intel Core 2 Duo with 2 GBs enough?

Before I drop 5 bills of Logic 8, what kind of performance am I looking at with a Imac 2.16 GHz Intel Core 2 Duo with 2 gigs?

Your machine is a whole bunch faster than the G5's most of us use, and 2 gigs should be fine. The only way you'll get a benefit from more than 2 gigs of ram is if you use other programs alongside Logic, or if you use lots of large EXS samples. Additional ram beyond 2 gig will not get you greater track count, more Space Designers (or any other plugins besides EXS) or lower latency. It will not get more instances or sample sizes for third party plugs used as AU within Logic. If you run third party plugs as rewire or standalone - separate from Logic - they will benefit from additional ram.
I'm doing very well with a G5; additional drives and pci interface help alot. You should do even better with an Imac, although I don't know if it has a PCI slot.

Freeing Up Space on The Hard Drive
1. See Lion/Mountain Lion/Mavericks' Storage Display.
2. You can remove data from your Home folder except for the /Home/Library/ folder.
3. Visit The XLab FAQs and read the FAQ on freeing up space on your hard drive.
4. Get an external hard drive on which to store some of your files after which you can
      erase the data from your internal drive to free up space.
5. Also see Freeing space on your Mac OS X startup disk.
6. See Where did my Disk Space go?.
7. See The Storage Display.
You must Empty the Trash in order to recover the space they occupied on the hard drive.
You should consider replacing the drive with a larger one. Check out OWC for drives, tutorials, and toolkits.
Try using OmniDiskSweeper 1.8 or GrandPerspective to search your drive for large files and where they are located.

Late 2006, 24" iMac, 2.16 GHz Intel Core 2 Duo, Screen Tearing, nVidia 7300

Late 2006, 24" iMac, 2.16 GHz Intel Core 2 Duo, Screen Tearing, nVidia GeForce 7300 GT
I've been suffering with screen tearing, strange screen artifacts, etc. followed by totally unresponsive freezing machine. This problem has been happening to varying degrees for about 9 months.
Initially, I was able to mitigate the problem with smcFanControl. Adjusting the fan speeds up helped keep the machine cool and prevent most of the problems. Recently, we had a spell of hot weather and the fans just couldn't keep up. If you're using smcFanControl, the only fan speed that will really make a difference is the CPU. The HDD and ODD fans are no where near where you need to be.
Also, I noticed the machine was LOADED with dust when I took it apart, including the heat sink fins for the graphics card. If you have time you may want to try a thorough cleaning with compressed air before replacing the card. You just need to get through step 11 below to access what needs to be cleaned.
Based on reading here and elsewhere, I decided to replace the graphics card. To give back to the community, I wanted to layout the procedure here.
Where to buy the card.
I had a tough time finding the right card. I did exhaustive web searches using every combination of Nvidia 7300 GT, etc. You really need to search by the Apple part number. The Apple part number for the 7300 is 661-4179, for the 7600 is 661-4180. I found it at We Love Macs and at dv warehouse. I paid $248 for the 7600 card. BE CAREFUL buying a "refurbished" card. At We Love Macs, "refurbished" means "pulled from a working machine." Could be a machine with as much mileage as yours and prone to the same failures as yours.
The card is an MXM style card (generally used in laptops), with a giant heat sink and heat pipe assembly. The card can be separated from the heat assembly. If I had time, I would have tried a generic, cheaper, MXM style card.
Dispelling some myths.
People here and elsewhere have said that no Intel iMac graphics card can be replaced, that they're wedded to the logic board. The one on this model can be replaced, I've done it. Also, some have said you can't put a 256MB, 7600 GT in a machine that originally had a 128MB, 7300 GT. Also, not true. That's what I did to my machine and it is working fine.
So here's the step-by-step on my take apart and replacement. This is just one user helping out others, PROCEED AT YOUR OWN RISK. This takes about 1 1/2 hours to take apart and 2 to put back together.
1) Install the iStat widget and monitor the temperatures for a few days and record the temperatures (to be able to verify that you've completed the repair correctly later)
2) Make a complete backup of any internal drives and make sure the backup will be bootable (use Carbon Copy Cloner)
3) Use static safeguards, like an anti-static wrist strap.
4) Get a pen a stack of paper envelopes to separate and label the pieces you remove.
5) You'll need a #2 Phillips and #6, 8, 10 Torx. Most of the screws at T-8. There are 8 T-8s holding in the LCD. They are about 1 1/4" down. You'll need a long, skinny T-8 to get to them.
6) Unplug the machine and place it on it's back on a large white sheet of paper.
7) Remove RAM door, #2 Phillips x 2.
8) Remove RAM.
9) Remove 4 T-8s along bottom.
10) Remove large rectangular plastic bezel surrounding the whole machine, tilt up being careful not to stress iSight cables. You'll need to stretch it around the RAM ejection tabs.
11) Detach two iSight cables.
12) Peel up black stickers at lower corners of speakers.
13) Remove LCD screws, T-8 x 8. You'll probably drop a few, they're pretty easy to retrieve.
14) Remove two retaining screws on right hand LCD cable. T-6 x2 Unplug cable.
15) Remove LCD inverter cable, left.
Start unplugging everything connected to the logic board.
16) Unplug cable coming from right speaker. Note cable routing, it is the only one that's a little tricky. Also, note that the left one plugs in on the right and the right one plugs in on the left.
17) Remove right speaker. T-10 Note: left and right speaker screws are different lengths.
18) Unplug ODD blower cable.
19) Unplug ODD temp cable and lift up tape.
20) Unplug HDD blower cable.
21) Unplug the HDD temp cable.
22) Unplug the camera & mic cable.
23) Unscrew the clamp securing the airport card (has two antenna cables going to it, labeled PCIE), T-6 x 2
24) Unplug SATA cable.
25) Unplug Power cable, thick black plastic harness, socket.
26) Unplug ambient temp cable.
27) Unscrew the bluetooth card, T-6 x2.
28) Unplug CPU blower cable.
29) Unplug power button cable, 2 conductor, tiny cable, bottom left.
30) Unscrew left speaker, T-10, unplug from logic board, but just leave dangling, no need to remove cable completely.
31) Remove logic board screws. Be careful to segregate them, they have different lengths and different thread pitches and thread types. Some are machine threads going into metal, some are coarse threads going into plastic.
31a) Heat sink frame to case T-8 x 2
31b) Logic board to case T-8 x 3
31c) Screws at heat sink from arrows T-8 x 3
31d) Logic board at bottom near RAM slot T-8 x 2
32) Unplug ODD ribbon cable, be extremely careful. Release plastic tabs on each side to remove. Be sure it is fully and evenly seated when you put it back later.
33) Remove logic board with attached graphics card.
34) Unplug graphics card heat sink sensor cable at logic board end.
35) Remove graphics card screws 2 x T-6
36) Remove single screw from small L-bracket on heat sink 1 x T-6
Replace graphics card.
Reverse steps, put everything back together. Be careful not to pinch any cables when you put the logic board back in. When you put the LCD back in, if you can't get the screws to stick to the driver, use some glue stick from your kid's art supplies.
Test everything. You've disconnected every cable in the system.
I torture tested the machine with a space heater on it, 5 different videos of different formats playing at the same time. No problems.
I took a lot of pictures inside the machine. As soon as I figure out a good place to post them, I'll try to add a link here.
Good luck

Greetings!
I know this is in response to your post from over 2 years ago, but I was searching on Apple's site for the max RAM I can upgrade our refurbed iMac too and it brought up this post.
Oddly enough, I've been experiencing the same screen issues and locking up on our iMac as well. I was concerned it was a bad memory module, but now I'm thinking it's the same issue you found.
Because I bought this some 2+ years ago refurbed from Apple, I'm not surprised that could be the actual problem.
I've pulled this thing apart once to replace the hard-drive which crashed about a year ago, so I'm not totally new at opening it up, but this process you mention sounds pretty intense...just wanted to get your second take on it based on what I've done thus far.
Thanks again for posting this...it was an eye-opener as to what might actually be causing our issues with our trusted Mac!

I have an iMac 1.83 ghz Intel Core Duo. The sound is suddenly intermittent, the magic mouse erratic. I'm running OS X 10.6.8. How do I correct this? Will Lion run on this machine?

Will Lion run on this machine?

Unless you have an intel core 2 duo processor or greater, you can not run Lion
General requirements-Lion
Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
2GB of memory
OS X v10.6.6 or later (v10.6.8 recommended)
7GB of available space

IMac 3.4 GHz Intel Core i7, running Lion 10.7.3, won't recognize external speaker jack, any suggestions?

iMac 3.4 GHz Intel Core i7, running Lion 10.7.3, won't recognize external speaker jack, any suggestions? Got a brand new iMac and purchased external speakers for same. Hooked them into external speaker jack and the computer does not recognize the external speaker jack. I then plugged them into the external head phone jack and the computer recognized the head phone jack. How can I get the computer to recognize the speaker jack?

Thanks "a brody," my mistake, I was mistaking the "audio in" jack for a speaker output jack. I have some Klipsch ProMedia 2.1 speakers with a built in amplifier that I am using and they sound beautiful. I do have them plugged into the correct jack, but was thinking there was a speaker out put and headphone out put.
Thanks again for correcting me, I feel much better now that I know my brand new iMac isn't defective, lol.

Dropped frames when playing section in the timeline w/audio, Viewer plays fine. Plays for 1 sec, no sound, nothing on audio meters. Problem out the blue, made no conscious changes. FCP 7.0.3. iMac, 2.7 GHz Intel Core i5. OS10.8.4. Thanx.

New to FCP. Dropped frames when playing section in the timeline w/audio, Viewer plays fine tho. Plays for bout 1 sec with no sound, nothing showing coming through the audio meters. Problem came out the blue, made no conscious changes to settings. FCP 7.0.3. iMac, 2.7 GHz Intel Core i5. OS10.8.4. If any other info needed please let me know, will be happy to provide it. Thanx.

Thank you for the help. Below is my Source footage and sequence settings.
The other footage I have on the timeline is an mp3 file made in Garage Band and some footage I sent to Motion to edit. I do have some offline media on there since I switched computers but FCP had been working fine for a few months with it on there. I have not tried trashing my FCP Preferences. If I did would I have to back up my project?

Upgrade path for iMac 2.4 Ghz Intel Core 2 Duo from OSX 10.5.8 to mountain lion

Hi,
I have an Apple iMac 2.4 Ghz Intel Core 2 Duo with 4 Gbytes of 667 MHz DDR2 SDRAM.
It is currently running MAC OSX 10.5.8 --
I would like to know the proper upgrade path to the most current version of OSX which is
compatible with this hardware.
Thanks!

The starting point is to call Apple at 1-800-MY-APPLE and ask to purchase a copy of Mac OS 10.6 "Snow Leopard." It will cost about US$20 plus shipping. When you receive it, install it and use Software update to get to OS10.6.8; the updates are free to that point.
Now you will have the App Store app in your Dock. You can use that to purchase Mac OS 10.8 "Mountain Lion," the lastest. According to the MacTracker database, your iMac--which is either a Mid-2007 or Early 2008--can support 10.8.
CAVEATS:
• your iMac is at or near the minimum level to suport 10.8; performance may not be stellar
• if you currently run any old PowerPC apps (like Office 2004), they will still work unders 10.6 but no higher. You will have to upgrade to newer versions to continue using them. Office 2008 runs on either PPC or the newer Intel Macs. Office 2011 runs only on Intel Macs.

IMac 2.8 Ghz, Intel Corei5 with 8gb of ram takes 5 minutes to start up! why so slow???
