Memory Upgrade: 27" iMac, late 2009

Hey everyone,
Quite late to the game, but definitely should upgrade my imac's memory from the standard 4gb - However my mac doesn't show up in the shopping aides some of the manufacturers have on their homepages, so the subject is a bit shady.
Am I still able to track down the working hardware for this particular computer?
If so, any suggestions? Would these do?
Thanks!

I also have a late 2009 27" iMac installed 16 gigs of crucial memory, I ordered the mid 27" iMac memory running at Speed: 1333 MHz been running them without a problem for two an half years.
Here is the link. http://www.crucial.com/usa/en/compatible-memory-for/Apple/imac-2*8ghz-intel-quad -core-i5-%2827-inch---ddr3%29-mid-2010
I have Yosemite install running smooth with no issue. Now I'm waiting for Kodak printer driver update.

Memory upgrade on iMac (Late 2006)

I want to upgrade the memory on my iMac (Late 2006). My present memory is 1GB 667 MHz DDR2 SDRAM. I am getting that information from the System Profiler. That (one) module is in one Memory Slot, and the other Memory Slot is empty.
The manual says the following:
+Your iMac comes with at least 1 GB of Double Data Rate 2 (DDR2) Synchronous+
+Dynamic Random Access (SDRAM) memory installed. You can add 1 or 2 gigabyte (GB)+
+memory modules for a maximum of 3 GB of memory. Memory modules must meet the+
+following specifications:+
+* Small Outline Dual Inline Memory Module (SO-DIMM) format+
+* 667 MHz, PC2-5300, DDR2 compliant (also referred to as DDR2 667)+
+* Unbuffered and unregistered+
And it also says the following:
+Your iMac has a top slot and a bottom memory slot. You can add a memory module to+
+the bottom slot and remove the memory module in the top slot to replace the+
+installed memory. You can add a 1 GB or 2 GB memory module for a maximum of 3 GB+
+of memory.+
I guess I should just do as Apple suggests and add a 2GB module to the other memory slot, to maximize the total memory in the computer at 3GB. But does anybody have any alternative experiences or suggestions? Should I perhaps add another 1GB module to the other Memory Slot so that they are both equal? Has anybody tried adding 2GB to each Memory Slot? What happens? It seems odd or unbalanced to have a 1GB module and a 2GB module as Apple suggests. Any opinions from people experienced in this would be welcome, and I thank you in advance.

Hi rosalarose
To check how much memory you have and your memory usage go to: Applications > Utilities > Activity Monitor and select System Memory.
Your problem sounds more like a Software problem with Safari than a Hardware issue with the Memory. Instead of piggybacking on someone else's thread you should post a New Topic of your own here or in the Safari section of the Forum with a more detailed explanation of your problem.

Can I factory restore an IMAC Late 2009 without the orginal DVD's?

Can I factory restore an IMAC Late 2009 without the orginal DVD's? I was given a computer and want to remove the previous owners user login and passwords. I want a fresh install like it was bought new.

You can create a new Admin User in System Preferences then delete the current User. This will give you a clean User but the base system files might have extensions etc installed.
If you upgrade to Mavericks, then you would wipe the computer giving you exactly what you want.
While your computer might meet the requirements, also check your applications for Mavericks compatibility here: http://roaringapps.com/
Make sure all your software like Microsoft Office and Adobe CS Suites is compatible with Mavericks.
OS X Mavericks: System Requirements
To install Mavericks, you need one of these Macs:
          ▪          iMac (Mid-2007 or later)
          ▪          MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)
          ▪          MacBook Pro (13-inch, Mid-2009 or later),
          ▪          MacBook Pro (15-inch or 17-inch, Mid/Late 2007 or later)
          ▪          MacBook Air (Late 2008 or later)
          ▪          Mac mini (Early 2009 or later)
          ▪          Mac Pro (Early 2008 or later)
          ▪          Xserve (Early 2009)
Your Mac also needs:
          ▪          OS X Mountain Lion, Lion, or Snow Leopard v10.6.8 already installed
          ▪          2 GB or more of memory <--- I suggest 4GB as minimum
          ▪          8 GB or more of available space

IMac Late 2009 i7-2.8Ghz Poor Performance

My iMac Late 2009 seems to run very slowly after a clean install of OSX Mavericks. I am not sure that happened after the clean install. But now i have noticed it.
I am using mainly photoshop. Everything is sluggish. Moving or resizing layers.
Generally it runs very slow with everything.
The surprising fact is after i ran GeekBench.
The average score for 32-bit test is about 2000 for single-core and 7000 in multi-core
My results are: 700 for single-core and 3000 in multi-core.
Few users seem to have about the same results as me..
My specs are:
Late 2009 iMac
intel i7 2.8Ghz
12GB of Ram
ATI Radeon HD 4850 512 MB
Kingston SSDNow V300 120GB with trim enabled (i upgraded my ssd after my old corsair 90GB ssd broke!!!)
OSX Mavericks 10.9.3
You can see all the iMac Late 2009 i7 2.8Ghz results here.

Do you have any suggestions?
it drive me crazy!!
I am considering a clean install but i want to wait for the Yosemite release.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the behest of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
Copy a line of text in this window to the Clipboard.
Paste into the window of another application.
Wait for the test to run. It usually takes a few minutes.
Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start Time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

IMac late 2009 - beach ball of death

My iMac is hanging a ridiculous amount - Every 30 seconds or so, no matter how few applications are running, I get the beach ball of death. It'll typically stall for a minute or more. Ugh.
I upgraded the RAM to see if that would fix the problem, and it didn't (the computer still hangs when available RAM is in excess of 10GB). I've run the Apple Hardware Test, and there were no problems reported. I've run virus scans, and there were no problems reported. I've upgraded the machine to OSX Lion, and have all of my software updated to current versions.
Please let me know if you have any ideas for a solution!
System specs:
iMac Late 2009, 21.5 inch
Processor 3.06 GHz Intel Core 2 Duo
Memory 12 GB 1067 MHz DDR3
Graphics ATI Radeon HD 4670 256 MB
Software Mac OS X Lion 10.7.2 (11C74)
Thanks,
Mike

Yes... took it back to Mac Store who sent it to their depot who did a deeper scan and it was a failing harddrive. Thank goodness for Time Machine and having backups... I am not as stressed as I would have been. However, they reinstalled it with Snow Leopard instead of my purchased Mountain Lion. When I brought it home I imported from Time Machine. But another issue reared its head and fought with its password issues (seriously, hours of work there) only to find that I could not upgrade from SL to ML on my disc. I did a check for software update from the Apple Icon (no Apple Store in SL) and it downloaded 1.6 GB of 5 updates (what appears to be the Java and others that are making the rounds currently). When this installed I was unable to log in at all, unable to get past the login screen, with some heavy duty serious lag and blue screens. So I am BACK at the Mac Store and having them do a complete wipe (again) and installation of Mountail Lion this time. In theory I should be able to take my machine with a new harddrive, Mountain Lion installed, back home and import form Time Machine.
Preach it from the rooftops and mountains... buy an external hard drive and install Time Machine. Seriously! Do it now! I am very happy that I finally, after a year, got around to doing this in time.

I just installed 16gb in my 21" iMac late 2009 and I have macbook 13" late 2008. Can I put the 2gb 2rx8-8500s-07-10-f2 ram in the laptop. Does anyone know the difference of 2gb 2rx8-8500s-07-10-f2 and 2gb 2rx8-8500s-07-10-f1 . thank you!

I followed your instructions and installed Developer Suite 10G on Windows Vista Home Premium edition. I have Oracle 11G DB running on the same machine.
Two points, Steve:
1. When I tried to set the maximum virtual memory to 6110 an error message displayed from Windows and told me that I can't set the maximum virtual memory to more than 4096. I set it to 4090 and it worked and I got nothing wrong during the installation process.
2. After installing JInitiator and disabling Java on Firefox I called the http://127.0.0.1:8889/forms/frmservlet page and everything seemed to be OK because the Oracle Forms Services logo appeared and then a successful installation message appeared , but as I clicked (ok) to continue a gray screen appeared inside the browser (like the one displayed when you try to run a Java applet inside a browser) and then I wait to death till something appears but sadly nothing. I just get a blank gray screen inside my Firefox browser.
Do you have any idea what to do to solve the problem?

Why no airplay mirroring for imac late 2009

Just upgrade to find the key feature Airplay Mirroring is not supported for my iMac late 2009. WHY??

Only some 2011 machines and newer are supported (excluding any Mac Pros).
The best theory is to do with onboard h264 encoding in Ivy Bridge and Sandy Bridge Intel chips:
http://en.wikipedia.org/wiki/Intel_Quick_Sync_Video
It seems likely that Apple feel a software only solution would not be feasible/acceptable on earlier models though Airparrot puts that in doubt.

IMac late 2009 reads only 2GB RAM,I have re-installed the card 10 times now,what else could I do?

iMac late 2009 reads only 2GB RAM,I have re-installed the card 10 times now,what else could I do?

Please give us some more details on what exactly has gone wrong with your iMac.
What size RAM module/s are you trying to install and where did you purchase the RAM module/s from?
RAM has to be installed in matched size pairs.
Make sure the RAM module clicks into place. You need to apply a little bit of force to get the module to slide in and clIck into its module slot location.
Correct, compatible and reliable Mac RAM can ONLY be purchased from online RAM sources Crucial memory or OWC (macsales.com).
If you purchased RAM from ANY other source and still can't get the RAM to work, return it for a full refund and buy RAM from the sources I have listed.

Mountain Lion for iMac Late 2009

Is Airplay the only feature that wont work on the older Macs? I don't use Airplay with My iMac (Late 2009) so it's no big deal, its all I hear people complaining about except that it slows down their computers. Is this an older version issue too (speed)?
I like all of the other features, if Airplay is the only thing that won't work then I'm going to download but if there are other issues with older version computers I would like to know. Thanks

Primarily yes. Mt. Lion is like ANY OS X upgrade. Prior to upgrading your system it should be operating perfectly, if it isn't address your problems first or your upgrade could be a disaster. Check to see your apps and peripherals are compatible and then if everything is OK you can proceed. Before beginning your download BACKUP!!!! It's wise to have a minimum of 1 backup but when it comes to backup redundancy is a very good thing.

IMac late 2009 gives beach ball. All test return normal.

I have an iMac late 2009 model 27 inch. update to Mavericks (10.9.1)
Returning from holiday, I found my iMac dead slow, with spinng beach balls on every click. Until now I have done ....
Create new user account, logged in as this new user.
reset PRAM / NVRAM
boot up in safe mode
boot up in recovery mode, perform disk test. (all normal)
I managed to copy the most important directories to an external storage. Got more and more read/write errors.
iMac had become unusable slow.
Made bootable USB stick, used this to boot and did a complete HD erase.
Clean installed Maverick.
Problem still persist.
Performed AHT (Apple Hardware Test) in extented mode. No error founds.
Performed Black Magic Disktest, around 110 MB/s seems normal speed.
After reboot, the first application start up fast (which gives me hope) but starting the second app, takes several minutes with this spinning beach ball.
Anyone here having simular problems or otherwise can point me to a solution?

Thanks for you advise. I did a clean install, so without any third party software like Trusteer Rapport.
On you advice I ran EtreCheck. This is the result:

27in iMac (late 2009) ATI 4850 drivers problem in Windows 7

This iMac is less than a month old. Windows 7 was working fine until a couple of days ago. While at the Windows 7 desktop the screen pixlated and froze. A tip bubble appeared in the notification bar that said the ATI driver quit but was recovered. The screen went black then restored itself. A moment later the whole thing occurred again. Is this a known issue? Is there a fix? Thanks for any help.

BANDING AND DRIVER CRASHING SOLVED:
I bought the following iMac on April 18, 2010 to run Windows 7 and Autodesk REVIT 2011.
27" iMac (Late 2009)
Intel Core i7, quad-core, 2.8GHz
8GB (4x2GB) memory
1TB Hard Drive
ATI Radeon HD 4850 512MB Display Adapter
Apple Magic Mouse
Apple Wireless Keyboard
Apple BootCamp with Windows 7 Ultimate
Installed OSX, downloaded and installed all updates.
Installed BootCamp 3.1
Installed Windows 7 Ultimate 64bit and had the problem of the black screen during install. This was solved with the fix from apple support (copy latest drivers to a flash drive and continue to install windows). This resulted in apple windows driver 8.681.0.0 and the 16 bit color with banding. Rolled back the driver to 8.661.0.0. The banding issue was solved, but then had intermittent crashing (reset of the driver) in Chrome and REVIT 2011. This driver caused yellow "dots", then lockup and generally would reset. Very disruptive to REVIT.
SOLUTION:
Went to ATI website and downloaded Catalyst 10.4, then manually installed ATI Mobility Radeon HD 4850 display driver version 8.723.0.0. This display driver has 32 bit color, does NOT exhibit the color banding and has not had screen flicker, driver resets, or crashing in any programs run so far. I use this computer only for Autodesk REVIT 2011. The ATI HD 4850 is not officially supported by Autodesk, but I am able to run REVIT 2011 with hardware acceleration and anti-aliasing with no problems. So far that has been only for one day, but was not able to go more than a few minutes with the previous drivers.
I have not run any speed benchmarks yet, but compared to my Windows 32 bit XP machine, the performance is much improved.

IMac late 2009 with 6GB RAM, slow with Yosemite

Have you ever used that small pc computers with slow processors, called netbooks? This is what my super fast iMac late 2009 (6GB RAM) with Mavericks turned into, after upgrading it to Yosemite OS X.
I mean, processor itself doesn't look to busy, but user experience is click and wait (when nothing happens, I almost want to click again but then action happens). Opening window animation is like slide show - it is not smooth as it was before, with Mavericks.
Anybody with iMac late 2009 can confirm this or is it my setup only?
I have the basic late 2009 model, except I upgraded it to 6GB RAM soon after I purchased it.
This is how my About this Mac looks like:
And this is how my hard disks look like:
Nothing specially busy here, just slow Yosemite. When I open Safari, Mail, iPhoto and iTunes, it is not good to open any other app, because I might wait much more. I caught my self using iPad while opening fifth app on iMac (just to get an idea, how very slow it feels).

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
The title of the Console window should be All Messages. If it isn't, select
SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select

Constant Disconnection from Airport Extreme Networked iMac (late 2009)

I keep trying to copy fairly large files (2-7GB) over my Aiport Extreme (latest—5th generation) network from a early 2011 Macbook Pro to a 27" iMac (late 2009), and I keep getting disconnected from the iMac while the file is copying. I've tried repairing permissions on every computer in the house and restarting them, but I'm still having issues. I have no issues copying files to another late 2011 Macbook Pro in the house, so it seems to be happening only when I copy them to the iMac. The iMac is running Snow Leopard and the Macbook Pros are running Lion, so could that have something to do with it?
Additionally, I had been trying a wireless extended network with another previous generation Airport Extreme, but I found the connection wasn't much stronger with the extension, so I've just been leaving the second Airport Extreme unplugged. I've had that unplugged for months and haven't had any issues, so I don't think that's the problem.
I'm hoping this isn't a sign of something being wrong with the Aiport card in the iMac. Anyone have any ideas?

Bump?

I can't seem to get my iMac (late 2009 model) into automatic sleep mode. If I manually put it into sleep I don't have any issues. I used to solve the issue by running "PleaseSleep" application but that doesn't work anymore since Lion.

I can't seem to get my iMac (late 2009 model) into automatic sleep mode. If I manually put it into sleep I don't have any issues.
I used to solve the issue by running "PleaseSleep" application but that doesn't work anymore since Lion. I now want to fix the underlying problem.
I'm not running any weird background processes and in my energy saver settings I've tagged "put the hard disk to sleep when possible:, "allow power button to put computer to sleep" and "automatically reduce brigthness". All pretty standard.
Is there anyone who can give me some pointers ?

Today I solved the same problem for my iMac running Snow Leopard. See https://discussions.apple.com/thread/3008791#15947706. The method may help you, too.
For me it was the DynDNS Updater preventing my iMac from automatically entering sleep mode.
To my knowledge the cause of this sleep problem can only be a peripheral device or a process. So I suggest to first unplug all peripherals and test whether that's the cause. If not, I suggest to terminate one process after another and to test automatic entering of sleep mode after each. Start with user processes; continue with system process if necessary.
At least that's the way I found the offending process. Fortunately, I was able to change the configuration of that process to allow again automatic entering of sleep mode.
Good luck!
