my 27 Imac late 2009 became very slow

My 27 Imac late 2009 became very slow - I think especially after I've upgraded to El Capitan. Otherwise, everything in the computer works perfectly and I m using only 200 I have the 1 TB. Onyx and other tests can't find anything wrong. I mainly use my computer for word documents and to manage his photos about 30 000. The internal memory is 2 x 2 GB. Does anyone have any suggestions of what I could do to speed it up? Thank you.

I wish I had an answer, but all I can do is rather echo to your problem. I have a 19 mid-2007 "iMac, contributed to the maximum with the RAM, 1 t disc hard less that half full, who did the same thing - he has worked with El Capitan until I updated to the latest version. Once that has happened the machine became so slow as to be unusable. It would take ten or twelve minutes to record a mouse click. When I restarted the machine, it took 32 HOURS to start (Fortunately it isn't my main Mac production).

Last week, I tried all the remedies of common sense - by removing unused software, keeping an eye on the activity monitor (there is nothing fancy here), etc. Finally, I did all the stuff start, PRAM, run utilities disk (no noted problem) and even tried to reinstall El Capitan to a bootable USB I did with my first Mac, the reinstall, but seemed not 'take' somehow - he wanted to repeat the installation procedure again and again.

I use the little Mac for Internet, e-mail and (as Karlis2) deal with some of the oldest pictures in my files - I'm sure that I have pictures on Time Machine, so I'm not too worried about it, but this was the first Mac way back in the day, I bought with my money and I'm a little sentimental on and would like to resurrect if possible... I wonder if there is a way to restore the operating system to an earlier version and it would make a difference?

  • Can I put a Seagate FireCuda drive in my iMac late 2009?

    Apple Hardware Test (AHT) says that my SATA drive, 1 TB in size, has a problem.  Nothing specific indicated. The code given is: 4HDD/11 / 40000000:SATA (0,0)

    I was testing because of the prob trying to get a good download of macOS Sierra.  Looks like I need to replace a hard drive first.  I have an iMac late 2009 with a Core i7 quad core, 16 GB DDR3 1067 Mhz ram and ATI Radeon HD 4850 graphics card.  I can put a SSD in this unit or am I stuck with the Barracuda drives.  I'm looking for FireCuda readers and like what I see and read about them.

    If you want an SSD, then I highly recommend:

    • Samsung 840.
    • OCZ ARC100 and other models.
    • OWC 3 G SSD.

    The foregoing is all compatible and should work well. Your model only supports SATA 3 Gb/s speeds due to the controller, so don't waste your money on more expensive discs of 6 G or 6 Gbps because they work faster than a car of 3 G. If you decide on a 6 GB drive, however, they must be compatible as they work on the slower bus of 3G.

  • IMac late 2009 - 5 yellow bars on the screen - sometimes...

    Hi all..

    I recently bought an iMac late 2009 really nice second hand.  It worked wonderfully for a few weeks and I was about to become a mac convert.

    All of a sudden things have changed.  I pulled to the top of the machine first thing the morning only be greeted with lines to the bottom of the screen and a stall on a white screen.  The next day, it worked fine for a while.  Then the problem comes back for an hour or two.  Then back to yellow bars.

    I pulled up to my PC and started researching and found suggestions that this could be a graphics card problem.  After some time of reading and discovery, I pulled the top of AHT, and he advised me that there is actually a problem with the machine, and it's a sensor on the HARD drive.  Then, I would expect an additional error that could somehow link to the screen and absolutely nothing.

    Now, I know that historically the 27-inch late 2009 iMac screen / GPU has been examined by several different sites and forums but it is now an old machine and I don't know what to do.  What is a HARD drive failure?  Seems very unlikely but the only error listed... The flaw is GPU displayed on AHT down?  If this graphics card has received a "reformatting of oven" at a given time in its life and Ive been sold a dunce?

    Any advice would be great.  I don't have an Apple store near me and I don't know if they would even look at a machine this old.

    Help, please... My brief relationship was positive that ended quickly in tears!

    Top of desktop Mac became very slow all of a sudden. Could there be any virus. How do I solve the problem

    When you see a beachball cursor or the slowness is particularly bad, note the exact time: hour, minute, second.

    These must be run as administrator. If you have only one user account, you are the administrator.

    Run the Console application in one of the following ways:

    ☞ Enter the first letters of his name in a Spotlight search. Select from the results (it should be at the top).

    ☞ In the Finder, select go utilities ▹ of menu bar or press the combination of keys shift-command-U. The application is in the folder that opens.

    ☞ Open LaunchPad and start typing the name.

    The title of the Console window should be all Messages. If it isn't, select

    SYSTEM LOG QUERIES ▹ all Messages

    in the list of logs on the left. If you don't see this list, select

    List of newspapers seen ▹ display

    in the menu at the top of the screen bar.

    Each message in the journal begins with the date and time when it was entered. Highlight date back to the time you noted above.

    Select the messages entered since then until the end of the episode, or until they begin to repeat, whichever comes first.

    Copy messages to the Clipboard by pressing Control-C key combination. Paste into a reply to this message by pressing command + V.

  • iMac became very slow and unresponsive

    Hello

    I have an iMac which, in the last two days, suddenly became unusably slow. Almost every click brings up the spinning beachball even just after a reboot. iTunes cannot play a melody without pausing every minute or two. Same Safari is really slow, so I have still not tried more demanding such as Lightroom.

    Its an iMac mid 2010, 8 GB RAM, 1 TB HD with 305 GB free. Im running El captain, 10.11.6

    Any ideas what could be causing this or what I could do to remedy the situation? IM thinking I have to go through the pain of wiping the hard drive and reinstall everything. But I'd really rather avoid because I was planning on getting a new iMac when they release then them and I don't want to go through all that process again.

    I hope someone has an idea of something I could try before doing this?

    Thank you.

  • Mac Mini became very slow all of a sudden

    This morning, my Mac Mini became very, very slow. It's a 2009 with 4 GB of RAM and hdd 120Gb standard.

    I run with a keyboard and bluetooth mouse and due to its slowness, I wanted to run the hardware test to see what was wrong. (As is always the original HARD disk, I am wary of its remaining life expectancy). However, everything I try, I can't start anything on the mini as a normal reboot. If I have D, hold down option-D, hold SHIFT to safe mode, nothing seems to influence his start-up.

    Any thoughts? And also, suggestions of things to check?

    Run > Etrecheck.com and post back here with the results.
