  I have a late 2009 iMac. When I tried to upgrade to El Capitan. He said that the CHIP shows the h/d is a failure and can not be updated. I have install an external withEl of h/d Cap but it is very slow. the h/d is USB 3 but the iMac's USB 2. the h/d is only 5400 RPM. a 7200 RPM 7 / would accelerate the iMac?

  No, because the limiting factor is the computer is USB 2.0, which is how it connects any external drive apart the external drive. As USB 2.0 is much slower, there is no real advantage to a 7200 RPM drive. What you need is a Firewire enclosure that supports FW800 which is much faster than USB 2.0.

• Using Late 2009 Imac as external display for PC with display port 1.2

  Hi all

  Thanks for your time.  I searched for a definitive answer to this question before I go ahead and make a purchase.

  I have a Late 2009 Imac 27 ".  I would like to use it as an external monitor for my new PC, which is a graphics card EVGA GTX 970 with a displayport 1.2 output.  I'll be able to use a DisplayPort / mini displayport cable to connect to my Imac to use as an external monitor for my PC.

  The Imac doesn't have the speed I need for photo editing but I like the contrast and the size of the screen offers.

  Any input would be appreciated!

• late 2009 iMac desktop computer - time to go?

  My desktop iMac computer has six years this month, [late 2009 model] and provided the fault all this free time. I have upgraded the RAM 12 GB of 8 GB a year ago.

  My iMac is linked to a Maxtor external drive old eight year which runs on Firewire 400 [Mac is up to 800]. External drives is full at 85%, while the internal drive of the Mac is only 10% full.

  The IMac is scrambling to run Photoshop elements 13. It's just excruciatingly slow in editing, but OK mode to the Organizer. It is also slow, but less than software image of Macphun so editing running creative Kit 2016.

  This slow performance is noticeable when I went to 13 items in Photoshop. I wonder if it's related to the lack of speed by updating the internal hard drive and make the Time Machine backups running every hour so at the time where he finished one, it's almost time to start over. Recovery from the external drive is OK.

  To get a new 2 TB external hard drive, to say I seem to need firewire 800 and Thunderbolt. LaCie is the brand only I found which is an external hard drive at once [Thunderbolt will be required when I buy a new IMac]. My IMac built in wifi is not compatible with the new Apple Time Capsule.

  The problem has a number of different options available. Who would you?

  I have 2 mid iMacs 2007 that work very well.

  You have been the victim of misinformation.

  There are well 2 t (and more) disks that use USB or FireWire available. No necessary crush.

  WiFi from your iMac is compatible with the new Apple Time Capsule.

• Late 2009 iMac Sierra gel & incomplete close

  Hi all

  I did a clean install of Sierra on my iMac late 2009, 3.60 GHz Intel Core 2 Duo, the 12 GB of RAM, a 1 TB drive, ATI graphics card. Everything seemed to happen. Now, I have two problems:

  1. at least twice daily than the iMac just hangs. The mouse moves, but can not select anything. Cmd - Tab will not pass applications. Keyboard does not respond. All I can say is that I always Mail, Safari, & Open Office 4.1.2 running. Have to hold the power button to turn off and restart.

  2. at the end of the day, when I stopped, the process is not finished and I just get a black screen (computer for desktop is black, but the items on the desktop are not visible), with the only docking station. Still, the only way out seems to be to hold down the power button to turn off.

  Anyone else having these issues? Is it that I can save for a clean install of Yosemite that worked perfectly before?

  Many thanks in advance,

  gimbers

• Update late 2009 iMac 21.5 "GPU

  I have a 21.5 "iMac, 3.06 GHz Core 2 duo with a SSD and 8 GB of RAM. The video card is the NVIDIA GeForce 9400 with 256 MB of VRAM. Is it possible with this model, to level or replace the GPU at all? May not deal at all with Final Cut Pro. I use El Capitan.

  Otherwise, I'll continue to use my MacBook Pro with Radeon R9, but I would if it had a better GPU.

  Thank you in advance,

• Late 2009 iMac Memory Card Slot Gone Bad?

  My memory card seems to have stopped working. Is there a way I can tell if it's the memory real slot hardware vs whether software or my SD card.

  I have reset PRAM and SMC. I had to reset the PRAM periodically to retrieve my startup chimes. I was wondering if they can be connected.

  I did first aid utility disk on the map and it seems to be OK, for what is disk utility is.

  It started with my card being ejected unexpectedly. If I reinsert the card, the card is not recognized.  This would solve usually solve the problem until the next time.

  Any help appreciated.

• 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!

• What SSD for early 2009 imac?

  Hello

  I have a question to choose the good ssd for my imac 7y/o (9.1) since early 2009.

  I found a few good SSD as the samsung 840 BX100 or critical, but I've also read several times that a ssd sata3 will use sata1 when installed on a sata2.

  And that is why it is better to install a sata2 ssd.

  IS that still the case today? Given that these messages are coming from 2013.

  Or is that I can put in an ssd sata3 and it will run on sata2?

  Kind regards

  Ivo

  SATA III drives that use the Sandforce controller will come back to SATA I speed if installed on a computer that uses the Nvidia MCP79 SATA controller. Samsung does not Sandforce. My Macbook in early 2009 with a Samsung 840 (pre Evo, not Pro) negotiates the SSD SATA II speed, connected to the MCP79.  OWC also still sells SATA II disks, I have one in my late 2009 iMac. I chose this drive, even if it was more expensive because OWC insisted that my model should have the Nvidia controller but in reality it has controller Intel 5 series. I didn't take my iMac except more than once.

  Confused? Yes I know...

• 2009 iMac has none showing after restore and hard disk crash

  My 2009 iMac running 10.9.5 Mavericks locked up and I had to restore it from backup. After I restored it, it made 2 backups and then crashed. When I tried to restore it again there is no hard drive available. I got when starting was a folder flashing with an exclamation mark. When I started a drive (10.6) there was no available hard drive. The Profiler system showed no applications and no hard drive. Does anyone know how ix, or it is not repairable? Thanks, DJ

  Reboot into Recovery Mode and then reformat the drive of DiskUtility in recovery. Try again.

• 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?
