Early 2009 iMac and Sierra

What will happen if I tried to install Sierra on my iMac in early 2009? He would install at all? Would it brick the computer?

  • iMac (24 inch, early 2009) freezes and then thaws

    iMac (24 inch, early 2009), frequency of 2.66 Ghz Intel Core 2 Dup, NVIDIA GeForce 9400 256 MB - no reason apparent other than a mouse click randomly, the computer freezes for anything between a few minutes and maybe 15-20 minutes.  Then, he thaws and answer to all clicks made while it was frozen.

    I started in 'safe' mode and disconnect all external devices.  It occurs again, but perhaps to a slightly lesser degree.  The overall reaction is slow, with simple activities, taking a lot of time.  for example to move a small folder to a new location, took nearly a minute to complete.  Ejection of an external drive, took a minute to complete etc.

    This started when I upgraded to El Capitan and has been progressively worse since then.   All ideas are welcome please?

  • 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...

  • Early 2009 iMac running hot. Hard drive problem?

    Hello world

    I have an early 2009 24 "iMac. (iMac9, 1, 2.93 GHz Intel Core 2 Duo). I am currently using OS X 10.11.4.

    This problem started, summer 2014. My iMac has been in storage a year since March 2015. Here's the problem, when it started it was summer and very hot. I didn't have air conditioning. I got this iMac from April 2011. Bought from Mac of all trades. Obviously, they heat up on top, or at least this one does. The hard drive is a Western Digital WDC WD1001FALS-40K1B0, 1 TB drive.

    At the point where I was running DiskWarrior, who reported that my hard drive was running too hot. The reader otherwise verified fine and so I downloaded Fans of Mac control, looked up what the operating temperature should be for this hard drive and set it to increase the fan speed, if necessary. Now 5182 rpm, it turns the hard drive cooling fan, and he reports 127,4 ° F. The room temperature is 82.4 °.

    Now, let's move forward to this last week. I've had my Mac for storage, he had been in the garage of a friend of year-round, is his box. From the beginning it upward, it froze soon after establishing the office. I started on the recovery partition, and DiskUtility found that it could not solve problems. So I started from the eDrive TechTool Pro partition and run DiskWarrior. That was fine until the computer froze again. To reboot the partition e could not climb. The recovery partition would enter to Midway through the boot process and then hang. It's the same problem I was trying to start normally.

    So after a long day of trying everything (I don't have a disc of starting of any kind, that I still have stuff in storage), the Mac finally started in the recovery partition. I ended up having to reformat the hard drive, make a new installation of 10.11 and restoration of my Time Machine backup.

    After another day of tweaking, everything worked fine. Except the drive is always hot.

    Today, it's back to freezing on me. I started the eDrive and TechTool Pro check sensors and generate a SMART report. The SMART report verified the reader, but watch it turns slightly on the warm side. And that was with the fans to run fast.

    Then, after all that, I'll try to get an opinion on the health of the hard drive. If I put the fans for normal speed, now it is 2638 rpm and increase, and the reader is 138.2 ° F. This seems too hot for me. You can't touch the top of the computer for a long time. It is too hot.

  • 2008-2009 iMac and vertical lines endless boot loop

    My father has an iMac from 2008-2009 and it has been fine.

    However yesterday it suddenly developed vertical lines on the screen (see below). These lines seem to be 'above' the Apple logo. Unfortunately I can not access the info from the computer

    The Mac is stuck in an endless loop of startup where it never gets beyond the Apple logo and turn the circle loading.

    I started using the option key pressed and tried to the recovery for the boot partition. This again goes to the Apple logo and the rotating circle gray until he says: "If you want to continue in English press the return key" what I'm doing and then nothing (the circle stops spinning). Same thing happens when the safe boot mode.

    I also tried to boot from the recovery drive (separate USB) and nothing... Fortunately, I can access its backups like he always its data.

    I also tried the mode via Firewire to my laptop and disk target hard iMac mount (although the Firewire icon appears on the screen of the iMac).

    I also tried re-creation of the AMFR2 and MSC.

    My guess is that it's a failure of motherboard somewhere as it seems beyond normal graphics card. For some reason any my store does not have engineering appointments at the moment, so cannot take it.

    Is the consensus, that it is a dead iMac? Thank you

    (Note the "burrs" on screen is from my phone, not on the iMac!)

    Hi, Steve Hayes1,.

    I had one come in the other week with these lines - GPU issue. Replaced it and worked like a charm.

    With respect to the infinite loop, try to start from an external drive and load an operating system. Should I still do the endless loop?

    Kind regards

    If I use a mini port screen hdmi adapter, can I connect a TV external 48 "1080 p on my iMac in early 2009.

    EveryMac.com seems to say there is a limit of 30 ", but they throw in some dimensions of the screen of

    2600 x 1600 and I don't know how this fits - I get my TV is 1080 p - 1920 x 1200?

    Any clarification would be appreciated.

    Take a look-> On Mini DisplayPort to HDMI - Apple Support adapters

    You shouldn't have any problem due to the size of your TV, but more probably to the resolution of your TV. However, your iMac supports up to 2560 x 1600 resolution for an external display and your TV got a lower resolution (1920 x 1080), so it should work.

    (Please note that your iMac does not support streaming audio via the Mini DisplayPort connector, then you will not get audio on your TV).

  • iMac 24 "early 2009. 4 GB of RAM to 8 GB upgrade?

    I have an Apple iMac 24 "early 2009, 2.66 GHz Intel Core 2Duo, NVIDIA GeForce 9400 256 MB.  Memory 4 GB 1067 MHz DDR3, but I would like to upgrade. I just install OS X El Capitan and having been informed that a RAM upgrade is a good idea?  Eager 2 x 4 GB (8 GB) of RAM.  I would like to know one) is that a good idea? and (b) where can I get quality from a reputable provider RAM as there is a gap of GBP £30-£40 cost online.  I live in England.

    The upgrade to run El Cap is a great idea. Buy quality ram Crucial http://www.crucial.com/ or OWC http://eshop.macsales.com/

    Expedition to the France can do direct purchase OWC too expensive, but you can find their ram at Amazon.

  • Can I update to El Capitan directly from Lion?  I have an iMac 24 "early 2009.  I want to do this?

    I think the Lion upgrade completely to El Capitan.  First of all, can I do this? I have an IMac in early 2009.  Are there reasons why I wouldn't want to do that?

    Well, we can tell you that you should or should not pass, that decision is yours alone.  We can tell you the benefits of upgrading, but ultimately, it is for you to take advantage of them if you wish.

    To upgrade to El Capitan, your computer must be one of the following conditions:

    • iMac (mid-2007 or newer)
    • MacBook (late 2008 or early 2009 or newer aluminium)
    • MacBook Pro (Mid/Late 2007 or newer)
    • MacBook Air (late 2008 or newer)
    • Mac mini (early 2009 or newer)
    • Mac Pro (Early 2008 or newer)

    So, if you have a 2009 iMac, then Yes, your computer can handle the upgrade.  You would from the App Store.  If you choose, make sure that you back up your system with Time Machine or something like CarbonCopyCloner.  Obviously, the upgrade: a more stable, secure system, and that you use the latest version of Safari, which is more stable and more secure than previous iterations.

  • Can I put my 24 inch Dual Core IMac (early 2009) 4 GB ddr3 1067 Mhz RAM to 16 GB ddr3 1600 Mhz (it says maximum of 8 GB for this model)?

    Can I upgrade my 24 inch Dual Core IMac (early 2009) 4 GB ddr3 1067 Mhz RAM 16 GB ddr3 1600 Mhz? I read that it only can be upgraded to a maximum of 8 GB but I'm not sure whether that was when they were sold or if the maximum capacity of the computer can take.

    Thank you for your help,

    Jacques Bizot

    You can upgrade the RAM, but 16 GB ddr3 1600 Mhz is NOT designed for your iMac. Please use the RAM specifications correct, iMacs are extremely sensitive to the RAM and require the correct specifications and high quality RAM. Advanced users on these forums tend to recommend Crucial (buy directly from them) or if you are in the USA, RAM from OWC (www.macsales.com).

    Do not buy RAM in your store, the local computer or cheap RAM at best, it's probably a waste of time and at worst it will simply not work.

  • Fact to have integrated Wi - Fi AirPort Extreme middle of my iMac (early 2009 model) wireless networking is wireless?

    Fact to have integrated Wi - Fi AirPort Extreme middle of my iMac (early 2009 model) wireless networking is wireless?

    Yes, this does mean that it can access wireless internet if you have a router like Terminal Airport Express or Airport Extreme wireless. Assuming you're not planing to carry your iMac autour with you and use it at Starbucks.

  • IMac early 2009 negotiated 1.5 Gbps speed

    I have an iMac early 2009 in which I installed a Sandisk Extreme Pro 480 GB card in the optibay.

    I then put on a new install of OSX EL Capitan.

    The drive is still showing a negotiated rate of 1.5 Gb/s

    NVidia MCP79 AHCI:

    Provider: NVidia

    Product: MCP79 AHCI

    Connection speed: 3 Gigabit

    Negotiated link speed: 1.5 Gigabit

    Description: AHCI Version 1.20 taken in charge

    Steps tried to solve the problem:

    -Reset the PRAM - no change

    Firmware update - SSD - no change

    Suggest solutions?

    If your Sandisk SSD uses Sandforce he'll run only to SATA 1.5 Gb speed due to a well known conflict with Nvidia MCP79 controller in your iMac. You must return it and get a Samsung or other brand that does not use a sandforce controller.
