DO NOT touch the lcd and be extremely careful with the connectors.This has long been covered and discussed at great length here and/or at dedicated placed such as MacRumors so you're kind of (4year) late with your query. If you think gloves will solve this you are wrong. just having your shirt brush against it leaves marks and you can't clean it. Also be extremely careful with the LCD screen. I'm at a loss and don't want to pull it out because it just runs so much faster for video editing but using the machine as an audio workstation is now impossible because of the noise from the fan. It's the correct processor that people have used the i7 870. So either I screwed up my logic board or it just doesn't like the i7 processor. Annoying! I've researched a number of forums and found no way to resolve this, I also know there are a number of people with the same problem. I installed an i7 in my 2010 27" i3 iMac and the system works, it reports the correct stats for the i7 but the cpu fan runs at high speed from boot. This appears to be my optimal configuration for this 2010 27” iMac I’m back to High Sierra 10.13 with APFS, 1TB internal SSD and 32Gb RAM.

The slow GPU makes it completely unusable.

March 2019 - I have abandoned using Mojave 10.14 on this 2010 27” iMac.

This quote is from DosDude1 himself: “Radeon HD 5xxx and 6xxx series video cards are not, and most likely never will be, supported under Mojave or later.“ It will barely run and the experience is terrible.

Don’t install Mojave or Catalina on this machine.

Please note - this 2010 iMac (11,3) built in video card is *NOT* Metal compatible so video acceleration is DISABLED with Mojave which makes your iMac screen refresh sluggish, Photos to go black and other graphics anomalies but everything else is stellar.

September 2018 - It’s been 6 years, yes SIX years! since I did the upgrade and I still use this iMac in anger every day! Now running Mojave 10.14 with APFS, using Dosdude's Mojave Patcher.

November 2017 - It’s been 5 years since I did the upgrade and I still use this iMac in anger every day! Now running a OWC 1TB SSD and High Sierra 10.13 with APFS.

Now running Sierra 10.12 Beta 2 with zero issues other than the usual beta bugs. The system continues to amaze with its longevity. New Notepad app rocks as does a stable version of Apple Mail (at last), and now that the abomination that was 'discoveryd' is dead and the tried and true 'mDNS-Responder' is back, networking is stellar once again. Only Handoff does not work (see above) but everything else is rock solid. With these simple mods, I have gained years of additional service out of this "obsolete" machine!

Not as fast as my Haswell Macbook Pro or 2010 Xeon 12 proc Mac Pro, but still rock solid. Continuity works but Handoff does not (lacks built-in Bluetooth LE v4.0). System continues to be fast - but is starting to show its age compared to Sandy Bridge, Ivy Bridge and Haswell architectures! Newer apps are starting to creak at the seams & the beachball is now a fixture.

April 2014 - 2 years later : now running OS X 10.9 Mavericks successfully with zero issues.April 2013 - 1 year later : This system has been absolutely ROCK SOLID with no crashes, no kernel panics and no freezes!.

If you upgrade or change the HD, you will need to buy HDDFanControl software to control the HDD fan which will run at full speed otherwise.

#MAC EL CAPITAN UPGRADE INTEL DUAL UPDATE#
