iMac 27" Mid-2011 | Booting loop and Green lines | Genius Diagnostic


Dear all

This iMac was donated to me by my father, and I'm determined to repair and upgrade it. COVID has ruined my offline business so, I'm now pointing in a different direction. This iMac needs to be used for web design and other such activities. I already have a MacBook Air 2017, which could aid in the restoration of the iMac.

What I would like to do is, top up the RAM, upgrade to SSD, upgrade video card and CPU. Any other suggestions would be greatly appreciated.

I have little experience with repairing computers, although I'm fairly competent when it comes to following technical instruction. If there are any here that would be willing to give me some advice, as to what steps I need to take, I'd be very grateful.

Here are the results of the 'Apple genius bar' diagnostic test and Technician's notes.

Problem Description/Diagnosis

Issue: iMac is booting with Apple logo and then restarting after loading bar and just loops, also there are vertical green lines

Steps to Reproduce: Verified issues

Managed to run video test which passed

Also MRI all passed

Storage diagnostics failed to run

Attempted twice

Loads to grey screen

Cosmetic Condition: NA

Proposed Resolution: Positioned as Mac is an obsolete model unable to repair any hardware

Potentially could have iMac plugged into external monitor to bypass green lines

Could attempt a clean restore if OS or create a external bootable version of OS

New hard drive might be needed, worse case scenario logic board

Resolution: Service Denied

Reason: Desired Repair Type Unavailable

Hard Drive Size: 1000

Memory Size: 4096

At this point using your MacBook Air create a bootable USB OS Installer Using the macOS you currently have on it

Use it to boot up your iMac using the Option key at startup to select it. What happens then?

The GPU on this model is a know issue and was the subject of an Apple recall in the past. Hook it up to and external monitor and see if you get the same results. If so, replace the GPU. Do not get a used one as it will be subject to the same issue. Here’s the one I use for replacement:
