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
Thank you for reading.

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?
