It’s happened to me. One afternoon while editing a photo I suddenly notice this thin red-pink line running down vertically on the display.
My iMac is a 2017 model with Retina display and fusion drive purchased in late 2018. When this problem appeared I had exactly 6 days before my 12 months warranty expires! Lucky me!?
I tried searching for solutions online but no help.
I contacted Apple support online live chat to see if there’s anyway the issue can be fixed. The live chat support was pretty efficient.
Someone named Austin tried to help. The following are the steps we tried.
Possible Solution 1
Shut down the Mac. Power on and immediately press the following keys together, Command, Option, R and P.
I should hear two restart beeps after about 20 seconds. Thereafter I can release the keys and the Mac will restart as normal and hopefully no more redline.
I did not hear the beeps and the redline is still present.
Possible Solution 2
Shut down the Mac. Unplug power point and wait for 15 seconds. Plug back the power source and wait 5 seconds before power on.
That didn’t help either.
Possible Solution 3
Unplug all peripherals and restart. Issue persists. Bummer.
I’m advised to send in the Mac to a service center as it looks to be a hardware issue.
Give the above a try, hopefully they solve your Mac problems.
What’s Up With My iMac?
I sent my Mac to QCD Technology in Subway Pyramid, an authorised apple service center that only does repair and support.
UPDATE: I received an email from QCD saying my iMac has been repaired and is ready to be collected exactly 8 days after I sent it in, online status check before that says “Waiting for parts”.
I feel that’s a fair timeframe and I’m happy to get my machine back in a week. But mine is really a straightforward case as when dropping it off, they checked and clarified it’s just a screen replacement that’s required.
The service personal did point out their Standard Operating Procedure is 3-5 days for checking and 7-10 days for repair. That’s a total of 15 days, 19 days if you include weekends. Longer still if there are public holidays.
2 to 3 weeks is a long time I’m this day and age. A VERY long time if you depend on that hardware to make a living. What would you do if you need to wait that long?
My advise would be you can send your hardware to places like this if under warranty. Otherwise, if paying for the repair, check how long the service will take and decide from there.
Leave me a comment if this post is any help at all.
