Q: iMac 27" Late 2013 - Random Shutdown
My iMac 27" Late 2013 - Have this random shutdown issue, like power chord is pulled out..randomly. I can only start it by plugging out the power cable and waiting for 5 mins and then restarting it.
When I explored the forum it seems the problem dates back all the way to 2010, it is a shame that the problem still persists on such an expensive iMac after all these years and apple is unable to provide a definitive solution.
My machine is less than a year old, still under warranty, also under Apple Care, took it twice to the service centre, here are the sequence of events:
- They have reset the SMC, PRAM, re-installed OS during first visit, problem persisted
- Spent an hour on phone support, again did a web-install of the OS, moved from ElCapitan to Yosemite, problem persisted
- Took it again, they replaced the Main Logic Board...the problem is still persisting
I read a lot of theories online but no definitive solution. Here are some of the theories I came across:
- RAM 16 GB causing the problem...but mine is 8 GB
- All slots of RAM is filled...but mine has only 2 slots filled
- It happens only on i7...but mine is a i5 machine
- Could be because of the UPS, not having a good sine wave....wonder how to test it though !!
Has anyone come across this problem and solved it definitively...please help, as I am losing trust with Apple engineer's ability to solve it...wow! it sounds strange isn't it, world most innovative and valued company is unable to fix such a common problem that numerous customers are facing...and we are losing trust with them.
I am in Bangalore India, need to check on the consumer rights on this, any inputs on this will also help as I believe I deserve a replacement for this defective product. If it was the US, if it is a lemon (take it to fix the same problem 3 times)...even cars get replaced. Wonder how it works here. Any lawyers on this forum?
Dear fellow Apple admirers and lovers of mac (I am one too!) please help.
iMac (27-inch, Late 2013), OS X Yosemite (10.10.5)

Since my iMac was under warranty as well as under Apple care, the service engineer visited home and changed the power supply board (I believe it is also called the SMC Logic Board...not sure) at home itself...finally I the problem is addressed
Thanks Mike !
