I have a iMac (late 2012) with 2.9GHz Intel Core i5 & 16 GB Memory.
It happened before a couple of times, but the last few days it is persistently repeating the same problem. Usually when I switch on the machine, it makes the fan blow out air hard.
In the past if I put the Mac to sleep, restart or shutdown and restart, the problem stopped. However, this time, it is often and persistent.
When I work, I usually have Safari with a half dozen tabs, Lightroom, dictionary, sometimes Photoshop on all at the same time. But never very intensive heavy lifting in terms of processing images.
I read on the internet about SMC (System Management Controller) and how to reset, which I followed but not very successful this time.
How serious is this problem? Is it the beginning of my Mac’s death?
If there is someone with the same experience who successffully remedied the problem, I would like to hear how.
Thanks you in advance
