Q: kernel panic
I bought my iMac November 2014. It ran well until about April and since then, I've been getting all kinds of kernel panic.
I have been on the phone with Apple reps many times, each time taken up to 3 hours.
I have been on chat mode with Apple reps many times, and each time taken up to 2+ hours.
I had been told to take the iMac in to Apple store. They replaced the 3TB hard drive. I had reinstalled from Time Capsule. I had reinstalled Yosemite.
The fréquence of panic dropped from 4, 5 time a day (within 8 hours) to once a day... but lately, it returned to the 4, 5 times a day again.
I was assure by Apple reps that Kernel panic won't trash my hard drive but that was not true.
The reason I had to replace my MBP last November was my 8TB external hard drive was trashed after many kernel panics.
What I am trying to understand is, what the hack is kernel panic?
A web search says the computer does not work well with some software and it shuts down to protect itself.
But I have kernel panic even when the computer is not running any software. I was looking at 16 blank windows on 2 monitors with nothing running and it kicked out on me.
I have repaired Photos.
I have disk utility checked the thunderbolt hard drive.
I use only Apple cables.
Abut the only thing I don't know how to check is the 3TB time capsule. It says it is full and deleted some files. But I don't thing that can cause any conflict with anything.
I have new batteries in the wireless keyboard and the wireless track pad.
The DVD is not even plugged in.
The old Cinema display seems to be working fine.
So, what is a kernel panic?
What does it do? Why does he do it?
What is running in the background that I don't know? I even deleted the HP folder so it won't load at start up.
How do I check if it is bad ram?
The iMac is retina 5K 27 inches late 2014, 4 GHz i7, 32 GB 1600 mHz DDR3, AMD Radeon R9 M295X 4096 MB. It's all Apple.
Please help.
The interruption is scary and believe me, I will never recommend anybody to buy any Apple computers any more. But I still need to try and fix mine.
Please help me.
Eddie
iMac with Retina 5K display, OS X Yosemite (10.10.1)
